Housed in two IP67 waterproof and UV resistant casings and using a built-in battery pack, the system provides municipals periodic or on-demand, continuous, and reliable measurements of the following parameters simultaneously: Free Chlorine Conductivity Turbidity Pressure pH Flow (internal flow meter) Redox Temperature Measurements data is stored locally and also transmitted via cellular communication to a web-based application allowing you to review measurement results, alerts, and modify settings anywhere anytime. © Blue I Technologies 7 Introduction 1.1 Overcoming the Urban Challenge Even in urban places where power supply and communication are at reach, the main barrier of real-time, online water quality monitoring is the high cost of the monitoring station itself. The Smart NRG system eliminates the cost of the monitoring station. 1.2 Functional Overview Free Chlorine Measurement A passive-operated sensor with gold cathode and silver chloride anode. The system applies a low voltage 20mV to the sensor keeping it in measurement-ready stat at all times and preventing from entering sleep mode when it is not measuring. Measurement range: 0 – 2 ppm or 0 – 10 ppm Resolution: 0.01 ppm Repeatability: 1% span Measurement range: 20 to 5000 µSim Accuracy: 2 – 4% Measure Value Resolution: 1 µs Repeatability: 0.01 Conductivity Measurement A k=1 cell constant conductivity sensor. Low current components in the electronic board enable the sensor to measure using low power, and to continue measuring while the battery enters end of life period. 8 © Blue I Technologies Functional Overview Turbidity Measurement A white light nephelometry (90° and 180°). The turbidity sensor is a proprietary design of Blue I. Low current components in the circuit enable the sensor to measure using low power, and to continue measuring while the battery enters end of life period. Bubble removal and cleaning is done automatically by an internal mechanism. Measurement range: 0 to 20 NTU Accuracy: 2 – 4% Measure Value Resolution: 0.001 Repeatability: 0.01 Measurement range: 0 to 14 Resolution: 0.01 pH Repeatability: 0.01 Measurement range: 0 to 2000 mV Resolution: 1 mV Repeatability: 0.01 Measurement range: 0° C to 100° C Resolution: 0.1° C Repeatability 0.1 Measurement range: Adaptive Accuracy: 3-5% Measure Value Repeatability: 0.01 Measurement range: 0 to 10 bar (0 to 145 psi) Accuracy: 3% Measure Value Resolution: 0.05 bar (0.72 psi) pH Measurement Provided by a ceramic diaphragm and gel filling electrode.

Flow Measurement Provided by a pulse sensor (not provided) Pressure Measurement Provided by a pressure membrane. © Blue I Technologies 9 Introduction 1.3 System Overview The Smart NRG water quality analyzer is composed of the following modules: 1.3.1 Electronic Board Module The electronic board controls the activity of the system. The board is designed to manage all measurement with low power consumption and to save water usage by flowing water into the system only when measurement is performed. A USB port allows you to connect a PC to the board for setup, calibration, status information, and data download. The board stores measurements and status information locally and transmits the information via a modem per your configuration. 10 © Blue I Technologies System Overview 1.3.2 Sensors Board Module The sensors board controls the electrical connection to the sensors, value readings, calibration curves, reading conversion. The pH, redox, and temperature sensors consume low power during regular operation and can go into standby mode immediately when not measuring. Low current and low voltage (up to 7 Volt) components in the circuit enable the free chlorine, conductivity, and turbidity sensors (high power consumption) to measure using low power and to extend their operation into the end-of-life period of the battery. © Blue I Technologies 11 Introduction 1.3.3 Flow Cells The system includes three flow cells: Flow cell 1 – holds the conductivity sensor. The cell is designed to enable fast temperature balance between the water temperature and ambient temperature. Flow Cell 2 – holds the free chlorine, pH, redox, temperature, and flow sensors. Water flows into the cell only when measurement is scheduled. The water flow is indicated by the inductive sensor. To save power, the sensors perform measurements only when water flow is indicated. The cell’s water flow is 35 liters/hour. Water pressure to the cell must be adjusted to 0.5 – 1 bar. Flow cell 3 – specifically designed to hold the turbidity sensor and features automatic cleaning and a water outlet for manual cleaning. The cell’s open design enables air bubbles escape from the cell and ensures accurate measuring with minimal maintenance. Flow cell 1 (Conductivity) Flow cell 2 (CL/pH/Redox /Temp) Flow cell 3 (Turbidity) Leak Detection Float 12 © Blue I Technologies System Overview 1.3.4 Automatic Leak Detection The Smart NRG system is equipped with a sensor connected to a float. In case water leaks inside the controller casing, the float, which is located at the bottom of the casing, rises and the sensor identifies the leak. The sensor will send an alert to the operator via SMS or email and will close the main valve.

Always use digital calibration devices. Alternatively, standard solutions may be used. Make sure the standard solution is not expired or contaminated prior to using. Always take water for calibration from the sampling valve, NOT from the process line directly. The analyzer should always be calibrated with water from exactly the same source. Perform chlorine calibration every six month according to manufacturer instructions. To calibrate free chlorine: 1. Before calibrating chlorine, calibrate temperature and pH and verify that both parameters are at normal operating levels. 2. Fill the sampling container from the flow cell. 3. Test the water sample for chlorine using a digital photometer or other external testing device. 3.3.4 Calibrating Other Sensors Calibration of other sensors requires the use of a reliable external testing device or standard solution. When using an external testing device, follow the chlorine calibration sequence making sure to take the water sample from the same water supply of the sampling cell (sensors). Perform Redox and pH calibration once a year. We recommend calibrating both Redox and pH whenever you calibrate the chlorine sensor. Perform turbidity calibration once a year. 1. Remove the sensor, clean with a dry cloth and place in the standard solution. 2. Place the sensor in the standard solution and wait for the reading to stabilize. © Blue I Technologies 35 Operation and Configuration 3.3.5 Setting Status Mode Parameters The Status Mode Parameters enable you to set the controller Delay before measurement, Measurement interval, and Modem interval for both Normal and Turbo modes. To set the status mode parameters: 1. Click Status Mode at the bottom of screen. The Status Mode Parameters dialog is displayed. 2. Set the parameters Normal and Turbo modes as required: ◦ Delay before measurement – sets the delay in seconds before the measurement begins.

Pipe Length Up to 1 meter Up to 3 meter ◦ ◦ Recommended Delay 30 seconds 90 seconds Measurement interval – sets the measurement frequency in minutes. Modem interval – sets the data transmission frequency in minutes. The setting for the last two parameters greatly affect battery consumption. Consult the following table for typical settings. 3. 36 Measurement/Modem Interval Expected Battery Life 60 minutes / once a day 3 years 60 minutes / every two hours 2 years 15 minutes 9 months Click Apply and Close to save the settings. © Blue I Technologies Activating Manual Turbo Mode 3.3.6 Setting Battery Level Alarms Battery alarms provide alerts when the battery enters end-of-life period allowing you to replace the battery before it dies out. You can define both low level and high level alarms. A high level voltage may indicate battery malfunction that may harm the system’s electronics and needs replacement. The system is pre-defined with default settings that you can change as follows. To set battery thresholds: 1. Click Change at the bottom of the screen. 2. Type in values for low voltage alarm and high voltage alarm and click Apply to save the changes. ◦ ◦ Recommended setting for low alarm: 5.5. Recommended setting for high alarm: 8.5. 3.4 Activating Manual Turbo Mode You can manually put the system into Turbo mode, in which the system performs measurements at higher rate than in Normal mode. This is useful when you suspect a water quality event is about to occur; or when an event is already taking place and you want to closely monitor water parameters. To activate manual Turbo mode: 1. Click Status Mode at the bottom of screen. The Status Mode Parameters dialog is displayed. 2. Click Force Turbo Mode, type in the required number of measurement cycles. © Blue I Technologies 37 Operation and Configuration 3. Click Apply. 4. To exit from manual Turbo mode, set Measurement cycles to 0 (zero) and click Apply. 3.5 Configuring Automatic Turbo Mode Turbo mode enables you to closely monitor water quality events. This is done by configuring a required range (low and high thresholds) for the parameters. When parameter measurements are outside the range, the system begins measuring at a high rate until the measurement results return to normal range. This allows you to follow the event through, perform corrective actions, and verify that water quality returns to normal range. You can set Turbo mode for a single parameter, several parameters, or all of them. In addition, for each parameter, you can set low or high thresholds, the number of repeated measurements before entering Turbo mode, and the number of repeated measurements before returning to Normal mode. To configure Turbo mode: 1. Set the Delay before measurement, measurement interval, and modem interval for Turbo mode in Status Mode Parameters (see “Setting Status Mode Parameters“ on page 36). 2. In the main area, click Change next to a parameter and set the following parameters: ◦ Low Alarm/High Alarm – specify the thresholds that when exceeded, the system enters Turbo mode. For example, for pH you may define Low Alarm – 6.8 and High Alarm – 7.8. ◦ ◦ Enable – activates the low and high thresholds you have specified. You can activate either one of the thresholds or both. Retries IN – specify the number of measurements exceeding the thresholds before the system enters into Turbo mode. For example, 2 retries mean the system enters Turbo mode only after two exceeding consecutive measurements. ◦ Retries OUT – specify the number of measurement within the thresholds before the system returns to Normal mode. For example, 2 retries mean the system exits Turbo mode only after two consecutive measurements within the thresholds. 38 3. Repeat this process for each parameter as required. 4.

Battery alarms enable you to be notified when the battery voltage begins to weaken and allows you to replace the batteries before they run out (see “Setting Battery ” on page 37). 5.2 Chlorine Sensor Perform sensor maintenance whenever any of the following conditions are met: When the membrane is visibly soiled, clean the sensor. Refill the sensor with electrolyte once per season or every 12 months. Depending on the water quality and chlorine level, this period can be reduced or extended. Calibrate the sensor when necessary (see “Calibrating Parameters” on page 32). 5.2.1 Cleaning the Sensor Caution: Do not use chemicals that reduce the surface tension. When using hydrochloric acid, observe all the safety regulations. 1. Remove the sensor from the flow cell. © Blue I Technologies 49 Maintenance 2. Clean the membrane mechanically with a gentle water jet or swirl in a solution of 2% hydrochloric acid (no other additives). 3. If the membrane is still visibly soiled, replace the membrane. 5.2.2 Replacing the Membrane and Refilling the Electrolyte 1. Unscrew the measuring chamber from the shaft. 2. Unscrew the front screw cap holding the membrane. 3. Remove the membrane and replace with a new membrane. After replacing the membrane, you must refill measuring chamber with electrolyte. 4. Screw the cap back. Do not swallow the electrolyte. Avoid electrolyte contact with skin or eyes. In case of accidental contact, wash with a lot of cold water. In case of eye inflammation, contact a doctor immediately. Wear safety glasses and gloves when working with the electrolyte solution. Do not touch or damage the electrodes. The electrolyte is sensitive to oxidation: Always keep the electrolyte bottle closed after use. Do not transfer the electrolyte to other containers. The electrolyte should not be stored for more than one year and should be clear (not yellow) in appearance (for use by date, see label). Avoid forming air bubbles when pouring the electrolyte into the measuring chamber. 5. Unscrew the measuring chamber from the sensor shaft. 6. Hold the measuring chamber at an angle and fill in about 7 to 8 ml (0.24 to 0.27 fl.oz) electrolyte, up to the internal thread of the measuring chamber. 7. Tap the filled measuring chamber several times on a flat surface so that air bubbles can detach and rise. 8. Insert the sensor shaft vertically from above into the measuring chamber. 9. Slowly tighten the measuring chamber to the stop. Excess electrolyte is pressed out of the sensor during the tightening. 5.2.3 Reconditioning the Sensor Long-term operation (above a week) in chlorine-free medium (very low sensor currents) leads to a deactivation of the sensor. This is a continuous process that reduces the sensor ability to work properly. After long-term operation in a chlorine-free medium, you must recondition the sensor. 50 Prerequisites: De-mineralized water (or electrolyte) Polishing sheet (Emory Cloth) Beaker © Blue I Technologies Chlorine Sensor Approximately 100 ml (3.4 fl.oz) of chlorine bleach liquid NaOCl approximately 13%, pharmaceutical quality (available at chemical stores or pharmacies) To recondition the sensor: 1. Remove the sensor from the assembly. 2. Unscrew the measuring chamber and set it aside. 3. Polish the gold cathode of the sensor using the polishing sheet: a. b. c. Place a wetted strip of the sheet in your hand. Polish the gold cathode by moving it circularly on the strip. Rinse the sensor with de-mineralized water (or electrolyte). 4. Top up the electrolyte if required and screw the measuring chamber back into place. 5. Fill the beaker with chlorine bleach liquid to about 10 mm (0.39") and position it safely. Caution The sensor must not touch the liquid. 6. Place the sensor in the gaseous phase about 5 to 10 mm (0.2" to 0.39") above the chlorine bleach liquid. 7. The sensor current increases. The absolute value and the speed of increase depend on the temperature of the chlorine bleach liquid: ◦ ◦ When the sensor reaches a high chlorine value, leave it under these conditions for 20 more minutes. If the chlorine value is not increasing, cover the beaker to minimize air movement. 8. Re-install the sensor in the assembly. 9. Re-establish flow. The sensor current will normalize. 10. After sufficient settling time (no noticeable drift), calibrate the sensor. © Blue I Technologies 51 Maintenance 5.3 Conductivity Sensor Regular cleaning of the conductivity sensor ensures its long-term operation. The cleaning frequency depends on the water source being tested. As general guidelines, clean the sensor whenever there is significant visible dirt, when the measurement accuracy is affected, or before calibration. To clean the conductivity sensor: 1. Close water flow to the conductivity flow cell and remove the sensor. 2. Wash the sensor under a stream of water to remove dirt. 3. Use a soft cloth to remove any additional dirt and oil. 4. Replace the sensor and resume water flow. 5.4 Cleaning the Flow Cells Over time, the flow cells can accumulate dirt and stains on their side walls. This may affect the accuracy of measurement. Regular cleaning of the flow cells ensures long-term operation of the system. As general guidelines, clean the flow cells once a year or when the cells are visibly stained. 52 To clean the flow cells: 1. Close the water flow to the cell and remove the electrodes. 2. Close the system water outlet valves. 3. Fill the cells with the Blue I cleaning solution (Nakita) up to the marked line. 4. Allow the material to rest for 40 minutes in the cells. 5. When the cells are clean, open the water outlet and let the material drain from the system. 6. Close water outlet, reconnect the sensors, and resume water flow. © Blue I Technologies 6 Troubleshooting 6.1 Issues and Workarounds Issue Cause Possible Solution Water is dripping from the controller Leakage from pipe connectors.
