7 Network Setting The network address can be used to create separate networks using multiple gateways (that are in close proximity with one another). The network is set using the SignalFire Toolkit. The Network Group setting is used when more than 8 networks are needed. Both the network and network group must match those of other nodes for nodes to communicate. Encryption It is possible to encrypt over-the-air transmissions to prevent tampering. Encryption keys replace the Corporate ID system, so it is important that all devices connected to a Gateway have the same encryption key as well as network and network group number. To set up a Flow Totalizer to use encryption, click the checkbox labeled Enable Encryption inside the Set Corporate ID box: The encryption key box. For more details, click the Help button. The box will then change into a Set Encryption Key box, and it will prompt instead for the encryption key you would like to use. Note that keys may not contain spaces or angle brackets. Enter it and then press Set. If you are setting up a new network, you will need to set the encryption key on all of your devices. If you are adding a Flow Totalizer to a legacy network, you can simply set the Corporate ID without clicking the Enable Encryption box, and it will remain compatible with the older system. Setting the encryption key. It is also possible to hide your encryption key so it cannot be read. This is the most secure option, but if you forget your key, there is no way to recover it – you have to reset the key on every device on its network. To enable this option, select Set Encryption Key Unrecoverable under the Settings menu. Setting the encryption key unrecoverable. SignalFire Telemetry Rev 2.4
8 System Check-In Period This setting controls how often the node will read the Modbus device and forward the register data to the gateway. Modbus Slave ID The Modbus Slave ID must be set with the SignalFire Toolkit. Each remote device connected to a SignalFire Gateway must have a unique Modbus Slave ID. Turbine Meter Connection The Flow Totalizer is supplied with a 1” NPT Union to allow it to be directly mounted to a standard turbine flowmeter. The nut on the union can be loosened to allow the totalizer to be rotated to the desired orientation. Also supplied is a 2-pin connector for connection to the turbine flow meter magnetic pickup. Teflon tape should be used on the NPT connections. Pickup Sensitivity Selection For most turbine flow meters, the gain selection jumper should remain in its default “LOW GAIN” position. This provides a sensitivity of 20mV p-p. If a high sensitivity is needed the jumper can be moved to the “HIGH GAIN” position which increases the sensitivity to 5mV p-p. Flow Settings / Configuration Clock Setting The battery backed up real-time clock must be set. To set the clock to match the PC’s clock, simply click “Set to PC”. Alternatively, the time/date can be manually entered. Volume Units The Volume units set the units that the accumulated volumes and flow rate will be presented in. Volume units available are: • Gallons • Barrels • Liters • Cubic Meters SignalFire Telemetry Rev 2.4
9 Timebase Units The Timebase units configure the units used for the flow rates. For example, if the volume units are set to ‘gallons’, and the timebase units are set to ‘minute’, the flow rates will be reported as gallons/minute. Timebase units available are: • Seconds • Minutes • Hours • Days K-Factor Units / K-Factor The K-factor units set the units that the flow meter uses for its k-factor. For example, if the turbine flow meter has a stated k-factor of 50,000 pulses/gallon, select ‘gallons’ for the K-Factor units, and enter 50000 for the k-factor. Contact Hour The contract hour setting controls when the volume accumulated for today, rolls over to yesterday’s volume. The contract hour is set in hh:mm in the 24-hour format. For example, 2:30pm would be entered as 14:30. 30 Day Logging The Flow Totalizer also keeps an on-board log of the last 30 days of flow totals. This log can be accessed using the SignalFire ToolKit. From the Tools Menu, select ‘Daily Log’. On the daily log window click ‘Refresh’ to read the log file. The log can be saved as a .csv file. Flow Rate Reporting The Flow totalizer reports two flow rates, average flow rate, and instantaneous flow rate. The average flow rate is the flow rate over the configured check-in period. For example, if the check-in period is configured as 2-minutes, each check-in will contain the average flow rate over the 2-minues. The Instantaneous flow rate is calculated every 2-seconds. At check-in the most recent instantaneous calculated flow rate will be reported. SignalFire Telemetry Rev 2.4
10 Local Display The Flow Totalizer has a local LCD display (with back-light) that allows for easy viewing of the flow totals and flow rates. The display is powered on only when the button under the display is pressed. Pressing the button when the display is on, cycles through the various information screens. The display and backlight will automatically turn itself off after 30 seconds. LCD Always on The default operation of the LCD is for it to time out and turn off after 30 seconds. It will come back on when the front button is pressed. If it is desired that the LCD remain on always, this can be selected from the ‘Settings’ menu. Leaving the LCD always on will impact the system battery life, see the table on page 2 for details. Note that the LCD backlight will still turn off after 30 seconds. SignalFire Telemetry Rev 2.4
11 Remote Modbus Register Mapping The Flow Totalizer sends data to a SignalFire Telemetry Modbus Gateway. The data that is sent To the gateway is available at the gateway in registers where it can then be read by a Modbus RTU. Consequently, the node needs to have a unique (to the network it is in) Modbus slave ID which the gateway will use to store its unique data. Modbus Registers Every check-in period, the sensors are read and data is sent to the gateway. The gateway will save the data under the set Modbus ID in 16-bit registers. The register map for this system is below.
