Available in Adobe Acrobat pdf format Page 3 OCF 6.1 Open Channel Flow Monitor CONNECTIONS: POWER INPUT: The standard model requires AC power input between 100 to 240 VAC 50/60Hz. No adjustments are necessary for voltages within this range. Optional DC: 9-32 VDC. Connect to + and - terminals. Optional Thermostat and Heater modules are available rated for 115 VAC or 230 VAC. IMPORTANT NOTE: To comply with CSA/UL electrical safety standards, AC power input and relay connection wires must have conduit entry to the instrument enclosure. Installation requires a switch, overcurrent fuse or circuit breaker in the building (in close proximity to the equipment) that is marked as the disconnect switch. Risk of electric shock. Loosen cover screw to access connections. Only qualified personnel should access connections. Note: Use of instrumentation over 40°C ambient requires special field wiring.

Damping Choose between OFF, FIR (Default), or LOW PASS. When measured flows are outside the Window of the running average, the FIR filter will reduce the damping average so that a fast response can be made to the sudden change in flow rate. The LOW PASS filter will ignore measured flow rates outside the Window, while holding the running average, until there are enough data points outside the Window to cause a step-response to the new measured value. While measured flows are within the Window of the running average, both the FIR and LOW PASS filter behave the same. Percent Set the damping value for level reading. Lower values provide fast response to changing levels, and higher values provide a slower response. Factory default value is 10%. Window The Window sets a boundary around the running average, where if the measured value falls outside the window, the meter will make a more rapid response to the new value (FIR), or will hold the last reading until enough values are outside the window and then make a step response to the new value (LOW PASS). Press to return to Menu Selections. Page 14 OCF 6.1 Open Channel Flow Monitor CALIBRATION - for Open Channel Flow 1. Before starting the calibration determine: a) MAX RANGE = ____________________ (Maximum range = distance from the Sensor to Zero flow point) b) MAX LEVEL = ____________________ (Maximum level of flow through flume or weir) c) MIN RANGE = __________________ (Distance from sensor to Max Level) Minimum range = MAX RANGE - MAX LEVEL (must be at least 8" / 20.3 cm depending on sensor model). 2. Check the maximum range with the sensor installed by: a) When liquid is at zero level press to view the Range reading in the Status menu. Use this range measured by the OCF 6.1 as the Max Range setting. or b) Carefully measure distance from sensor to zero level with a tape measure, and use this measurement as the Max Range setting. NOTE: The OCF 6.1 will not detect targets beyond user entered Max Range.

CHANNEL SETUP Type Custom. Used to configure the OCF for a flume/weir type not already selectable in the meter. K & n Format: Flow = K * H^n; Where H = head Use the Greyline Find K&n software (included on Flash drive shipped with meter) to determine the K&n values to use. The K&n software requires that you enter up to 10 head points and the corresponding flow rates for each point. A curve fit is performed, and the software provides the K and n values to program into the meter. You can also contact a Greyline technician for these values. IMPORTANT: The OCF requires that the K & n coefficients are from a flow equation where flow is in units of CFS, and head in units of feet. If you determined a K & n coefficient outside the use of the Greyline Find K&n software, be sure that the coefficients are in these units, otherwise you will need to convert them before entering them in the meter. The Units/Mode settings in the meter can be configured to whatever units you desire for flow rate and total. The meter will automatically convert the K&n in CFS to the programmed units in the Units/Mode menu for the flow rate and totalizer display. IMPORTANT: If you are uncertain about how to convert your K and n constants please contact our technical support team and we'll be happy to assist. Example: For a 2 foot Parshall flume, the discharge equation for a flow rate in GPM, and head in feet, is GPM = 3590 * H^1.55. Since head is already in feet, we only need to convert GPM to CFS. 1 CFS = 448.8 GPM, so dividing by 448.8 give us CFS = 8.0 * H^1.55. This is the equation we would enter into the OCF 6.1 for this flume.

This is used when the level in the flume/weir/tank is at the zero level point, to quickly calibrate the Max Range so that a manual measurement does not need to be taken. Barrier Standpipe Long Pulse Gain Will be set from the factory. NO when no intrinsic safety barriers are installed, and YES when barriers are installed. Will be set to NO from the factory. Only select YES after factory recommendation to do so. Reduces the frequency of pulses sent from the transducer, to reduce the potential negative impact of false echoes from inside a tank or standpipe. Will be set to NO from the factory. Only select YES after factory recommendation to do so. Displays a read-only value of the automatic gain level. Higher values indicate that the received echo is being amplified more. Values near the max of 255 indicate maximum amplification, and sources of echo attenuation should be investigated, such as wrong wire types spliced into the sensor cable, surface foam, vapors in the atmosphere, or a transducer not parallel to the fluid surface. Page 23 SENSOR MOUNTING METHODS OCF 6.1 Open Channel Flow Monitor Page 24 OCF 6.1 Open Channel Flow Monitor SENSOR MOUNTING/LOCATION - Open Channel Flow Applications Each sensor is equipped with a 3/4 inch isolation coupling which MUST be used in your installation. A threaded nipple or length of conduit may be used to position the sensor at the desired height. The sensor should be hand-tightened by turning the sensor stem only. DO NOT use a wrench and do not over tighten. IMPORTANT: Follow the flume manufacturer's directions for sensor location. The sensor should be centered above the flume approach section and mounted 8"/203 mm (minimum) above the maximum liquid level (depending on sensor model). The sensor should be protected from physical damage and the sensor cable should be routed in a separate metal conduit. Because the sensor is equipped with a temperature sensor, it should be shielded from direct sunlight. Use the PVC "isolation coupling" supplied with the sensor and hand-tighten the sensor/coupling assembly onto your mounting stand. Do not clamp directly to the sensor or to the isolation coupling. Page 25 OCF 6.1 Open Channel Flow Monitor TYPICAL SENSOR POSITIONING FOR FLUMES AND WEIRS Always refer to the flume or weir manufacturer's instructions for correct measurement point upstream from the flume or weir. Location of the sensor is critical for accurate flow measurement. If manufacturer's instructions are not available, the following guidelines are generally accepted. 1. PARSHALL FLUME: Position the sensor at 2/3 Approach as illustrated above. Sensor height must be 8" (203 mm) or more above the highest water level. 2. PALMER BOWLUS FLUMES: Position the sensor at ½ the flume Diameter upstream from the throat of the flume. Sensor height must be 8" (203 mm) or more above the highest water level. 3. V-NOTCH WEIRS Position the sensor at 3 x maximum Head upstream from the weir plate. Sensor height must be 8" (20.3 cm) or more above the highest water level. STILLING WELLS Stilling wells are recommended to reduce the effects of turbulence as water flows through the flume or weir. The OCF 6.1 sensor is centered over the stilling well. Sensor height must be 8" (203 mm) or more above the highest water level. The well must be kept clean of sediment and deposits on the side walls. Page 26 OCF 6.1 Open Channel Flow Monitor ZERO POSITIONING OF SENSOR - Open Channel Flow Applications Locate the sensor at the position upstream from the throat of the flume or weir plate as recommended by the manufacturer. A technique for accurate sensor height adjustment is shown: Page 27 OCF 6.1 Open Channel Flow Monitor ENCLOSURE INSTALLATION Locate the enclosure within 20 ft (6 m) of the sensor (500 ft -150 m optional). The enclosure can be wall mounted with the four mounting screws (included) or panel mounted with Option PM Panel Mount kit from Greyline Instruments. Avoid mounting the enclosure in direct sunlight to protect the electronics from damage due to overheating and condensate. In high humidity atmospheres, or where temperatures fall below freezing, Option TH Enclosure Heater and Thermostat is recommended. Seal conduit entries to prevent moisture from entering enclosure. NEMA4X (IP66) WITH CLEAR COVER 1. Open hinged enclosure cover. 2. Insert #12 screws (supplied) through the four enclosure mounting holes to secure the enclosure to the wall or mounting stand. Additional conduit holes can be cut in the bottom of the enclosure when required. Use a hole saw or Greenlee-type hole cutter to cut the required holes. DO NOT make conduit/wiring entries into the top of the enclosure. Note: This non-metallic enclosure does not automatically provide grounding between conduit connections. Grounding must be provided as part of the installation. Ground in accordance with the requirements of the National Electrical Code. System grounding is provided by connecting grounding wires from all conduit entries to the steel mounting plate or another point which provides continuity. CLEANING Cleaning is not required as a part of normal maintenance.
