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.

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
