OCF 5.0 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.
