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 transducer location. The transducer 
should be centered above the flume approach section and mounted 8"/203 mm (minimum) above the 
maximum liquid level (depending on sensor model). 

The transducer should be protected from physical damage and the transducer 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.
