Metex 3200U Ultrasonic Flow & Level Monitor - Manual (Page 20)

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
³ 12"/30.5 cm (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.
