Metex 3200U Ultrasonic Flow & Level Monitor - Manual (Page 11)

CALIBRATION
- for Open Channel Flow
1. Before starting the calibration determine:
a) MAX RANGE = ____________________
(Maximum range = distance from the Sensor to Zero
level 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) Use
Æ to get to
UNITS/MODE then
È to get to
Range , then Store? Yes
(NOTE: flow must be at zero flow)
or
b) Carefully measure distance from sensor to zero level
with tape measure.
