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/MOD
E 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.
NOTE: The SLT32 will not detect targets beyond user
entered
MaxRg
.
