DLT 2.0 Differential Level Transmitter
CALIBRATION
- for Open Channel Flow
1. Before starting the calibration determine:
a)
MAX RANGE = ____________________
(Maximum range = distance from the Sensor to Zero flow 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)
When liquid is at zero level press
to view the
Range
reading in the
Status
menu. Use this range measured by the DLT 2.0 as the
Max
Range
setting.
or
b)
Carefully measure distance from sensor to zero level with a tape measure,
and use this measurement as the
Max Range
setting.
NOTE: The DLT 2.0 will not detect targets beyond user entered
Max Range
.
