DLT 2.0 Differential Level Transmitter
CALIBRATION
- for Level/Inventory Applications
1. Before starting the calibration determine:
a)
MAX RANGE = ________________
(Maximum range = distance from Sensor to Zero level)
b)
MAX LEVEL = ________________
(Maximum level of product being measured)
c)
MIN RANGE
= ________________
(Distance from sensor to Max Level)
Minimum range = MAX RANGE - MAX LEVEL
(must be at least 8" / 203 mm depending on sensor model)
2. Check the maximum range with the sensor installed:
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.
MINIMUM RANGE:
In the
CALIBRATION
menu:
-
Press
to get to
Min Range
-
Press
to move the cursor under the digits
-
Use
or
to set the minimum range
Note
:
Min Range
must be at least 12" (30.5 cm) for PZ32T sensors, 16"
(40.6 cm) for PZ52T and PZ34 sensors and 8" for PZ15 sensors. For correct tank
volume calculation in
Hrt
mode
Min Range
must be the actual distance
from the end of the sensor to the top of the tank.
