Example 1:
Setup of the pressure transducer for
“PRV
I
nlet pressure”
.
Note: The PRV inlet pressure is required by
Sentinel 2 (and also PressView) to be
mapped to “channel 1”.
Clicking the cog button for channel “1” gives
details of the source of measurements that
will be used
for the “channel 1” memory area.
It should be modified if required.
In our example, the pressure transducer is
internal and has a range of 0-10 bar (0-100m).
Note: The pressure range can be found from examination of the model number for
internal transducers, or a calibration details label on the cable of external
transducers supplied by HWM.
Our example unit, Sentinel 2 unit has 4
available input transducers (input sensors):
•
Pressure1: An internal pressure
transducer (located at the port labelled
“PRV inlet pressure”).
•
Flow Bi: An electrical interface for a
flow meter that has a compatible
electrical interface
i.e., a volt-free pulse output.
•
Pressure2: An internal pressure
transducer (located at the port labelled
“PRV outlet pressure”).
•
Temp Int: A transducer that can measure the internal temperature of the unit.
The “Input Sensor” drop
-down selector is
used to choose the electrical interface for
the channel 1 logging memory area.
Select “Pressure1”.
The “Sensor Type” drop
-down selection box
starts the configuration of how numerical
measurements from this interface will be
interpreted.
The pressure interface should be interpreted
as a reading of “pressure”.
