5.16.1 Dual-Float Brine Sensor (D-10)
Part No. 30-0232-D-10B
The Dual Float Brine Sensor (D-10) ( Figure 5-17 ) is very similar to the
30-0232-D-10, but unlike the other dual float sensors it measures a
level of liquid that is already present in the tank. The bottom float of
the brine sensor will remain in the up position in a normal condition.
When in alarm, the sensor will have either triggered the upper float or
the level has dropped below the bottom float.
Maximum Wiring Length is the maximum length of cable to be used
to connect all sensors on an individual channel. This length includes
run of cable from VSmart to each sensor board in the string.
