The surge tank water level is monitored by a differential pressure sensor with built-in signal conditioning that generates a 4-20 mA signal proportional to the water depth.

The value is considered valid if the current measured is greater than or equal to 4 mA (not an open circuit).  The low and high thresholds are based upon the required flow turnover rate for the pool volume and a maximum to avoid issues (channeling) in the filter tanks.
