    Cs450/cs455 pressure transducer for example, if the correct elevation of the water, as measured by a staff gauge or other measurement device, is 2015.50 feet, and the cs450 provides a reading of 5.76 psig, then: 5.76 psig * 2.31 ft/psig = 13.3056 ft. So, the offset is calculated: 2015.50 ft – 13.305...
