Booth 2314. MCG 1090 Level Alarm Probe brings high technology to overfill and spill protection. A solenoid physically moves the displacer as an actual level would, and the optional remote self-testing feature makes regular testing of the probe easy and convenient. Probe can be wired to be tested from tank side or the control room. MCG1095 offers the same features but needs no wires at all. It contains a lithium battery which will totally power the unit for at least one year. Using proprietary algorithms, it instantaneously sends back any alarm conditions as well as continually checking battery conditions and probe electronics.
