Micro sensors MPM4710 recording transmitter is power supplied by battery and operates continuously without manual control. It is designed with the capability to record changes of level or pressure consecutively. With the collection interval set, this transmitter can operate to record data from days up to years.
Moreover, MPM4710 recording transmitter has very low power consumption and an absolute gage pressure sensor mounted in. It is suggested to install another MPM4710 for atmosphere recording when it is used to measure shallow level, for sake of atmosphere changes. The accurate level is the pressure difference between those two measurements.
