Under Ground Water Level Measurement

HYDROSTATIC EXPERT 7070
The very precise piezo-resistive sensor is supported by pressure and temperature compensation.
The output signal is 4-20mA and connecting the transmitter directly to for instance a Mµ Connect RTU
is very easy, providing the option of Level logging, alarms or controlling the pumps.

DRINKING WATER
- Expert 7070 is designed by MJK for the drinking water and surface water industry.
- The body and the built-in atmospherical air pressure compensation provide stable and trustworthy piezo resistive measurements in boreholes, wells, tanks, water reservoirs and basins worldwide.
- Not only does Expert 7070 provide exact and stable measurement, but the construction ensures a long lifetime, low service requirements equals low running cost.
- Created in AISL 316L stainless steel and equipped with optional temperature measurement the user can keep track of both level and temperature even in boreholes.
- The output signal is provided in 4-20 mA and Expert 7070 has a programmable Zero point, but the entire measuring range can be adjusted by the end-user for individual specifications.
