Flange Mount Level Transmitter – UPA2 – 457 – GL

Flange Mounted Level Transmitter – UPA2 – 457 – GL

Level transmitter made of CuNiFe alloy, seawater-proof
The hydrostatic level probe UPA2-LMK 457-GL was designed for severe conditions, especially for navigation or offshore applications.
Due to the housing material CuNiFe, a special copper-nickel alloy, in combination with several mounting types, the LMK 457 can be used with all media occurring in the field of navigation, and with various tank, container and basin configurations.
