The product uses high performance pressure sensor as sensing element, which could measure liquid static pressure that is positive proportional to level depth precisely, and transform pressure signal into standard current/voltage signal output by amplifier circuit to measure accurate level depth.

The biggest difference among MB260/MB261/MB264 is the material of the submersible Level casing,MB260 is a general type with NBR tube;MB261and MB264 are its promotion version for more special measuring medium.MB261 has stainless steel tube protection,but MB264 has the anticorrosion tube to prevent from a variety of acid-base or other corrosive liquids.
