Compact flow meter with integrated check valve and display.

The SBN series monitors water, glycol solutions, industrial oils or coolants. The sensors operate to the principle of spring-supported piston. The piston, located in the valve seat in the housing, is lifted by the flowing medium against the spring resistance. The position of the piston indicates the flow. The spring resistance forces the piston to return to its original position with decreasing flow, preventing backflow.

The sensor can be used in high pressures, harsh industrial environments.
