Vane & Piston - Variable Area
 


Model   Body Material

    335      Varies upon                    Application


These meters operate by the variable-orifice principle. The liquid pushes against a spring-loaded swinging vane or piston. They can handle shocks or overflows up to 1-1/2 times rated capacities. Available with Switches, 4-20mA Transmitter outputs, Voltage Transmitters, Potentiometer outputs, and Intrinsically Safe outputs.
