M-100 Series Adjustable Flow Switches

Industries: Semiconductor , Industrial
Adjustable flow switch with right-angle flow, available in 1/8" & 1/4" port sizes.

The M-100 Series is an adjustable flow switch with right-angle flow that is extremely sensitive. It has been engineered to monitor vital sample flow parameters for instrumentation in process control and inert blanket gases. It is used as an auxiliary alarm monitor for flow meters and is ideally suited for applications when installed on a by-pass for determination of filter plugging. Infinite adjustment permits detection and signaling of very low fluid flows with the added capability of detection in high flows.
