M-100 SERIES ADJUSTABLE FLOW SWITCHES Adjustable Piston Flow Switches with Right Angle Flow

The M-100 Series is an adjustable flow switch with right-angle flow that comes in 1/8” and 1/4” port sizes and has a flow range of up to 170 CCM for water and 60 SLPM for air. This extremely accurate adjustable flow switch provides repeatability of 5% and has options for SPST and SPDT configurations.

The M-100 Series Adjustable Flow Switch has been engineered to monitor vital sample flow parameters for instrumentation in process control and inert blanket gasses. 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.
