M-50 SERIES FIXED SET POINT FLOW SWITCHES Fixed Set Point Piston Flow Switches with Inline Flow

The M-50 Series Fixed Set Point Flow Switches monitor increasing and decreasing flow. They utilize a single moving part which responds to fluid (liquid or gas) flowing within a system. These piston flow switches feature inline flow and are suitable for a wide range of applications in many industries. The flow switches operate only when fluid flow is positively established. When triggered, the M-50 Flow Switch will be within 10% of the desired set point, with repeatability of 5%.The M-50 Flow Switch features two port size options (1/8” or 1/4”) and has a flow range up to 170 CCM (0.04 GPM) for water and 5,000 SCCM for air.* M-50 Inline Flow Switches have configurations available for single-pole, single-throw (SPST) or single-pole, dual-throw (SPDT) allowing for flexibility with different outputs for both the high and low set point. All Malema Fixed Set Point Flow Switches can have their own customized set points calibrated at the factory before shipping. Additionally, Malema offers flow switches with pre-calibrated set point ranges for applications that do not require a custom calibrated range.
