M-55 SERIES FIXED SET POINT FLOW SWITCHES Fixed Set Point Piston Flow Switches with Inline Flow

Utilizing a single moving part which responds to fluid (liquid or gas) flowing within a system, M-55 Series Fixed Set Point Flow Switches monitor increasing and decreasing flow. When triggered, the M-55 Flow Switch will be within 10% of the desired set point, with repeatability of 5%.These piston flow switches are suitable for a wide range of industrial applications due to their many available materials of construction – including acrylic, aluminum, PTFE, PPE and stainless steel. The flow switches operate only when fluid flow is positively established. The 1/8” port sized M-55 Flow Switch features a flow range up to 750 CCM (0.19 GPM) for water and 25 SLPM for air*. M-55 Series 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 pre-calibrated set point ranges for applications that do not require a custom calibrated range.
