M-64 SERIES FIXED SET POINT FLOW SWITCHES Fixed Set Point Piston Flow Switches with Inline Flow

With flow rates of up to 26 L/m for water and 1,980 SLPM for air, the M-64 Series Fixed Set Point Flow Switch is designed for monitoring increasing and decreasing flow in larger applications. This inline flow switch is available in 3/8" or 1/2" NPT ports and offers many different materials of construction options including brass, stainless steel, PVC, and PTFE.

With configurations available for single-pole, single-throw (SPST) or single-pole, dual-throw (SPDT), the M-64 Fixed Set Point Flow Switch allows 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.

Features

  • Extremely high level of accuracy within 10% of the desired set point for fixed set point models, and repeatability of 5% for all models of Malema Flow Switches.
  • Female NPT standard on flow switches providing small, compact design.
  • All Malema Fixed Set Point Flow Switches can have their own customized set points calibrated at the factory before shipping.
  • Standard pre-calibrated set point ranges on Malema Flow Switches are also available for immediate use and distribution.
  • Malema application engineers are available for consultations to provide the best possible flow switch options and materials of construction to ensure compatibility.
  • Configurations available for single-pole, single-throw (SPST) or single-pole, dual-throw (SPDT) allowing for flexibility different outputs for both the high and low set point.
  • Special configurations and different materials of construction are available. Consult the factory for details.
