Request Information

The Flow Rate Alarm is a rugged “flow switch” device that monitors flow and sends a signal using simple on/off logic if rates are out of spec. The weather tight NEMA 4x cast aluminum enclosure allows for outdoor installation and washdowns. Alarm settings are easily adjusted in the field with an allen wrench. The standard Hirschman interconnection provides easy installation and maintenance.

Applications include:

  • Cooling systems
  • Lubrication systems
  • Mobile hydraulic equipment
  • Industrial process control systems

    Field Adjustable Alarm Setting
    Only an allen wrench is required to change the flow alarm setting.

    Weather-Tight Construction
    Rugged cast aluminum NEMA type 4X enclosure allows installation outdoors and in environments where liquid tight seals are required.

    Simple On/Off Logic
    Positive alarm points using dry-contact, SPDT switches, reduce the complexity found in standard rotameter OFF/ON/OFF circuits.

    Pre-Wired with Cable Disconnect
    The standard Hirschmann interconnection provides easy installation and maintenance of the Flow Alarm and the system it is a part of.

    Economical Protection
    This monitor rapidly pays for itself as it "sounds the alarm" on incorrect pneumatic, lubrication or cooling volumes, protecting expensive equipment and reducing downtime.
