Flow rate alarms
Utilized in applications such as mobile hydraulic equipment and industrial process control, ensures sufficient flows of coolants and lubricants.
UL-approved: Lake Flow Alarms are UL Approved for loads up to 10 amp @ 110/220 VAC.
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 in outdoor applications and in environments where liquid tight seals are required.
Simple on/off logic: Positive alarm points using 10 A., 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.
Unrestricted mounting: Allows the designer to install the monitor in any orientation-horizontal, vertical or inverted.
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.
Quality assurance: Can be an integral part of a quality control system, yielding consistent system operation.
Engineering specifications:
The in-line Flow Rate Monitor/Alarm Shall:
• Have field adjustable, dry-contact, alarm setting(s)
• Use the variable annular orifice technique with compression spring recoil
