Non-intrusive monitors for liquid handling systems

Featured Product from Arjay Engineering Ltd.


2852-DPM Dry Pump Monitor

Pipe monitoring for dry conditions to protect pumps and equipment

Combining the technology of capacitance with unique sensor designs provide non-intrusive monitors for liquid handling systems. The result is a low cost and low maintenance system to determine the presence or absence of product in a pipe or pump.

The 2852-DPM sensor monitors a cross sectional area of the pipe and locks in on the capacitance field of the fluid passing through. A change toward a dry condition or a liquid of a different dielectric will upset the capacitive field and initiate an alarm.

The sensing plates are embedded into a wafer flange which provides monitoring without any intrusion into the stream flow.

Features and Benefits

  • wafer flange sensor for easy installation
  • adjustable time delay and sensitivity to eliminate nuisance alarms from bubbles
  • remote electronics via standard twisted pair
  • Sensor available Intrinsically Safe for Hazardous Locations
  • PVC wetted parts for corrosive environments
  • capacitance technology responds to all types of liquids
  • non-intrusive sensor design does not restrict flow
  • capacitance technology responds to any liquid type
  • no moving parts
  • remote alarm unit mounts safely away from pipe
  • no intrusion into stream flow
