Dry pump monitor and phase detector protects pumps and equipment

The Arjay Engineering 2852-DPM dry pump monitor and phase detector uses capacitance technology with an ingenious non-intrusive design to protect pumps and equipment from damage due to dry or low volume conditions.

The unit from Arjay Engineering uses embedded sensing plates in a PVC wafer flange said to provide easy installation and no interference to the product flow.

The sensor locks in on the capacitance field of the fluid passing through and accurately detects changes resulting from lower levels, different fluids, or changes of phase, to initiate an alarm, the company says.

The monitor has UL, CAN/CSA, IEC and CE approvals and an Intrinsically Safe option for use in hazardous areas.
