DeltaPoint (DPL Series)

Resistance Welding Water Flow Monitor

Stand alone water circuit E-Stop unit

Flow Range: .4 – 12 GPM (1.9 – 45.4 LPM)

Max Pressure: 190 PSI (13 BAR)

DeltaPoint detects leaks from cap loss, hose burst or inadvertent shutoff.

Monitoring robotic cells, pedestal welders or multiple work cells.

Water is shut down to stop the leak and a signal is sent to the controller.

The flow sensors have no moving parts to be affected by entrained contaminants.

The only mechanical parts are the shut off and check valves.

For a robot or PLC controlled water flow monitoring unit, see DeltaPoint Jr.
