The SOR model 722 and 712 dual point with self-test ultrasonic level switches are the perfect choice when you need an instrument with two set points for high and low alarms or pump control.

The 722 model features a self-test mechanism so you can be certain the device is still working even if there is no liquid present.  It’s a cost-effective, electronic instrument with no moving parts. Preventive maintenance is limited to an annual visual inspection and can be accomplished by a technician with basic electrical skills (wiring).

  • No additional set-up or calibration required
  • Set points can be linked to provide “pump-logic”
  • Pressure from vacuum to 2000 psi, temperature from -40°F to 250°F
  • Relay and current shift (8/16 mA) output available
  • 316SS, Alloy 20, and Hastelloy-C sensors
