Non-Invasive Point Level Measurement for High Pressure Applications
The US-HPR ultrasonic level switch from ABM is the ideal solution for tanks with very thick walls (>2″) and high pressure liquid level application (>10,000 PSI) that benefits from non-invasive operation. Typical installations for the switch include high pressure vessels (i.e. compressors), and detection of liquid-solid interface.
The switch can be installed on magnetic metallic tanks using a magnet mounting flange or on non-magnetic metallic tanks using 1″ ratchet strap with mounting flange. Applications with waves and turbulence don’t affect the switch operation. The switch works with any liquids, and can also detect a liquid-solid interface. Complementary communication software can perform calibration.

Switch Operation
The Ultrasonic Level Switch emits a short burst of ultrasonic energy. The energy is coupled through a matching material to the tank causing the tank to vibrate. The tank vibrations are detected and analysed by the Switch. Based on the vibration patterns the Switch is able to detect the presence or absence of liquid inside the tank, and directly opposite the Switch. When the liquid inside the tank is below the switch point of the Switch, the Switch’s relay will be in the energized state referred to as the Normally Open (N.O) state (connecting the relay common to the relay normally open connector). When the liquid inside the tank is above the detection zone of the Switch, the relay will be in the non-energized state referred to as the Normally Closed (N.C) state (connecting the relay common to the relay normally close connector).
