  • Accurate detection within ±1 mm tolerance
  • Handles pressures up to 150 psi
  • Operates in media up to 176 °F
  • Flexible horizontal or vertical mounting options

Ultrasonic Point Level Sensor

The Flowline ultrasonic level switch is a point level sensor built for corrosive liquid monitoring. A polypropylene body and NPT connection resist chemical attack while delivering ±1 mm accuracy. It operates at up to 150 psi and 176 Degrees F in horizontal or vertical mounting orientations. The NEMA 6 enclosure protects internal electronics in wet environments.

Suits corrosive tanks, not continuous reading

This switch suits plant engineers who need a single discrete or analog alarm point on vessels holding aggressive media. The universal mount works on side walls or tops without a stem. Buyers who require continuous level measurement or a longer insertion depth should look at a different sensor type. The float diameter and fixed length limit use to compatible tank openings.

±1 mm switching accuracy

The defining specification is the ±1 mm repeatability at the switch point. This precision determines whether the sensor will reliably trigger pumps, valves or alarms at the exact liquid height your process demands. Verify that this tolerance matches your control system requirements before installation.

Questions about this item

How can I verify the Flowline ultrasonic level switch is operating correctly after installation?

Check that the analog and digital outputs respond when the liquid reaches the 1-inch float at the 4 1/2-inch stem length, and confirm the NEMA 6 enclosure remains sealed.

What comes with the Flowline ultrasonic level switch and what must be purchased separately?

The sensor includes a polypropylene body with 3/4-inch NPT connection, 1-inch float, and 4 1/2-inch stem; wiring, mounting hardware, and a compatible controller are not included.

Which Flowline ultrasonic level switch version should I choose for my application?

Select this model when you need a polypropylene point level sensor rated for 150 psi and 176 °F media temperature with both analog and digital outputs for corrosive liquids.
