White cylindrical ultrasonic level sensor with NPT fitting

Flowline

Flowline Ultrasonic Level Switch Universal PFA

SKU CH-3WF0-CETZJ

Ultrasonic point-level sensor for corrosive liquids with PFA body, NPT connection, NEMA 6 rating, analog and digital outputs, operating up to 150 psi and 176 Degrees F

  • Product typePoint Level Sensor
  • Ultrasonic point-level sensing for corrosive liquids
  • PFA body resists aggressive media up to 150 psi
  • Operates horizontally or vertically in harsh environments
  • NEMA 6 enclosure protects against water ingress
  • Dual analog and digital outputs for flexible control

Ultrasonic Level Switch for Corrosive Liquids

The Flowline ultrasonic level switch provides point-level detection for corrosive liquid media. Its PFA body material resists chemical attack in harsh process environments. The unit mounts in horizontal or vertical orientations to suit tank geometry. It is suited for plant engineers specifying reliable level control.

Connection Size and Pressure Rating

The sensor installs via a 3/4 inch NPT connection into the process vessel. It withstands a maximum operating pressure of 150 psi during normal service. This single specification confirms mechanical compatibility with the piping system. Buyers needing a different thread size or higher pressure rating must select another model.

Temperature Limit and Enclosure Protection

Media temperature must not exceed 176 degrees Fahrenheit for accurate switching performance. The NEMA 6 rated enclosure protects internal electronics against temporary submersion and directed water jets. One analog and one digital output transmit level status to the control system. The switch operates without a float stem, reducing mechanical wear.

Questions about this item

What does the ±1 mm accuracy mean when the switch is installed in a tank?

The sensor will trigger within one millimetre of the true liquid level, giving repeatable point-level detection for process control.

How does the 3/4 in NPT connection limit installation options?

The 3/4 inch NPT thread requires a matching female port; it cannot be used with flanged, tri-clamp or metric fittings without an adapter.

What clearance is needed to mount the switch horizontally or vertically?

The PFA body and 1-inch float need enough tank opening for the 4 1/2 inch float length plus wiring space, and the NEMA 6 rating allows submersion.
