Ultrasonic Level Sensor 49.2 in Range

The Flowline DS14-01 is a noncontact ultrasonic level sensor built for corrosive or sticky liquids. It mounts via a one-inch NPT connection and uses a PVDF antenna for chemical compatibility. Process engineers and plant operators use it where contact probes would foul or degrade.

49.2 in Range with 2 in Dead Band

The sensor measures levels up to 49.2 inches from the transducer face. A 2-inch dead band means reliable readings start just below the mounting point. Spatial resolution of 0.019 inches and accuracy of 1/8 inch provide fine granularity. The 2-inch beam width at 100 kHz limits use in very narrow vessels or near internal obstructions.

24V AC/DC Loop-Powered Operation

The four-wire output delivers a 4 to 20 mA signal powered from a 24V AC/DC supply. Maximum current draw stays low, so standard DIN-rail supplies are sufficient. Operating pressure is rated to 30 psi and media temperature spans 20 to 140 degrees Fahrenheit. No moving parts means silent operation and minimal maintenance in normal service.

Questions about this item

Will the 1 in NPT connection on the DS14-01 fit the existing 1 in NPT fitting on my current tank?

Yes, the sensor uses a 1 in NPT connection which matches standard 1 in NPT tank fittings for direct installation.

How can I verify the 4 to 20mA output is working correctly after wiring the 4-wire configuration?

Power the sensor with up to 24V AC/DC and measure the output current; it should read 4mA at the 2 in dead band and scale to 20mA at the 49.2 in range.

Does the box include the 24V power supply and wiring needed for the 4-wire output setup?

The sensor ships as the PVDF ultrasonic unit only; a 24V AC/DC power source and 4-wire cabling must be sourced separately.
