LibertyCES has documented Radar / Ultrasonic / Hydrostatic Level Transmitter in Water/Aqueous service, including potable water, river water and sea water. Wetted materials to confirm: PVDF and ceramic, PP/EPDM or PVDF/FKM, Stainless DIN 1.4571 and PPS. Documented models include GF Signet 2250 Hydrostatic and 2260 Ultrasonic. Compatibility depends on exact concentration, temperature and duty cycle, so confirm with a free spec review.

On a real LibertyCES bulk-fertilizer job, ultrasonic level sensors failed in vapor-heavy tank conditions — dense chemical vapor caused sensor drop-outs and false readings — the exact failure mode GF Signet's own Application Matrix predicts by rating 2260/2270 ultrasonic '-' (Not Recommended) for dense surface foam and high surface agitation.
