This general purpose two-wire transmitter is available in two configurations for different types of media. The LD31 is designed for relatively clean water, light oils, or diluted chemical media (ground water, ponds, wells) and the LD32 is well-suited for dirty, sludge, or slurry media (sewer or storm pump lift stations, storage and treatment with surface foam or debris where ultrasonic cannot be applied). Both models are corrosion resistant and sturdy.
Also, see our DeltaSpan external side-mount level transmitters.
