The NML-308 is a miniature, synthetic float-level transducer suitable for level measurement in vessels up to 48 in. tall. The floats 
are made from PTFE and the tubes are 316 stainless steel. The fittings are available in PTFE, polyethylene (PE), polypropylene (PP) or polyvinyl chloride (PVC). The transmitted level signal is converted to a 4–20-mA analog signal via a remotely mounted DIN rail transmitter. — Kobold Instruments Inc., Pittsburgh, Pa.
