NML-310 Liquid Level Transducer

Brand: KOBOLD Instruments, Inc

KOBOLD NML-310 liquid level transducers are synthetic (nonmetallic wetted parts) float level transducers suitable for level measurement in vessels of up to 108 inches in height.

Floats are made from PTFE. Tubes are 316 stainless steel, clad with PFA or PTFE. Flanges and fittings are available in polyethylene (PE), polypropylene (PP), PVC and PTFE.

The use of 2" NPT fitting or flange accommodates the diameter of the float and enables installation of the Model NML-310 level transducer from the top of the vessel or mounting bracket without removing the float.

Each plastic NML-310 transducer comes with a NEMA 4 housing.

Available outputs include variable resistance or analog level signals.
