Prothermo NMT81 measures the average temperature of a medium and can optionally identify the water level. 

With an optional 2 m long capacitance sensor, the water level is measured continuously delivering current water level information at any time.

With its highly precise average temperature measurement, the NMT81 is perfectly suitable for custody transfer and inventory monitoring together with tank gauging such as Proservo NMS80, NMS81, NMS83, Micropilot NMR81, NMR84 and TankSideMonitor NRF81.
