Field of application
Prothermo NMT81 measures the average temperature of a medium and can optionally identify the water level. With an optional 2m 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.
For precision average temperature and water bottom measurement
Process connection: Flanges from 1-1/4“
Temperature: -40 to +60°C (-40 to +140°F)
Measuring distance: 100m (328.08ft)
Total accuracy: ± 0.032°C(±0.06°F) with 5pt. temperature calibration
Conversion (transmitter) accuracy: ±0.025 °C (0.045 °F)
Sensor accuracy: ±0.02 °C (0.036 °F)
