Measuring System
The Proservo NMS 5/7 is an intelligent tank gauge for high accuracy liquid level measurement employing the
latest microprocessor technology. As well as level measurement, Proservo NMS 5/7 can determine the inter-
faces between three liquids, specific gravity of these liquids and tank bottom. To enable accurate volume cal-
culation or simply for indication, Proservo NMS 5/7 will accept an input from either an average temperature
probe NMT 53x series (via twisted pair cables, HART protocol) or via spot temperature element (via 3 wire Pt.
100 RTD signal). Once installed, all calibration and operating functions can be made via the user friendly
Matrix program and touch sensitive keypad. Tank side monitoring and operation can be performed by the
Promonitor NRF 560.
