NivuMaster - Model NM5, NM6, NM9 -Transmitter for Contactless Level Measurement

• Measurement of level, distance, volume, difference and flow
• Alarm output in case of flooded sensor possible
• Pump control saves energy and costs thanks to intelligent pump management
• High measurement reliability through intelligent agitator avoidance
• Connection of maintenance-free, Ex-protected radar and ultrasonic sensors  
• Up to 6 relays and galvanically isolated mA outputs
• Easy echo analysis and setting of parameters using free PC software
• Integrated emergency power switchover
• Easy operation in dialog mode using back-lit graphic display

The NivuMaster series transmitters supply connected R- Series and P-Series sensors, process measurement values and indicate readings. NivuMaster transmitters are ideally suitable for simple control tasks in level measurement applications. Flow measurements in open channel using a Venturi flume or Q/h-relations, on any kind of weir or discharge sills are possible without any problems.

NivuMaster is available with wall mount enclosure, as 19"-plugin or with panel mount enclosure.

The few parameters required for measuring can be entered easily on site in dialog mode thanks to the back-lit display and the integrated keypad. Parameters can be evaluated using the free software “PC Software Suite” and the serial interface of the transmitter.
