Level Sensors

NivuCompact Echo Sounder

Part No. NMC

for level and volume measurement

Ultrasonic compact echo sounder in 2- and 3-wire version for non-contact measurement of distance, level, empty space or volume. Parameters can be set directly on site without the need to open the enclosure.

  • Combi unit with sensor and transmitter
  • Measurement range from 0.2 to 10 m
  • Digital echo processing and linearisation
  • Ideal even for battery operation thanks to very short startup and measurement times
  • View echo profiles on PC
  • Unit can be programmed on sit without opening the enclosure
  • Integrated temperature compensation
  • ATEX Approval for Ex-Zone 1

The NivuCompact is a compact echo sounder for non-contact ultrasonic measurement of level, distance, space or volume. NivuCompact can be used wherever reliable non-contact level measurement is required.
Thanks to its very quick startup time of 4 seconds until value output, the NivuCompact is particularly suitable for battery-powered logger operation. High transducer power and tight beam angle in addition with digital echo pro-cessing make the NivuCompact an ideal tool for many "difficult" applications. The integrated display makes programming extremely simple. The NivuCompact is available as 2- or 3-wire version in one unit.
