About Nivus

NIVUS GmbH, established in Eppingen of Germany, is a renowned company with many years of experience in the development and production of measuring equipment and technology. It was founded in 1967 and since then has been continuously developing systems for measuring flow, levels and pressures. Nivus is constantly finding new solutions and improvements, thanks to the fact that they always follow the trends the sector.

One of the most significant moments in the history of the company is the presentation of ultrasonic (cross) correlation (2000), which for the first time enabled the measurement of the actual flow profile, with a spatial allocation in the range of millimeters.

To date, in addition to its headquarters in Germany, 8 more international branches have been opened and they do business with another 40 distributors worldwide.

Nivus measuring equipment uses the latest generation technologies with user friendly interfaces and simple connectivity in line with the latest trends (WIFI connection with smartphones, laptop, tablet and / or other devices, i.e., the direct transmission of measured data via GPRS).

The cross-correlation method enables the determination of the actual velocity distribution within the flow profile from which the flow is calculated with a precisely determined medium velocity (vmed)

Principle of operation of cross-correlation sensor:

  • the sensor continuously scans the particles in the medium
  • particles reflections are stored as images
  • determining TFPI time difference Δt between two pulses as a function of pulse repetition frequency
  • the average velocity of each set (layer) is calculated using: D=c*Δt

Internet application for collecting, reviewing and processing measured data.

All Nivus measuring devices with integrated GPRS module have automatic access to the Nivus WebPortal.

Nivus WebPortal enables monitoring of measuring devices (location, battery, status), alarming and report preparation.

The “Chart” module enables extensive analyzes of each measuring point, as well as comparison of data between several measured locations.
