Perfect flow measurement in full pipelines Insert or clamp-on

The NivuFlow 600 system was developed particularly for flow measurement in full pipes. To meet the highest possible accuracy requirements it is possible to utilise up to 32 velocity paths. There are pipe sensors as well as contactless clamp-on sensors available for the measurement system. It is not necessary to interrupt running processes to install both sensor types. The system is suitable for the detection of flow rates in various liquid media covering a wide range of applications.

Flow measurement systems at the highest technical level

The compact enclosure can be easily integrated into switching cabinets saving space thanks to DIN rail mounting. Moreover, the NivuFlow 600 units are available in a special field enclosure for use in rough environmental conditions.
The transmitter‘s large graphic display allows quick and easy commissioning of the flow metering system. It further-more provides extended diagnostic options and enables in-depth analyses of running processes on site.

The transmitter software was newly developed from scratch. Using future-proof protocols and versatile options for communication and connections opens a wide variety of options to operators when it comes to integrate the instruments into higher systems such as SCADA or process conducting systems.

Typical applications

Hydropower
Leakage monitoring
Irrigation systems (volume distribution and billing)
Inlets and outlets conducting cooling water or circulation systems
Industry: process water, slightly polluted water and more
Comparative measurements
Pump monitoring and verification

The measurement principle

The NivuFlow 600 measurement principle is based on detecting the transit time of ultrasonic signals between two sensors (A and B).
The transit time in flow direction t is shorter than it is against the flow direction t 2.

The difference between both transit times is proportional to the average flow velocity along the measurement path vM .The system calculates the average crosssectional area velocity vA from the path velocity vM and indicates it directly on the display.

Flow in full pipes is calculated by using the general equation of continuity:

Q= A • vA

A= cross-sectional area

v = average flow velocity in cross-sectional area

The Nivu Flow 600 Transmitter

The intuitive one-hand operation and the bright high-resolution colour display allow quick, easy and cost-efficient commissioning on site. Additional input devices or software are not required.
