The new WATERFLUX 3070 battery powered water meter

Duisburg,  February 26, 2009: KROHNE introduces a new measuring instrument: The WATERFLUX 3070 is an electromagnetic water meter for applications in the water and standard applications wastewater industry. It has a very long battery life of 15 years, making it especially suitable for applications where no power connection is available. The meter also has the option of a GSM module for remote transmission of measurement data and status information.


The new WATERFLUX 3070 offers the user some unique benefits that comparable solutions lack: Thanks to extremely short inlets and outlets, the WATERFLUX  can be installed in very narrow wells and chambers. The meter is highly accurate and being a magnetic-inductive meter, it is superior to mechanical water meters in terms of pressure loss and long-term stability. For large diameters, the WATERFLUX 3070 has a significant price advantage compared to the lifetime cost of mechanical meters which require filters and rectifiers as well as maintenance and cleaning.

The heart of the WATERFLUX is the measuring tube with a rectangular cross section, which offers several advantages: The coils are arranged so that a strong, homogeneous magnetic field is formed and the measurement is thus independent of flow profile. In addition, this allows for extremely short inlets and outlets. The optimized thickness of the metering eddy currents are minimized and allow for highly accurate measurement (± 0.2%). The tube itself is high-pressure stable; it is made of metal with a coating of Rilsan®, which is approved for potable water.

For the operation of an electromagnetic water meter, electrical energy is needed. However, in many cases, the remote location of the meter makes connection to the electricity grid impossible.  KROHNE have overcome this issue, by giving the WATERFLUX 3070 a battery life of up to 15 years until the battery has to be changed. This means it is maintenance-free during the lifetime of the battery. Its long lifetime is due to its unique sensor design, and the very low power consumption of the components within the meter.  Due to this modern technology, the power consumption is lower by a factor of 5000 compared to a conventional electromagnetic flowmeter.

If no power supply system is available, often the connection to the PLC is also not available. Therefore, the user at water sources, wells or network transfer is reliant on remote data transmission. For the WATERFLUX 3070, a Datalogger and GSM transmitter as a compact module are available.

The Data Logger stores all data, including peak flow and low flow during the night. This information is then transmitted by the GSM network to the next radio mast and from there via satellite to a server that the user can access.

As well as providing accurate flow measurement, the WATERFLUX 3070 can also indicate the charge conditions of the battery as well as the draining of the tube. The WATERFLUX 3070 meets the requirements for custody transfer according to OIML R-49 and MI-001.

The device is available in sizes from DN 25 to DN 600. WATERFLUX is also available in combination with the well known signal converters IFC 100 and IFC 300, enabling the application and benefits of the unique sensor design in those industries where there is mains power at hand.
