The new WATERFLUX 3070 battery powered water counter
23 September 2009
KROHNE has launched the WATERFLUX 3070, an electromagnetic water counter for standard applications in the water and wastewater industry. Its unique battery life of 15 years makes the meter ideal for applications where no power connection is available. The counter also has the option of a GSM module for remote transmission of measurement data and status information.
The measuring tube of the WATERFLUX 3070 has been designed with a rectangular cross section, which offers several advantages; The coils are arranged so that a strong, homogeneous magnetic field is formed meaning that measurement is independent of flow profile. It also allows for extremely short inlets and outlets, meaning the WATERFLUX can be installed in very narrow wells and chambers. The optimized thickness of the metering eddy currents are minimized so a high measurement accuracy of ± 0.2% can be achieved. The tube itself is high-pressure stable; it is made of cast aluminum with a coating of Rilsan®, which is approved for potable water.
The WATERFLUX 3070 is superior to mechanical water meters in terms of pressure loss and long-term stability. For large diameters, it offers a significant price advantage compared to the lifetime cost of mechanical meters which require filters and flow conditioners as well as maintenance and cleaning.
Ordinarily, for the operation of an electromagnetic water meter, electrical energy is required. However in many cases, the remote location of the meter makes connection to the power grid impossible. KROHNE have overcome this issue by giving the WATERFLUX a battery life of up to 15 years. The long battery life is due to the unique sensor design, and the very low power consumption of the components within the counter. The power consumption is in fact 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 is reliant on remote data transmission. For the WATERFLUX 3070, a Data Logger 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 nearest 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 is available in sizes from DN 25 to DN 600 and meets the requirements for custody transfer according to OIML R-49 and MI-001. For those industries where there is mains power at hand the meter can be used in combination with the well known IFC 100 and IFC 300 signal converters.
