Battery powered water counter
Krohne has launched the Waterflux 3070, an electromagnetic water counter for standard applications in the water and wastewater industry.
Its battery life of 15 years makes the meter suitable 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.
Its measuring tube 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 narrow wells and chambers.
The optimised thickness of the metering eddy currents are minimised 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.
According to Krohne, the Waterflux 3070 is superior to mechanical water meters in terms of pressure loss and long term stability. 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 has attempted to overcome this issue by giving the Waterflux 3070 a battery life of up to 15 years. The long battery life is due to the sensor design and the low power consumption of the components within the counter.
As well as providing flow measurement, it can also indicate the charge conditions of the battery as well as the draining of the tube. It 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.
