Specifications Dimensions Flow Range How to order
Battery powered electromagnetic water meter
  • Battery driven with very low power consumption for remote locations
  • Easy installation without straight inlet or outlet lengths
  • IP 68 rated signal converter for submersion in flooded chambers
It is ideal for remote locations in the water industry where no power connection is available and provides certainty in case of power failure. The strengths of the KF700W lies in its unique flow sensor construction with a rectangular and reduced cross section and its efficient coil construction. The coils provide a stronger and more homogenous magnetic field, leading to an improved signal to noise ratio. The measurement is therefore independent of the flow profile and measurements are very stable. This results in a very good low flow performance.
Because of the unique WATERFLUX flow sensor design, whereby the mean flow velocity and flow profile are optimised within the rectangular and reduced cross section, the additional uncertainty for upstream disturbances is drastically reduced. The water meter can be installed directly after an elbow or reducer in the pipe without straight inlet or outlet lengths. A substantial reduction of inlet and outlet sections means smaller measurement pits.

Another major benefit of the rectangular sensor construction is the very low power consumption of the signal converter. It has a long battery lifetime of up to 15 years with two internal batteries and 20 years with an external battery pack.

Highlights
  • Stand alone water meter with battery lifetime up to 6 years
  • Unique rectangular sensor construction results in good low flow performance, a large ratio and very low power consumption
  • Large measuring range. High accuracy at peak flows during the day and at low flows during the night
  • Installation in any position
  • Bi-directional flow measurements
  • Submersible in flooded measurement chambers (IP 68 / NEMA 6P)
  • Special coating for subsurface installation. No need for measurement chambers
  • Rilsan® polymer coating with wide range of drinking water approvals
    Reference electrode. No grounding rings needed
  • Long term reliability and maintenance free. No moving parts, no wear and no obstruction in the flow
  • GSM module for remote data transfer
