Part name: Flow Meter
Description:
Flowmeters are devices to be connected to water pipes and capable of measuring, through the rotation of an impeller, the flow rate of water flowing through the pipes. The principle of operation is based on an interaction between a magnet fitted on the impeller and a Hall effect sensor mounted on the housing of the flowmeter. Two main families are available: axial flow meter 10.0453.xx; radial flowmeter (paddle wheel) 10.0884.xx. Axial flowmeters can be produced as stand-alone version or integrated on water solenoid valve. Radial flowmeters can be produced as stand-alone version. Custom hydraulic onnections are available for water heaters applications.
General characteristics:
  • Glass filled PA material
  • Food grade (WRAS)
  • Custom hydraulic connections
  • Card-edge electric connection (rast 2.5) or cable
  • Customizable signal by different number of magnets
  • Axial module can be integrated on valve bodies or customer sub assemblies
  • Radial module can be integrated on customer sub assemblies
