WESAN WS

BULK WATER METER | WOLTMAN

For measuring of fluctuating flows in the utility sector.

  • Calibratable and exchangeable measuring insert
  • For horizontal installation
  • Outstanding long-term accuracy even under extreme loads
  • Extended measuring range better than metrological class
  • Complete head unit with counter and sensors can be rotated by 350° for easier reading
  • Encapsulated counter of glass/copper IP 68
  • Integrated measurement outputs as standard
  • Sensors for remote readout (digital) and flow measurement (analogue) can be retrofitted on site without affecting calibration
