| Datasheet

Application:

For extracting water from underground and stand hydrants.


Features:
  • Calibratable and exchangeable measuring insert
  • For horizontal or vertical installation
  • Outstanding long-term accuracy through hydraulic bearing relief
  • 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
  • Up to two different digital outputs and one analogue output simultaneously
  • Version thread or solid coupling
