Water meter MTW-F in a downflow riser for temp. up to 90 °C


For vertical installation in a downdraft riser, a multi-jet dry duct measuring insert is supplied in the downdraft housing. The water meter is ideal for all downdraft riser installation points and makes calibration replacement a breeze.
Compared to a vertically integrated standard water meter, the counter here continues to work in a horizontal position. Due to the associated low bearing load, a higher measurement stability can be achieved during long-term oper

  • Sight glass made of high quality UV-resistant plastic
  • Water meter for vertical water pipes (downflow riser)
  • Horizontal position of the counting mechanism
  • Option MTW-N-F can be retrofitted with a pulse generator for remote data reading.
