Hot water meter MTWD-ST-M and MTWD-ST-N

The MTW multi-jet measuring insert is available in a standpipe housing for vertical installation positions with an upwards flow direction.

The MTW multi-jet measuring insert is available in a standpipe housing for vertical installation positions with an upwards flow direction and makes calibration replacement uncomplicated.

The MTWD-ST is equipped with the ZENNER D-register and is available in two versions:

MTWD-M-ST with 8-digit-rollers register and modulator disc for non-reactive scanning for radio (wireless M-bus, LPWAN), M-bus or pulse. MTWD-N-ST with 7- or 8-digit rollers for different pulse values and retrofittable
with mechanic pulser.

In comparison with a vertically installed standard water meter, the register keeps on functioning, even in a horizontal position. Thanks to the resulting decrease in bearing load, a significant improvement in the long-term measuring stability can be achieved.

Applications

  • For the consumption measuring of cold potable water up to 90° C
  • Water meter for standpipe installation

AMR options

  • MTWD-N-ST with pulse output (reed) for remote readout
  • Standard pulse value 10 l/pulse, optional 1 l/pulse available

MTWD-M-ST serially equipped with communication interface for:

  • Electronic pulser
  • Wired M-bus
  • Radio via wireless M-bus
  • Radio via LPWAN (LoRaWAN™, SIGFOX)
