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.
