Water meters MTKD-FA

Multi-jet dry dial water meter in a downpipe housing
MTKD-FA is a multi-jet dry dial meter for downstreaming pipes.
The proven MTK water meters dry dial measuring insert is available in a downpipe housing for vertical installation positions with a downward flow direction and makes calibration replacement uncomplicated.
The MTKD-FA is equipped with the new ZENNER D-register and is available in two versions:
MTKD-M-FA with 8-digit rollers register and modulator disc for non-reactive scanning for radio (wireless M-bus, LPWAN), M-bus or pulse. MTKD-N-FA 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.
