MNK/MTK
The ZENNER house meter is a multi-jet vane meter. Dry and wet meters for cold water (MTK/MNK, up to 50°C) and dry meters for hot water (MTW, up to 100°C). Wet passes are available for both downstream (ST) and upstream applications, as well as with rollers in a protective capsule.
In addition to the basic version, meters of the following modifications are supplied to Russia:
For vertical installation in upflow pipes, the MTW dry pipe measuring insert is supplied in the upflow pipe housing. The water meter is ideal for all installation points on upflow pipes and makes verification replacement a simple procedure.
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 operation. Option MTW-ST-N can be retrofitted with a pulse generator for remote data reading.
