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 a downflow riser, the MTK dry pipe measuring insert in the downflow housing is supplied. This water meter is ideal for all downdraft riser installation points and makes verification replacement a breeze.
Compared to the 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 MTK-FA-N can be retrofitted with a pulse encoder (Reed) for remote data reading.
