Water meter MTW-ST in a riser with an upward flow for temp. up to 90 °C

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:

MTK-N/MTW-N counters are prepared for pulse output (convenient for step-by-step integration of already installed and operating devices into a single network for remote information reading).
After installing the impulse cover on the prepared counter, at any time the devices become "impulse"; MTKI-N/MTWIN, a standard version of MTWI is also available, with a pre-installed cable.
The letters AM stand for anti-magnetic design. Since neither in Europe nor in Russia there is a single approved Standard for checking water meters for anti-magneticness, we check our devices according to the method approved in South America (Brazil).

Overview

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.
