Water meter MTW-F in a downflow riser 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 a downdraft riser, a multi-jet dry duct measuring insert is supplied in the downdraft housing. The water meter is ideal for all downdraft riser installation points and makes calibration replacement a breeze.
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 oper
