Water meter MTW / MTW-N / MTWI-N for temperatures 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

The MTW water meter is ideal for demanding measuring tasks with water temperatures up to 90 ° C. The model of a multi-jet dry duct for hot water, thanks to the use of special materials, ensures accurate measurement results at a high temperature limit.
MTW water meters are supplied in the familiar WVG or ZENNER housings adapted to the flow properties. The MTW-I-N version is supplied with a pulse generator for remote reading of data.

The dry-running multi-jet vane meter is equipped with a state-of-the-art transmission.
Since only the impeller is in the water, errors due to the influence of contaminated water on the counting mechanism are eliminated
Sight glass made of high quality UV-resistant plastic
Water meter for horizontal pipelines
Option MTWI-N with pulse output (Reed) for remote data reading system
Standard resolution 10 L / pulse, options 1000 L / pulse, 100 L / pulse, 1 L / pulse
