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:
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.
