Compound water meter WPVM
Compound water meter with cartridge meter as secondary meter for use in drinking water distribution and industrial applications
The WPVM was designed to record fluctuating flows, for use in drinking water distribution and industrial applications. The main meter is based on the proven Woltman parallel technology. As a secondary meter a multi-jet wet dial meter is used, with which even small flows can be reliably recorded.
All the materials used in the drinking water sector correspond to the[nbsp] required standards, directives and current Drinking Water Ordinance (German environmental ministry recommendation of hygienically suitable metal materials for drinking water, KTW guidelines and DVGW worksheet W270).
