WESAN WP G

WOLTMAN METER

Application

WESAN WP G is a bulk water meter designed for measuring volumes of cold water (up to 50°C) in supply lines with high flow at low pressure loss.
Modular, WESAN WP G DN50 to DN300 can be fitted at any time with an IZAR clip-on module converting it into a communicating meter ready for mobile or fixed network (radio/wired) reading.
The measuring chamber can be replaced without removing the meter from the pipe.
