WESAN WPV A (phased out)

Bulk Water Meter | Woltman

Meter for measuring heavily fluctuating flow rates.

Ideal design of housing and housing cover prevents sedimentation, stagnant water and air pockets
No measuring errors in the switch-over range
Good long-term measuring accuracy
Complete head unit with counter and sensors can be rotated by 350° for easier reading
Main meter and bypass meter are prepared for connection of two reed switch and one opto transmitter
In order to secure a safe switch-over the WESAN WPV A needs a minimum ingoing pressure of 0.6 bar
