WESAN WPV A G

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
Encapsulated counter of glass/copper IP 68
Good long-term measuring accuracy
Complete head unit with counter and sensors can be rotated by 350° for easier reading
System compatibility, WESAN WPV A G can be extended with IZAR RADIO (clip on radio module), IZAR PULSE (clip on pulse module) or IZAR M-BUS I (clip on M-Bus module)
In order to secure a safe switch-over the WESAN WPV A G needs a minimum ingoing pressure of 0.6 bar
