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
