WESAN WPV G

WOLTMAN METER

Meter for measuring heavily fluctuating flow rates.

Calibratable and exchangeable measuring insert in one unit, suitable for calibration comprising: measuring insert as main meter, switch-over valve, measuring capsule as bypass meter
Ideal design of housing and housing cover prevents sedimentation, stagnant water and air pockets
Bypass line integrated in housing cover. No risk of sedimentation or corrosion.
No measuring errors in the switch-over range
Measuring capsule as bypass meter and non-return valve easily replaced on site
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 G can be extended with IZAR RADIO (clip on radio module) or IZAR PULSE (clip on pulse module)
In order to secure a safe switch-over the WESAN WPV G needs a minimum ingoing pressure of 0.6 bar
