WESAN WPV A E

ELECTRONIC METER | WOLTMAN

Meter for measuring heavily fluctuating flow rates.

• Electronic sensor control for recording flow rate
• Lithium battery, lifetime up to 12 years
• Optical ZVEI interface equipped as standard
• Adjustable reading date for billing
• Rotatable integrator for main meter
• Single-line 7-digit display for easy meter reading
• Ideal design of housing and housing cover prevents sedimentation, stagnant water and air pockets
• No measuring errors in the switch-over range
• In order to secure a safe switch-over the WESAN WPV A E needs a minimum ingoing pressure of 0.6 bar
