WESAN WPV A

WESAN WPV A

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
