Application:

Meter for measuring heavily fluctuating flow rate


Features:
  • Main meter with calibratable and exchangeable measuring insert
  • Horizontal installation
  • Bypass meter on the right or left
  • 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
  • In order to secure a safe switch-over the WESAN WPV A needs a minimum ingoing pressure of 0.6 bar
