WESAN WP

WESAN WP

BULK WATER METER | WOLTMAN

The bulk water meter WESAN WP can be used for measuring the flow in supply lines with high flow at low pressure loss.

  • Calibratable and exchangeable measuring insert
  • For horizontal and vertical installation
  • Sealed measuring insert for better accuracy
  • Hydraulic bearing relief
  • Wear-resistant plastic bearing
  • Encapsulated counter of glass/copper IP 68
  • Complete head unit with counter and sensors can be rotated by 350° for easier reading
  • Integrated measurement outputs as standard
  • Sensors for remote readout (digital) and flow measurement (analogue) can be retrofitted on site without affecting calibration
