| Datasheet

Application:

Multi-jet impeller meter with pulse output contact for control, metering or remote display of flow rate


Features:
  • Especially low head loss and extended measuring range
  • Records very small amounts of water consumption
  • Withstands high load for short time periods
  • Maximum long-term accuracy
  • Forward and return metering
  • Strainer insert in inlet connection for cleaning without damaging the seal
  • Measuring data better than specified by calibration regulations
  • Easiliy replaceable pulse contact
  • Pulse contact with screw connection (standard version) or cable 2 m
  • Max. contact load 24 V (SELV) 0.2 A
