Sensus WPD FS Hot Water Meters 130°C

The Sensus WP-Dynamic FS (WP-QF) is the flanged, high-pressure member of the WP-Dynamic hot-water range — a Woltmann/turbine flow sensor for measuring hot water up to 130 °C (overloadable to 150 °C) in heating systems operating at elevated pressures. Rated PN25/40, it serves as a flow sensor for heat meters where the standard PN16 hot-water meter is not suitable, while retaining the powder-coated body, sealed rotatable register and interchangeable measuring element of the WP-Dynamic platform.

Features & Specifications

  • Flanged turbine (Woltmann) flow sensor for hot water up to 130 °C, overloadable to 150 °C

  • High-pressure rating PN25/PN40 (25/40 bar)

  • Size range DN40–DN300 (WP-QF datasheet DN50–DN300; for DN50–DN150 the MeiStream PN40 body applies)

  • Sealed register, water-proof to IP67, rotatable through 360°

  • Up to three pulsers may be fitted without breaking the meter seal

  • Interchangeable measuring element; high overload capability

  • Performance to PTB-A22 / ISO 4064; suitable as a flow sensor for heat meters

  • Powder coating for maximum corrosion protection; not affected by external magnetic fields

  • Installation with 3 × DN straight pipe upstream; no abrupt restrictions downstream

  • ISO 9001 manufacture
