⚠ What you need for a complete, working meter
The Woltmann is the flow meter only. On its own it measures volume but cannot calculate energy. A working heat or cooling metering point needs three parts:
Flow meter – this product, sized to your pipe.
SensoStar C calculator – works out the kWh and carries the M-Bus or wireless M-Bus communication.
Pt500 temperature sensor pair – measures flow and return temperature.
Choose parts 2 and 3 from the dropdowns above, or pick the "I already have one" option if you are only replacing the flow meter. We programme the calculator to match this flow meter’s litres-per-pulse before despatch, so there is nothing to set up on site.
Description:
Engelmann Woltmann flow meters are mechanical large-flow sensors for combined heat and cooling meters in commercial and district heating systems. The robust flanged PN16 bodies cover DN50 to DN150 and deliver a galvanically isolated pulse output for the SensoStar C or other calculators. WP models install horizontally or vertically; WS models are for horizontal mounting.
Key Features:
Mechanical Woltmann flow measurement, MID heat approval
PN16 flanged connection, DN50 - DN150
Galvanically isolated pulse output (100 or 1000 litres per pulse)
WP type: horizontal or vertical installation; WS type: horizontal installation
Temperature range 0 - 120 °C
3 m control line for flexible mounting
Technical Specifications:
Sizes: qp 15 to qp 200 m³/h, DN50 to DN150
