⚠ What you need for a complete, working meter
The SensoStar C is the calculator only. It cannot measure anything on its own. A working heat metering point needs three parts:
Flow sensor or flow meter – an Engelmann FlowStar U (DN50–DN300) or Woltmann (DN50–DN150), sized to your pipe. Sold separately.
SensoStar C calculator – this product.
Pt500 temperature sensor pair – add it from the dropdown above, or select "I already have a pair".
Buying the flow sensor and the calculator together? Order from the FlowStar U or Woltmann listing instead and add the calculator there – we then programme the calculator to match the flow sensor’s litres-per-pulse before despatch. Ordering the calculator on its own, please tell us the flow sensor’s litres-per-pulse so we can set the Pulse value to match.
Description:
The Engelmann SensoStar C is a MID-approved heat meter calculator for combined heat meters: pair it with a pulse-output flow sensor (FlowStar U ultrasonic, Woltmann or other) and a Pt500 temperature sensor pair to build a thermal energy meter for any pipe size. It stores monthly values, supports M-Bus or wireless M-Bus radio, and is configured for your flow sensor pulse value at the factory.
