⚠ What you need for a complete, working meter
The SensoStar C is the calculator only. It cannot measure anything on its own. A working cooling 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 cooling meter calculator is the chilled-water version of the SensoStar C: pair it with a pulse-output flow sensor (FlowStar U, Woltmann or other) and a Pt500 temperature sensor pair to meter cooling energy in HVAC and district cooling systems. It stores monthly values, supports M-Bus or wireless M-Bus radio, and is factory-configured for your flow sensor pulse value.
Key Features:
Cooling meter calculator (PTB cooling approval) for combined meters
Large easy-to-read LCD display with 15 monthly values
Temperature measuring cycle 60 s standard; 30 s or 2 s (mains) optional
Battery lifetime 10 years (standard cycle)
Optical interface; M-Bus or wireless M-Bus radio module options
Pt500 2-wire temperature sensor inputs
Compatible with all common pulse-output flow sensors
Technical Specifications:
Pulse value options: 1 / 2.5 / 10 / 25 / 100 / 250 / 1000 / 2500 litres per pulse
Temperature sensors: Pt500, 2-wire (order UTS / AGFW sensor pair separately)
Interfaces: optical; module slot, M-Bus or wireless M-Bus 868 MHz depending on model
Options at extra cost: LoRaWAN or Modbus module, pulse inputs/outputs, heat and cooling programming
Mounting: return flow; adhesive seal included
