Overview

Compact Thermal Energy Meter for Cooling/Heating

The compact PolluStat ultrasonic meter measures energy consumption in heating or cooling circuits. Thanks to its high-precision flow sensor, the application range stretches from district heating stations to consumption billing for individual apartments. It is equipped with a large comprehensive LCD with programmable screens.

Product Features
  • With a detachable calculator unit for installation sites with limited space with approx. 0.85 m connection cable
  • Storage of flow rate, power and temperature, as well as the respective maximum values of the last 15 months via radio, additional 15 half-monthly values via the display
  • Modular on-site equipable solution for different communication interfaces offers more flexibility and lower storage costs
  • Standard installation in the “lower temperature pipe” (aka outlet) can be changed to “higher temperature pipe” (aka inlet pipe) installation if necessary on-site, as long as the energy consumption measurement total is below <10kWh
  • Separate 230V or 24V mains power supply module available
  • MID approval in class 2 per EN 1434 for arbitrary installation (also overhead)
  • Temperature range of the flow sensor:
    • Heating meter 15 – 90 °C (Also as variant 15 – 130 °C)
    • Hybrid meter 15 – 90 °C (Also as variant 15 – 120 °C)
    • Cooling meter 5 – 50 °C
  • Optical data interface (M-Bus protocol) as standard
  • Tariff registry: 2 individually customizable registers
  • Freely selectable annual cut-off date
  • 15 monthly values via radio
  • 15 monthly and 15 half-monthly values via the display
  • 24 monthly and semi- monthly values via optical interface or M-Bus
  • PT1000 temperature sensor:
    • Length 45 mm / diameter 5.2 mm, cable length 1.5 m
    • Length 50 mm with locking sleeves at 85 and 100 mm / diameter 6.0 mm, cable length 3 m

The following modules for remote readout and data communication are available as options and can be retrofitted:

  • Wireless M-Bus
  • M-Bus per EN 1434-3 with arbitrary readout frequency, the values update every 2 min.
  • Wireless M-Bus and 3 pulse inputs for consumption meters with remote meter pulse output
  • M-Bus per EN 1434-3 and 3 pulse inputs for consumption meters with remote meter pulse output
  • Single and double Pulse output
  • Modbus (Q1/2021) IEC 61158

Specifications:

For electronic remote reading of the meters and connection to building automation systems, a series of optional modules are available for the PolluStat series, which can be installed in the factory or retrofitted at any time:

Wireless M-Bus (radio)
A wireless M-Bus interface for walk-by and stationary readout in accordance with Open Metering Standard (OMS). 868 MHz frequency with the freely selectable modes S1, T1 and C1. Encryption modes 5 and 7 can also be selected per OMS 4.0.2.

M-Bus
For cable-connected data readout via a 2-wire cable with reverse polarity protection per EN13757. Suitable for monitoring, building automation, or connection to an existing M-Bus network. Unlimited number of readouts. (Data update rate 120 s, with external power supply operation 2 s.)

Remote meter pulse
Potential-free pulse output for connection to various interrogation devices.

Wireless M-Bus (radio) with three inputs for external consumption meters
This option allows the connection of up to three external consumption meters, e.g. an electricity meter, a cold and a hot water meter. Reed contact or open collector pulse can be connected. The pulse value can be adjusted with the optical head and by suitable software.
