PolluStat® Thermal Energy Meter

Available in these Regions:

Description

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.

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

Benefits to you

  • 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

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.
  • M-Bus 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.
