Compact residential heat meter, type POLLUCOM F wMBUS, DN20 (3/4"), Qp=2.5 m3/h, Tmax: 150 °C, L=130mm, connection GZ1", return line installation, with radio module for remote reading PEFCAJI1

Compact solution for smart energy measurement

The PolluCom F wMBUS residential heat meter is designed for precise monitoring of energy consumption in heating and cooling systems.

The device utilizes a highly precise flow transducer with a nominal flow of 2.5 m³/h, enabling installation on the return of heating/cooling installations while maintaining compact dimensions of 130 mm in length and a GZ1" connection.

Advanced wireless communication wMBUS OMS

The built-in radio module Wireless M-Bus OMS profile A version 5 or profile B version 7 is compliant with the OMS 4.0.2 standard. The module supports T1 communication modes (for stationary networks) and C1 (for mobile readings).

The radio key management system is regulated by Sensus via a customer portal with GDPR and BSI certifications.

Comfortable data reading solutions

The device enables access to measurement data through dedicated DIAVASO software. The system allows for comfortable mobile reading on foot or from a car, significantly simplifying the data collection process without the need for physical access to each device.

The built-in M-Bus interface compliant with EN 1434-3 ensures an unlimited number of readings with a configurable data transmission protocol. Additionally, pulse inputs are available for external water meters (e.g., measuring hot/cold water consumption), as well as an OC-type pulse output (1 kWh/pulse) allowing integration with external totalizing systems.

Operating characteristics and environmental conditions

The heat meter features an accuracy class of 2 or 3 according to EN 1434 and a measurement range qi/qp of 1:25, 1:50, or 1:100. The operating temperature range is 5...105°C, and for cooling systems, it can be extended to -20...105°C using an anti-freeze solution.

The flow transducer operates in a temperature of 5...90°C. The maximum allowable working pressure is 16 bar, and the pressure loss at the nominal flow qp is only 0.21 bar.

The device has an IP54 protection rating, an allowable ambient temperature of 5...55°C, and a battery life of 8 years (under standard configuration without active communication). The built-in data logger records data for periods of up to 1200 hours, 120 days, and 120 months, additionally archiving information on up to 500 events and errors.
