Compact residential heat meter, type POLLUCOM F wMBUS, DN15 (1/2"), Qp=1.5 m3/h, Tmax: 150 °C, L=110mm, G 3/4" thread, supply-side installation, with radio module for remote reading PEFBANM1

Modern compact heat meter for heating and cooling systems

The POLLUCOM F wMBus residential heat meter is an advanced measuring device designed for precise monitoring of thermal energy consumption in heating and cooling installations. Thanks to its compact design and wide range of functions, it is ideal for both individual apartments and larger district heating systems - from single premises to complex heat distribution networks.

Advanced radio communication and system integration

The device is equipped with an integrated Wireless M-Bus radio module compliant with the OMS (Open Metering System) edition 4.0.2 standard, which guarantees full compatibility with all remote reading systems operating under this standard. The module supports T1 and C1 modes, enabling both mobile "walk-by" or "drive-by" reading as well as integration with stationary AMR/AMI networks based on OMS.

Communication can be activated in several ways - manually by holding the button for 5 seconds, setting the date, or automatically after reaching a volume of 100 liters. Upon successful activation, a radio communication symbol appears on the LCD display, indicating an active data transmission module.

Precise measurements and advanced analytical functions

The heart of the device is a mechanical single-arm turbine flow transducer with electronic scanning directly at the turbine wheel with a resolution of 30 ml. The system ensures accuracy class 2 m³ according to EN 1434 and a wide measuring range of qi/qp = 1:25, 1:50 or 1:100.

The PT500 temperature transducer with a length of 45 mm and a diameter of 5.2 mm operates in a temperature range of 5...90°C, allowing for use in "6/12°C" cooling systems as well. The entire measuring system is managed by an advanced programmable calculator with an optical IR interface and a fast measurement cycle - temperature, power, and flow updates occur every 4 seconds.

Extensive archiving and configuration capabilities

The system features an LCD display menu containing real-time data (cumulative consumption, instantaneous power), target dates (cumulative energy consumption), an archive (16 months of historical data), service level (maximum values), tariff settings, and parameters protected by a security password, accessible directly in the device without additional peripherals.

The integrated data logger collects information for periods of up to 1200 hours, 120 days, and 120 months, while simultaneously recording up to 500 error events. The tariff system allows for differentiated billing, e.g., according to heating power or heating/cooling mode - all parameters are password-protected directly within the heat meter.
