Heat meter B_METERS Hydrocal M-3 Dn15 Q=0.6 P (DWZ) — compact DN15 thermal energy meter, Q=0.6 m3/h

The B_METERS Hydrocal M-3 Dn15 Q=0.6 P (DWZ) is a compact DN15 thermal energy (heat) meter designed to measure heat consumption in heating systems. It determines delivered thermal energy by combining volumetric flow measurement with temperature difference readings, providing the data needed for accurate billing and consumption monitoring in residential and small commercial installations. Its small-diameter design and nominal flow Q=0.6 m3/h make it suitable for installations with limited pipe space or low flow demands.

Advantages

The meter offers compact dimensions and a DN15 connection size that simplify installation in tight spaces. By measuring both flow and temperature differential it delivers direct thermal energy readings, reducing the need for separate calculations. The design supports reliable, repeatable measurements at low nominal flow (Q=0.6 m3/h), helping to ensure accurate accounting in single-apartment or small-object heating circuits. The unit is a practical choice where a small, integrated solution is required for monitoring and billing heat consumption.

Suitable for

• Residential apartments and single-family houses
• Small commercial premises and offices
• Individual heating circuits with DN15 piping
• Metering points with low to moderate flow rates (around Q=0.6 m3/h)

Key specifications

• Connection size: DN15 (suitable for 15 mm pipelines)
• Nominal flow rate: Q = 0.6 m3/h
• Measurement principle: volumetric flow combined with temperature difference
• Application: thermal energy (heat) measurement for heating systems
• Typical installation: compact inline mounting on supply or return pipework

How to use

Install the Hydrocal M-3 in the heating circuit according to the direction of flow indicated on the meter body, ensuring secure DN15 connections and appropriate sealing. Connect the temperature sensors or integrated sensors to the designated ports and verify correct orientation and contact. After installation, verify system tightness and perform an initial functional check by running the heating system while observing flow and temperature readings. Use the meter readings to record cumulative thermal energy usage or integrate the meter output into a building management or billing system where applicable.

Usage recommendations

For reliable long-term performance, install the meter in a location protected from freezing, mechanical shock and excessive vibration. Ensure straight pipe runs upstream and downstream where recommended by the manufacturer to minimise flow disturbances. Schedule periodic verification and maintenance according to local metering regulations and good practice to maintain measurement accuracy.
