Operating and Installation Instruction
1. Introduction
The HYDROCAL-M4 is a compact thermal energy meter that measures the energy consumption of heating and
cooling systems. The meter allows to measure the thermal energy passing into a hydraulic circuit used for
heating and\or for cooling, it also lets the acquisition through external module, of the volume measured by up
to 2 device (water, heat, gas, electricity, HCA) equipped with pulse emitter. The meter can also be connected to a
consumption reading network based on the wired M-BUS (IR-MB-PULSE), Wireless M-BUS and LoraWan protocols.
The first configuration chosen during installation (supply or return pipe) can't be modified!
The top calculation/electronic unit must not be separated from the bottom brass case.
This meter contains dangerous batteries, handle it with caution and do not disperse in the environment.
The installation must be carried out by qualified personnel only. The manufacturer doesn't assume any
responsibility for improper installation or damages caused by third parties.
STORAGE CONDITIONS
The product must be stored in a dry place at temperatures between -20 °C and +70 °C (even during transport).
The duration of the storage should not exceed 1 year.
Combined heating or cooling meters are precision devices and must be protected from shock and vibration.
GENERAL INFORMATION
• Before proceeding with the installation and configuration of the product, carefully read the instructions in
this manual. For further technical clarification, please contact Customer Service.
• Installation should be carried out exclusively by qualified personnel.
• The reference standard for the instrument is EN 1434 and Directive 2014/32/EU (Annex MI-004).
• Any tampering of the meter or removal of the seals will void the warranty provided.
• For proper energy accounting, always respect the mounting type prescribed (inlet pipe installation/ return
pipe installation).
• The configuration of installation version and unit of measurement can be done with the buttons or an
Android device with NFC connectivity.
• Respect the installation point (input or output) of the instrument.

- Page 2 For more information visit the website www.bmeters.com. Dispose of replaced devices and defective components in accordance with current environmental regulations.
- Page 3 If transmission network interfaces are used, especially when cables are routed outside the building, use increased protection against electrical interference. Rinse the pipes thoroughly before installing the meter. For a proper installation the direction of the arrow on the lower brass body must match the direction of the flow. Avoid collecting air bubbles in the meter during the installation process.
- Page 4 Attention should be paid to the direction of flow. Install the thermal energy meter so that the passage of water takes place in the direction indicated by the arrow in relief on the brass body and respecting the prescribed position. To ensure proper measurement, make sure that there is no air inside the pipe and that the flow is clean and free of debris (potentially harmful to the meter turbine).
- Page 5 The temperature sensor must be sealed when the installation is complete. 4. Functionality The HYDROCAL-M4 is equipped with dedicated sections for the measurement of thermal energy of a heating/ cooling circuit and the volume measurement given by the domestic hot and cold-water meters. The meter is suitable for domestic applications with two-pipe systems, in a thermal power plant or any other compatible application.
