HYDROCAL-M4 •
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
EN
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, Wireless M-BUS and
LoraWan network 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 potentially dangerous batteries, handle them with caution and do not disperse the
components 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 (1-6) and Directive 2014/32/EC (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 4: Troubleshooting
Mount only the newly supplied gaskets (gaskets should not get in the pipeline). Seals provided on site must be fit for purpose and comply with local guidelines and directives. B METERS disclaim all liability for consequential damage resulting from the use of third-party gaskets, such as corrosion of sealing surfaces and threads. -
Page 5: Before Installation
3. Installation BEFORE INSTALLATION Before the thermal energy meter installation make sure that the two ends of the inlet and outlet pipe are perfectly aligned, clean them with the utmost care. Moreover, make sure there is a suitable filter placed at the inlet and that clean and undamaged gaskets are inserted on both sides. The thermal energy meters must be installed as specified by the CEN-TR 13582 regulation. -
