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. Upstream and downstream the meter install an appropriate water flow interception and regulation devices suitable to allow inspection and maintenance of the meter, control of the water flow and eventual sealing of the system.

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).

It is mandatory to comply with the prescribed type of assembly (return pipe\supply pipe). Always refer to what is on the meter menu 3 level 06. The figure below refers to a standard version of the device installation (mounting on return pipe) and positioned horizontally.

All versions of the thermal energy meter can be installed both horizontally and vertically. For a better performance it is preferable, however, the horizontal installation with the turbine axis perpendicular to the ground and the reading mechanism facing upwards.

This position is not suggested for cooling meters and in cases where moisture can enter the electronic casing due to condensation (e.g. during an interruption of the plant in the summer)

TEMPERATURE SENSOR INSTALLATION

The thermal energy meter is equipped with two digital probes that comply with the MID 2014/32/directive and the EN1434 standard.

For a correct installation, always proceed in compliance with the directives prescribed by current regulations.

In the standard version (e.g mounting on return pipe), the return probe is already incorporated inside the brass case. The supply probe must be installed in a ball valve or in a socket mounted on the flow pipe and complies with the requirements of the sensor itself.
Vice versa, the version for installation on the inlet pipe the probe inserted inside the brass case will be the flow, the return probe will need to be installed in a valve or a socket on the return pipe.

Before installing the ‘free’ probe (the one not inserted in the meter case), it is necessary to intercept the flow (close the ball valve or the appropriate shutters).

INSTALLATION IN A SOCKET

1. Screw the socket in the pipe
2. Insert the temperature sensor
3. Tighten the screw

BALL VALVE INSTALLATION

1. Insert the probe into the threaded nut
2. Insert the closing pin
3. Unscrew the valve closing screw, and place the seal
4. Insert the probe by screwing it on the thread

For a correct temperature measurement, the tip of the probe must be in the center of the pipe. In addition, the axis of the probe must be perpendicular to the pipe axis (see figure).
The temperature sensor must be sealed when the installation is complete.

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.

In residential systems, usually with two pipes systems, the measurement of thermal energy takes place on a single section both in heating and cooling cycle.
The picture below reports a typical connection diagram (installation on return pipe):
