Following instructions refer to the ultrasonic ow sensor.

The regulations on the use of energy meters must be observed! The

meter installation is only to be performed by an installation and/

or electrical contractor using personnel trained in the installation

and use of electrical equipment and familiar with the Low Voltage

Directive.

- Medium: water, as per AGFW Instruction Sheet FW510.If water

additives are used (e.g. corrosion protection), the user must

make sure that the corrosion resistance is adequate.

- The specied medium temperature

is 5 ... 90°C/105°C/130°C(150°C)

- The temperature range depends on variant and nominal size

- The exact temperature range is shown on the type plate

- The sealed variant is to be used if condensation is expected

- The specied operating/ambient conditions are:

5…55 °C; max. 93% rel. humidity

- IP54 (heating) / IP65 (cooling, heat/cooling)

- Ambient temperatures below 35 °C ensures typical battery

lifetime

This installation guide is intended for trained personnel and

does not contain any basic working steps.

If the ow sensor is insulated with the pipeline,

the calculator must be accessible.

Safety Note

The seal on the ow sensor must not be damaged!

A damaged seal will result in immediate invalidation

of the factory warranty and verication.

The relevant ESD regulations (electrostatic discharge)must be

observed.

No liability is accepted for damage (especially to electronic circuits)

resulting from failure to comply with the ESD regulations.

Instruction SONO 1500 CT 3.0 Installation of flow sensor Depending on the application (heat or cooling meter), the flow sensor is installed in the forward or return pipe of the system. The flow sensor must be installed so that the direction of flow corresponds to the direction of the arrow on the sensor. Calming sections are not needed before or after the energy meter, but calming sections of 3xDN are recommended before the meter.

Instruction SONO 1500 CT 4.0 Power supply SONO 1500 CT can be powered from lithium battery (11 years lifetime) or from external voltage supply (standard). Battery 3.0 V DC lithium battery with 11 years of battery lifetime is fitted in flow sensor. The battery is not to be charged, replaced or shortcircuited. Ambient temperatures below 35°C ensure the typical life of the battery. A battery powered version of SONO 1500 CT allows medium temperature up to 90°C.
