Installation and Operating Instructions

4.1  Safety instructions

 

Look out for sharp edges (pipes, 

fl

 anges).

 

Installation and deinstallation should only be carried out by 

quali

fi

 ed technical personnel.

 

Mounting and dismounting may only be carried out without 

pressure in the heating or cooling system.

 

After installation a hydraulic pressure test should be carried out 

using cold water to check for leaks.

 

For safe operation, the instrument must be used only under the 

stated operating conditions (see section 15: Technical Data). 

In addition, the guarantee only applies if the allowed operating 

conditions have been adhered to.

 

The security seals may not be damaged, otherwise the guaran-

tee is no longer valid.

 

Protection against lightning is not guaranteed; lightning protec-

tion must be implemented at the installation site.

Ultrasonic Meter is designed for the 

measurement of heat and cooling energy. The connected 

fl

 ow sen-

sor must be installed in the return 

fl

 ow. Optionally, the meter can be 

set in the factory to measure 

fl

 ow volume in the forward 

fl

 ow (state 

when ordering – not for cooling meters!)

.

The instrument has an optical interface for read-out and parameteri-

zation. Optionally, the instrument can be equipped at the factory with 

an M-bus interface, up to two pulse outputs (for energy and volume) 

or alternatively with two pulse inputs. It is also possible to power the 

instrument using a power pack (not available in combination with 

M-bus power supply.)

4.2  General information on the fl ow sensor

 

Be careful not to pick up the 

fl

 ow sensor on the plastic housing. 

Always pick up and carry the sensor on the threaded or 

fl

 anged 

connections.

 

All cables must be laid at a minimum distance of 20 cm to high-

voltage current cables.

 

If more than one sensor is being installed in a unit, care must 

be taken to be sure that all the meters have the same installati-

on conditions.

 

Overpressure must be applied in order to avoid cavitation in the 

complete measurement range; this means at least 1 bar up to 

qp and approx. 3 bar at overload qs (speci

fi

 cations for approx. 

80°C).

 

The 

fl

 ow sensor left the factory in conformance with all ap-

plicable safety regulations. Calibration, maintenance, repairs 

and the exchange of parts may only be carried out by quali

fi

 ed 

technical personnel who are familiar with the dangers involved. 

Further technical support can be provided by the manufacturer 

upon request. Veri

fi

 cation seals on the 

fl

 ow sensor may not be 

damaged or removed – otherwise the guarantee and veri

fi

 ca-

tion of the instrument no longer apply! 

4.3  Technical data of the fl ow sensor

 

Environmental class A (EN1434), for indoor installation 

 

Mechanical class M1*)

 

Electromagnetic class E1*)

General Information

All details and speci

fi

 cations listed in instrument data sheet or in 

these installation and operating instructions must be adhered to: 
• The valid statutory provisions and standards for the application of 

instrument for the measurement of heat energy are: EN1434 parts 

1+6 and the Directive 2004/22/EC with annexes I and MI-004.

• The instrument may only be installed or exchanged by quali

fi

 ed 

and authorized technical personnel.

• The regulations for electrical installations must be adhered to
• The applicable veri

fi

 cation regulations and periods for the country 

in which the instrument is to be installed must be observed.

• The instrument left the factory in conformance with all applicable 

safety regulations.

• The instrument must be stored and transported frost-free. The 

temperature during storage or transport may not fall below 1°C. 

The relative humidity during storage and transport may not be 

more than 80%.

• The instrument identi

fi

 cation and the seals required for veri

fi

 cation 

of the instrument must not be damaged or removed – otherwise 

the guarantee and veri

fi

 cation of the instrument no longer apply!

• To clean the instrument (only if necessary) use a slightly moist 

(not dripping wet!) cloth.

• To protect against damage and dirt the instrument should only be 

removed from the packaging directly before installation.

• All electrical connections of the instrument must be laid at a 

minimum distance of 50 cm

 to sources of electromagnetic 

interference (switches, controllers, pumps, etc.)

• All instrument connections must be laid at a 

minimum distance 

of 10 cm

 to other current-carrying wires.
