3. OPERATING PRINCIPLE
The flow measuring principle is based on ultrasonic measurement method. The ultrasonic signal along the
measuring section moves many times upstream and downstream between the ultrasonic sensors, who alternately
performs transmitter and receiver functions. From the resulting time difference the flow rate is calculated. Measured
flow rate is converted into the pulses quantity that is transferred in output pulse terminal.

exposed to the surface.
•Safety guarantees at installation and service of meter is:
- Reliable insulation of electrical circuits,
- Hermetic fitting of primary flow sensor into the pipeline,
- Reliable fastening of sub-assemblies of heat meter at installation.
Warning! Mounting of the flowmeter is permissible only after ensuring of absence of heat
conveying fluid in the pipeline.

6. INSTALLATION
6.1. Basic requirements
Before installing the device:
- check if all parts listed in the documentation are available,
- check if there are no visible mechanical defects,
- check if there are valid labels of manufacturer and certification authority.
Only qualified personnel may install the equipment, following the requirements listed in this document, in
technical documentation of other system components and in heat meter installation project
It is forbidden to wire signal cables nearby (less than 5 cm) with power cables or cables of other devices.
6.2. Electrical wiring
Factory installed pulse cable
The cable cannot be removed, shortened or extended, if the pulse cable is already installed.
Customer pulse cable
Connection of the customer pulse cable. It is recommended to use copper wire cable with the cross-section
(0.2 ... 0.5) mm2.
By means of tweezers remove a protective knoll from 1 sealant hole of electronic unit. Run the cable
through the hole and anchor with clamp. Use two wire connection methods –connect to the terminals 18 and 19 as
shown in Annex A, Fig.A1.
6.3 Mounting
Mounting of electronic unit
Electronic unit may be installed in heated premises; working ambient temperature shall be not more than
55 ° C. It may not be exposed to direct sunlight.
Electronic unit can be mounted in several different ways:
- Direct mounting on ultrasonic flow sensor housing, turning every 90o(only when the temperature
of the flow does not exceed 90 ° C):
a) On the flow sensor with a thread connection
b) On the flow sensor with flange connection
- Wall mounting:

- Mounting on standard DIN-rail:
 Important: It is forbidden to attach the electronic unit directly to a wall if there is a risk that on walls
can be condensed humidity or temperature of a surface of a wall can fall lower than 5 °. In this case, it
is recommended to attach the calculator so that between it and wall surfaces there were an air gap not
less than 5 cm.
Mounting of flow sensor measuring section
Sizes and mounting dimensions of flow sensors are provided in Annex B.
Requirements for flow sensor installation in pipeline:
- For flow sensors DN15…DN50 no requirements for straight pipeline length in upstream and downstream
directions.
- For flow sensors DN65, DN80 and DN100 necessary straight pipelines lengths are: upstream straight
pipeline length must be not less 5DN and downstream straight pipeline length must be not less 3DN.
Avoid the flow sensor installation near after the pumps which can cause cavitations.
Flow sensor can be mounted in horizontal, vertical or inclined positions in return or flow. Necessary
condition in normal working mode: pipeline must be under pressure and fully filled with heat conveying liquid.
The location and position of the flow sensor must be selected in such a way as to reduce the risk of
accumulation of air bubbles in the zone of ultrasonic sensors (Fig. 6.1).
a) Permissible installation position b) The installation position is prohibited.
(the air bubbles may accumulate)
Fig.6.1. Mounting Position of the flow sensors qp 3,5 m3/h... qp 60 m3/h
The direction of the sensor installation (is indicated with the arrow on the label of flow sensor) must match
with the flow direction in pipeline.
The flange gaskets must match with the pipe diameter. During the installation gasket must be exactly
centred with the centre of the pipe cross-section to avoid sticking out gaskets inside the pipe.
6.4. Sealing after installation
The sensor must be sealed according to p.4.2 to ensure that after the installation, it is not possibility of
dismantle, remove or altering the meter without evident damage on the meter or the seal.
Mounting seal:
After installation the case and cover of the electronic unit (see Annex C, fig.C1, pos.3) are sealed with two
hanged seals of heat supplier.
