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.
Before installing the flow sensor, rinse the pipe well; mount the spacer for this purpose.
The flange gaskets must match with the pipe diameter. During the installation gasket must be exactly
centered with the center of the pipe cross-section to avoid sticking out gaskets inside the pipe.
It is forbidden to wire flow sensor signal cables nearby (less than 5 cm) with power cables or cables of
other devices.
5.3.3. Mounting of temperature sensors
Temperature sensors are mounted by head upwards, is perpendicular to the pipe axis or inclined by 45 °
angle on fluid flow direction so that the sensing element has been inserted in medium at least up to the pipe axis or
beyond (as shown in Annex C).
For meters with flow sensor joining G3 / 4 ', G1, and G1 ¼' – one temperature sensor is mounted in the
flow sensor housing.
It is forbidden to wire signal cables of temperature sensors nearby (less than 5 cm) with power cables or
cables of other devices.
5.4. Setting up the jumpers (J)
The connector J is on the calculator plate between the temperature sensors and pulse input / output
connection terminals (Figure A1). Joining or leaving open the connector contacts, you can choose the normal or
verification (test) mode, activate the pulse inputs or outputs:
Fig. 6.1. Definition of jumpers
5.5. Verification of installation and set-up
After installing the heat meter, let measured fluid flow through the flow sensor. Measured parameter values
should be indicated on the display, if the heat meter (calculating unit, flow and temperature sensors) is installed
correctly. If measured parameter values are not displayed correctly, it is necessary to verify the installation.
5.6. Sealing after installation
The meter 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:
-
Hanging seal on the junction between upper and lower part of the housing of the calculator (see Annex
C, Fig.C1)
-
Seals on the protective cover and mounting bolt of temperature sensors (see Annex C, Fig.C3).
- Connection of flow sensor with the pipeline should be sealed in addition.
Jumper is not set (contacts are opened)
