the water meter well and additionally the water meter and its equipment should be installed far
enough from the well bottom.
2. In the location of installation, the water meter connot be at risk of being hit or be subjected to
vibrations caused by other devices in the vicinity or subjected to high ambient air temperature,
contamination, flooding and corrosive action of the surroumdings. Temperature in the installation
location should not be lower than 4 °C. The water meter should be protected from influence of such
hydraulic phenomena such as cavitation or hydrodynamic water hammering.
3. Before and after the water meter provide the valves in order to cut off the water supply if there is
need for deinstallation or repair. Use valves which can entirely reveal the cross – section of a water
pipe.
4. In case of expected water contamination during time of operation, install a filter or a setting tank
between a valve and a strraight pipe section and before the water meter.
5. For an installation of a water meter which does not cause strain in the body it is recommended to
use compensative connectors installed at the output.
6. The pipe in the installaton lacation should be shaped so that there is no possibillity for an air pocket
to be created in the water meter. Water meter has to be entirely filled with water, so the water pipe
after the water meter cannot decline. (Illustration 5: Water meter installation).
7. Water meter should mot be under risk of excessive strain caused by pipelines and equipment. If
necessary, install it on a pedestal or in a grip. What is more, the pipes connecting on the inlet and
outlet side should be adequately fastened, so that no part of the system is dislocated by the water
when the water meter is deinstalled or disconnected from one side.
8. During installing a meter in the water network, observe the correct water meter orientation according
to the design: for horizontal, vertical and diagonal operation. (Ilustration 6: Sample permitted
installation positions).
