12. Safety and environmental requirements
12.1 The water/flow meter is a measuring instrument which is safe to use, provided it is installed properly
and operated according to this
Operating Manual.
12.2 Hazards exist during installation, servicing and operation of the product:
a) Mechanical hazards (applicable to water/flow meters):
•
Fall during improper handling;
•
Water leaks, leading to flooding of the product due to improper installation or a water pressure
exceeding the
rated MAP;
b) Thermal hazards (applicable to water meters):
•
Burns from touching the water meter while it is in operation or a leak of hot water.
12.3 The mechanical hazards are reduced by the external shape of the measuring device, which facilitates
handling. Large devices have fixtures for attachment to lifting equipment. The thermal hazards can be
prevented by application of dedicated
guards.
12.4 The installation and servicing of the
water/flow meter requires a suitable location with firm ground
that
will not cause a hazard of falling.
12.5 The water/flow meter
components are not harmful to human health or the environment. All
measurement devices are delivered with hygiene certificates indicating their suitability for use with drinking
water.
12.6 The applied ingress protection rating of the counters (which can be IP65 or IP68) and other design
solutions protect the water/flow meter against the negative effects of water vapour condensation interfering
with the correct reading and operation of transmitter/data modules.
12.7 Classification of environmental conditions
•
Classification of mechanical environmental conditions – class M1, as per the Polish
Regulation of the Minister of Development of 02/06/2016 and Directive 2014/32/EU of the
European Parliament and of the Council of 26 February 2014.
•
Classification of climatic environmental conditions – Class B, as per PN-EN ISO 4064-2:2014
and Directive 2014/32/EU of the European Parliament and of the Council of 26 February
2014.
•
Classification of electromagnetic environment conditions – Class E1 and E2, as per EN ISO
