10 POSSIBLE MALFUNCTIONS AND SUGGESTED REMEDIES
10.1 Possible malfunctions and suggested remedies are given in Table 10.1.
Table 10.1
Malfunction
1. Water does not flow through
the meter
2. Water is flowing through the
Faulty ultrasonic sensors or
meter, but the meter readings
do not increase
10.2 Troubleshooting is carried out in the manufacturer's service center or in a specialised workshop
and the meter is then submitted for verification.
11 TRANSPORTATION AND STORAGE
11.1 Meters in the original manufacturer's packaging can be transported by rail, road, water (except
for sea) and air (in hermetically sealed baggage compartments of the aircraft) with the obligatory
observance of the rules and requirements applicable to these types of transport. Transportation by sea
requires special packaging.
11.2 Packaged meters can be transported at ambient temperatures from –50 to +50 °C and with
100% relative humidity of air at +25 °C.
11.3 During transportation and handling procedures, observe the manipulation signs on the packaging.
The meters should not be exposed to direct atmospheric precipitation.
11.4 The meters must be stored in the manufacturer's packaging in closed, dry premises at ambient
temperature from +5 to +50 °C and with maximum 80% relative humidity of air at +35 °C.
11.5 The air in the premises where the meters are stored should not contain aggressive, caustic and
corrosive fumes.
11.6 Unpacking of meters that are transported in winter must be carried out in a heated room after
keeping them unpacked under normal conditions for 6 hours.
12 DISPOSAL
12.1 At the end of its service life, the product must be disassembled into parts, sorted by material type,
and handed over to a specialised recycling company.
13 MANUFACTURER'S WARRANTY
13.1 The manufacturer guarantees the compliance of the meters with the specified requirements,
provided that the consumer fulfills all the conditions of product storage, transportation, installation
and operation.
13.2 Warranty service life for water meters is five years from the date of sale.
13.3 Meters with mechanical damage and broken seals will not be accepted for warranty maintenance.
13.4 No claims will be accepted if meters are submitted without a completely filled data sheet.
13.5 Send reclamation reports and claim letters to the manufacturing company.

USER MANUAL
1 GENERAL INFORMATION
1.1 Intended use
Ultrasonic water meters JWM are designed for the measurement of cold drinking water or hot water in
hot water systems (according to temperature classes), flowing through a fully filled, closed pipe.
The meters are used for accounting, including commercial accounting, of water consumption in the
industrial and municipal sectors, and for technology processes control.
The meters are not intended for use in any area with a potentially explosive atmosphere.
1.2 Operating conditions:
• Ambient temperature from 5 to 55 °С;
• Relative humidity of air from 0 to 100 %;
• Water temperature depending on the temperature class of the meter:
◦ T30 - from 0.1 to 30 °C;
◦ T50 - from 0.1 to 50 °C;
◦ T70 - from 0.1 to 70 °C;
◦ T90 - from 0.1 to 90 °C;
◦ T30/T70 - from 30 to 70 °C;
◦ T30/T90 - from 30 to 90 °C;
• Water pressure from 0.03 to 1.6 MPa;
• Environmental requirements class – В;
• Environmental and mechanical requirements class – М1;
• Environmental and electromagnetic requirements class – Е2.
1.3 The meters meet the requirements of the Directive 2014/32/EU, Directive 2014/30/EU, Directive
2014/53/EU, Directive 2011/65/EU.
