Technical data

standards and regulations Technical data is included in the specification sheets for each type of water meter. Water meters comply with the following standards and regulations:

1. Directive 2014/32/EU of 26.02.2014 on the harmonisation of the laws of the Member States relating to making the measuring instruments available on the market.
2. The Act of 13.04.2016 on the systems of conformity assessment and market surveillance
3. PN-EN-14154 standards harmonised with a directive 2004/22/EC of the European parliament and the European council of 31 march 2004. MID (Measuring Instruments Directive)
4. PN-ISO 4064 – Measurement of water flow in conduits. Water meters for cold potable water.
5. Ordinance of the Minister of Development of 2.06.2016 on requirements for measurement instruments,.
6. Ordinance of the Minister of Economy of 07.01.2008 on legally required metrological control of measurement instruments. 

Manufactured water meters may have other installation lengths than the ones provided in PN-EN14154 standard. It is so because of specific user needs. The basic requirements regarding the installation of water meters can be found in standards: PN-B- 10720 - Water supply systems Installation of water meter sets in water supply systems. Requirements and testing upon receipt. PN-EN-14154 – 2: Installation and operating conditions

Description of proper water meter operation

MWN (WPH-01) water meter consists of a body, measurement unit and a counting mechanism. A water jet pushes the rotor placed in the measurement unit. The rotor is placed coaxially to the body channel and via a work and worm-wheel system it drives the magnet placed on the axle. A magnet in the wet part of the water meter coupled with the counter magnet in the dry part of the water meter. Water meter gauges and wheels which sum the volume of the measured water are driven by a gear system.

MP-01 (WS-01) water meter consists of a body, measurement unit and a counting mechanism. A water jet pushes the rotor placed in the measurement unit. The rotor is placed perpendicularly (vertically) to the body channel. A magnet in the wet part of the water meter coupled with the counter magnet in the dry part of the water meter. Water meter gauges and wheels which sum the volume of the measured water are driven by a gear system.

Compound water meter MWN/JS or JM or WS or WM. consists of a main water meter of MWN type described above and an auxiliary water meter. A JS type vane wheel water meter or a single jet wet type vane wheel JM water meter, or a multi jet dry type vane wheel WS water meter, or a multi jet wet type vane wheel WM water meter may be installed as an auxiliary water meter. The division of flow through the auxiliary water meter (small flows) or the main water meter (large flows), regarding the flow volume, is controlled by the spring switching valve. Action of this valve is automatic and does not require any external energy source. As a result of the valve operation the measurement ranges of main and auxiliary water meters penetrate each other, similarly the compound water meter has a very large measurement range, from the minimum flow volume of the auxiliary water meter to the maximum jet flow volume of the main water meter.

The value of water meter pulse in basic design (factory) for a contact transmitter (NK).
