Water meter for measuring the flow and volume of warm water with a temperature up to 90C in the closed-circuit system with the full flow of the flux, and on the maximum working pressure up to 16 bar (PN16). Suitable for installation in the horizontal hoses (pipelines) with the counter directed upwards (H) and in vertical or horizontal hoses with the counter directed sidewards (V). Water meters SMART+ in standard version are equipped with low eight-barrel counter (IP65), antimagnetic protection SN+, brass housing and they are adapted to operation in the systems of remote data transfer (AMR).
Features and advantages:
- 1/2" or 3/4" male thread BSP with possibility of removing adaptor and switch to 3/4" or 1" male BSP thread;
- Maximum flow rate: 1,6m3/h or 4m3/h;
- Resistant to strong external magnetic field;
- Pre-equipped for installation of: radio module for communication in the Wireless M-Bus, impulse module and M-Bus module;
- Readings reliability fulfils the newest metrological requirements of MID;
- Easy reading of the water meter counter;
- Hermetic counter (with increased tightness) resistant to steaming;
- Counter mechanism with blockade against multiple rotating, at rotation angle more than 360deg;
- Protection against mechanical tampering;
- Protection limiting the results of water freezing;
- Outlet port of water meter housing suitable for optional installation of a return valve;
- Double-sided rotor bearing.
Water meters comply with the following standards and regulations:
1. MID directive 2004/22/EC of 31.03.2004 on measuring instruments.
2. 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).
3. PN-ISO 4064 Measurement of water flow in conduits. Water meters for cold potable water.
4. Ordinance of the Minister of Economy of 18.12.2006 on basic requirements for measurement instruments, as amended.
5. 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-EN-14154 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.
