Contador de agua inalámbrico GPRS DN15-300mm
The wireless AMR water meter(GPRS) belong to high-tech products in the smart water meter, using of advanced wireless transmission technology, it transforms metered information of conventional mechanical water meter into electrical signal have it stored by micro-electronics control circuit. It is able to automatically read the metering data via wireless remote network and is also able to transfer the data to the back-office system (data center) after reading the meters.
Todos los contadores estarán garantizados contra defectos de fabricación y materiales durante un periodo de un (1) año a partir de la fecha de aceptación. Los contadores o piezas defectuosos descubiertos dentro de este periodo serán sustituidos sin cargo alguno tras su devolución a HBM Meters.
I. Overview
The wireless AMR water meter(GPRS) belong to high-tech products in the smart water meter, using of advanced wireless transmission technology, it transforms metered information of conventional mechanical water meter into electrical signal have it stored by micro-electronics control circuit. It is able to automatically read the metering data via wireless remote network and is also able to transfer the data to the back-office system (data center) after reading the meters.
Ⅱ. Features
1, Easy to build: no wiring required, easy to install and debug;
2, Low construction cost: no wiring costs, use wireless network,signal stability, fast reading data;
3, Long service life: low power design, real-time standby, battery life ≥ 3 years (upload data once a day)
4, Built-in valve, can remotely transmit data, remote control valve.
2. Relative error
The maximum allowable error is ±5% from the low flow area including the minimum flow rate to the demarcation flow rate (exclusive)
From high flow areas including demarcation flow to overload flow (inclusive) when the water temperature is ≤ 30°The maximum allowable error is ±2%; when the water temperature>30°, the maximum allowable error±3%
3.Operating temperature: Cold water meter: (0.1 ~ 30) °C Hot water meter: (0.1 ~ 90) °C Working pressure：≤1.0MPa
4.Pressure loss：≤0.063MPa
5. Installation Environment: Class B – Fixed Water Meter installed in indoor
6. Electromagnetic Environment: E1 – Residential, Commercial and Light Industry
7. Working current: quiescent current <19uA
8. Flow profile sensitivity level: U10, D5
