| Technical Index In Jingyuan IC card intelligent water meter, the wet type multi-jet meter with rotary Vanes which is reliable and mature in this industry is used as the base meter. The meter and the valve Are integrated as a whole and its casing module is made of copper only. The meter is durable and its Measurement is accurate and reliable. The fouling-proof micro-power electric ball valve is used and no Pressure difference occurs. The total length of the meter completely meets the national standard and its Installation, repair and replacement are very easy. Standard Every indicator is in accordance with or prior to Ministry of Construction Standard. CJ/T 133-2001, GB/T778-1996, B/T8802-1998. Basal meters are in accordance with national standard GB/T 778.1-1996 Cold Water Meter Product caliber: DN15mm/DN20mm/DN25mm Measurement accuracy: Grade B Working pressure: Max. Permissible working pressure: 1.0MPa Pressure difference at max. Flow: ¡0.1MPa Pulse collecting Model: Dual-pulse collection Power supply: 3.6V replaceable Li-Thiony| Chloride battery Working conditiions: Medium temperature: 0~40 in case of cold water meter, 30~90 in case of hot water meter Ambient relative humidity: ¡93% Water pressure: ¡1.0 Mpa Main Functions Advance payment function: The water charge shall be prepaid and the supply will be suspended If purchased amount runs out. Alarm function: Low battery, inadequate amount. Limited purchased amount function: Effectively avoid the willful water purchase of the user. Credit function: Automatically read the credited water amount. Multi-range charging function: Calculate the charge at multi-range water rates in combination with Background control system. Auto reading function: Can read the month water comsumption of the late 12 month. Display function: The LCD can display the consumed, remaining and purchased amount And other status information. Abnormal detection function: It can automatically record the strong magnetic field disturbance and Other abnormal conditions. Valve management function: The valve will be regularly actuated once to avoid the abnormal valve open/close due to the fouling accumulated caused by no operation for a long time. Universal card function: A universal card is compatible for water-, power-and gas meters. Heat quantity measurement function: Can sum up the heat quantity of the hot water consumed by the user. (hot water meter-optional).
