Бесконтактные IC карт Анти-капельная счетчик воды (Ду15)

General Introduction Contactless IC Card Antidrip Water Meter is a kind of high accuracy water meter and can measure water volume even water drops or leaks from taps. It can avoid intended or unconsciously waste of water resource. Its start flow of is 2L/h, which absolutely meets the demand of National Standard of Grade B Water Meter and higher than the standard. Characteristics 1. Measurement of water volume when water flow exceeds 2L/h 2. One household with one water meter and use water meter by unique IC card 3. Prepaid for used water volume 4. Ideally suitable for commercial and industrial water supply 5. Electric ball valve to guarantee good performance of water meter, rust proof, block proof, lower pressure loss and power consumption, suitable for harsh environment. 6. Totally sealed, no outside circuits, waterproof and can work normally even if put into water for hours. 7. Anti-attack of strong electricity or magnetism 8. Technique of micropower to warrant working current less than 4.5μA 9. Having all the advanced technologies of prepaid cold water meter Technique Specifications Caliber (DN) 15mm (1/2") 20mm (3/4") 25mm ( 1") Accuracy Level Grade BMeasure Unit 0.1m3Overflow Rate 3m3/h 5m3/h 7m3/h Common Flow Rate 1.5m3/h 2.5m3/h 3.5m3/h Demarcation Flow Rate 0.12m3/h 0.2m3/h 0.3m3/h Minimum Flow Rate 0.03m3/h 0.05m3/h 0.07m3/h Minimum Reading 0.0001m3Maximum Reading 99999m3Alarm Volume 50m3 /2m3 Working Temperature 0-40 Celsius(cold water meter) 0-90 Celsius(hot water meter) Working Pressure ≤1.0MpaMaterial CopperWeight 1.4Kg 1.7Kg 2.5Kg Model FS-F---wet copper base meter, horizontal installation, cold water, DN15/20/25 FS-FT---wet iron base meter, horizontal installation, cold water, DN15/20
