Large Caliber Contactless IC Card Cold Water Meter ISM-011

General Introduction
SIM-010 Large Caliber Contactless IC Card Cold Water Meter has various calibers. They are mostly used for industry water supply and suitable for large caliber pipes. It is separate structure, which is composed of controller, waterproof electric ball valve and transmitting water meter.

Controller Models

Controller is powered by 220V AC and storage battery, 220V AC will charge up storage battery at ordinary time and when power cut, storage battery will supply power for more than 3 days and when the voltage of storage battery is lower and not enough for power supply, water meter will close valve automatically.

Main Performances
1. Waterproof electric ball valve, made from UPVC industrial material, erosion and aging resistance.
2. Powered by 220V AC and storage battery. If AC is failure, storage battery can go into operation. When the storage battery is below capacity, valve will close automatically to stop water supply.
3. When remaining water volume is 200m3, controller will alarm by sound, and then swipe the user card can release the alarm. When it is 100 m3, controller will alarm by stopping water supply and also alarm , to remind the user to buy water, and after swiping the user card, it will resume water supply.
4. Timing operation of valve, which can effectively prevent locking with rust due to long time idle state.
