Multi Jet LCD Display Prepaid Water Meters With CIU Keypad
LCD Display Prepaid Water Meters Long Battery Life Shut Off When Credit Finishes
The CA568-S is the model number of Calin multi-jet prepaid water meter. It is STS prepayment standard compliant and certified. The meter works with a motor driven valve which turns off when credit finishes or any tamper is detected. Calin prepaid water meter sustains well in grit particle, not clean water environment with steady metrology accuracy and durable life span in severe working scenarios. The meter operates with a keypad CIU in radio link with the meter. This split setup is designed to prevent tamper and theft by installing meters out of customers' reach but the customer can check their usage, balance on the CIU mounted in their house.
