GSW7666-F is an electronic-valve controlled water meter with accurate measurement for revenue protection of water utilities. Complying with STS standard and equipped with a Customer Interface Unit(CIU) for inputting recharging tokens & searching for information, it could also link to a Data Concentrator by RF LoRa, with tariff charging & data transmission by AMR(Automatic Meter Reading) system as two main functions.

Main Features

·STS-standard compliant
·20-digit token input by CIU
·Optional brass/plastic meter body
·Pre-programmable low-credit warning

·Non-return valve preventing back-flow
