Nowadays, the water refilling station is mushrooming in many cities, because the demand for cleaner water becomes higher and a lot of people prefer to get their drinking water from these water stations. In order to effectively monitor and manage those equipments, the station manager adopts GT-530, an intelligent SMS alarming controller, to monitor the machine’s operation. GT-530 not only has the burglar-proof system, but also equips with the counter function to help the manager understand their daily business volume and transaction precisely by SMS.
