Sunray Meter & Control Technology Co., Ltd.

It's a meters company with its manufacturing center and R&D in China, its overseas marketing department and advanced R&D branch in USA who has been providing its metering total solutions in China and other countries in the fields of measuring electricity, water and gas. We are providing almost very kinds of static electric energy single phase meters, three phase meters, automatic meter reading system (AMR) by means of power line carrier communication (PLC) or by industrial bus commnunications (e.g. RS-485), or by radio wireless communications, We are providing water meters, gas meters, intelligent digital electric power inspecting instruments, digital voltage, current, power, frequency, power factor meters (V,I,P,F,FA) in above mentioned single function or combined multi-functions, Wa are providing electricity, water, gas and heat prepayment meters four in one union system that could also operates for one of four meters independently.
Many kinds of our meters have been exporting to Indian, Pakistan, Bengal, Thailand, Egypt, Kyrgyzstan, Indonesia,etc; and enjoyed high reputation. Our products comply with the standards of IEC and other relative international standards. We can also provide our special design only on our clients own demands.
Our ISO9001 quality system has been approved early in 1999 and has been transformed to the version of ISO9001-2000.
The main product lines of ours are as follows,

AMR(Automatic Meter Reading) SYSTEM
Low voltage AMR system is for residential and industrial meters, high voltage AMR system is for industrial high voltage gateway meters. An AMR system consists of meters with RS-485 or PLC (Power Line Carrier Communication modem built in meters) or wireless radio communicator that is built in meters or in data collectors (depend on system's construction), data concentrator communicated with upper host stations by means of PSTN, GMS, GPRS or CDMA

IC CARD PREPAYMENT METERS SYSTEM FOR ELECTRICITY METERS, WATER METERS, GAS MET
