Passive photoelectric direct reading water meter

Photoelectric water meter is original data acquisiton methodological meter.it's a new encoding technology,the typical outstanding features are no error of reading and no battery needed ,and instant power supply offered by concentrator one reading (directly or remotely).this technology can be applied to all kinds of EMI® current water meter series ,for instance,single jet,multi jet ,woltman,dry dial,wet dia.

Photoelectric remote valve control and reading water meter

Photoelectric remote valve control and reading water meter belongs to one type of EMI high-tech remote water meters and this series of meters has adopted the most advanced M-Bus transmission technology ,tranferred measurement information of traditional mechanical meters into electronic data through a microelectronic control circuit and upload the water status measurement results to the data acquisition unit through a RS485 transmission module,the data acquisition unit can have a remote communication network through a wire or wirless module,directly deliver data in a handheld data acquisition unit to computer terminals and achieve information exchange for the purpose of meter reading modernization .in the meantimethe water supply valve also can be controlled to realize remote control or water supply of specific users can be shut down,opened or opened with a certain percentage of control.
