GPRS/GSM remote reading water meter

Wireless GPRS/GSM remote reading water meter   

Advantage:

This series of MINSEN water meter uses advanced wireless transmission technology. Through microelectronic control circuits, it converts the pulse signals of traditional mechanical meter into electrical  signals. Then the metering data is transmitted to background platform through GPRS network automatically,  or it can be collected by a wireless handheld unit from outside of the houses and after that downloaded to a computer through USB port.

1. Application:

Measuring the volume of cold potable water passing through the pipeline.
