Flow meters is latest  state-of-art  microprocessor based electromagnetic type, having flanged connections with integral sensor, transmitter, processor & indicator suitable for measurement of water flow. Water contains silt and sand particles. Meters are lined with Polyurethane (PU) liners. GPRS router have communication capabilities of different protocol with RS 485 device and console serial part should support 11 bit serial device data for data acquisition from piezometer to control server. Mobile operator provide independent static IP address for M2M gateway at our own server Automatic re-establishment of communication in case of temporary failure of wireless link. In built security mechanism to prevent unauthorized enter to the system. The meter data transfer unit is battery operated manufactured as per ISO 4064: 2014 Standards and shall have IP 68 ingress protection. accuracy better than or equal to 2%.
