.
.
Install metering devices (water meters or flow meters) and pressure transmitters in the valve wells
next to each hydrant.
Metering devices are used to measure the single water intake and instantaneous, cumulative flow
of water users.
The pressure transmitter is used to collect pipe pressure data, which can detect whether there is water in the pipe and the amount of water pressure to determine whether the smart hydrant can be used
normally.
The metering device and pressure transmitter are equipped with transmission interfaces, which can transmit data
through standard 4~20mA, RS485, pulse and other signals.
An IP68-rated RTU device, namely the DATA-7601 micropower acquisition terminal
, needs to be installed in the valve well.
The device has a variety of transmitter signal acquisition interfaces, as well as 433M wireless transmission function, which can be used for two-way data transmission
with the DATA-6241 swipe metering water intake device on the well.
