The multi-user meter module is a new generation of intelligent remote transmission module developed by our professional technical team after years of intensive research. This module is a water meter communication module with ultra-small size and low power consumption. TTL wired communication is used to connect to the LoRa wireless collection terminal to form up to 16 meters to share a multi-user collection terminal. This method not only solves the problem of trouble in construction and wiring, but also reduces the cost of the wireless module of each meter, and has the advantages of wired meters and wireless meters.
Features
Remote meter reading
Can realize remote meter reading;
Sampling
Can realize a variety of sampling methods, such as reed switch, Hall, etc., with high measurement accuracy;
Attack shut-off
It has the function of preventing external electric and magnetic attacks. When the sample is attacked by external electric or magnetic, the meter can automatically close the valve;
Remote control valve
With remote valve control function, can realize pre-paid and post-paid functions;
In place detection
With switch detection function. When the normally open contact is closed in place, the meter switch valve is in place, and the valve operation can be stopped immediately;
Valve failure detection
Automatically determine whether the valve limit switch works normally, and at the same time, the valve can be opened and closed normally even if the limit switch fails;
Reed switch failure detection
When a sampling reed switch fails, the meter will upload a reed switch fault prompt, and the meter can still accurately measure;
Automatic lookup address
It can automatically obtain the remote communication address of each meter.
