Wireless valve control water meter has the function with remote valve-control, including remote switch valve, magnetic attack switch valve, effect of battery under-voltage on valve control, auto-closing function of arrears.
Valve control function description
1) Remote valve opening.
After receiving the wireless valve opening command, the module returns the confirmation information of the received command.
2) Remote shut off valve.
After receiving the wireless valve command, the module receives the confirmation information of the received command. After the operation of the closing valve, the information of the closing valve is returned.
3) Magnetic attack switching valve.
When the two reed (Holzer) closed (low level output) at the same time, module reported that the magnetic attack alarm, and close the valve, when magnetic attack disappeared after a period of time (according to the set value), set to expect the valve opening state, the valve is no longer open automatically if more than 4 times of interference within 24 hours. You need to contact the meter reader, on-site or remote open valve by RF.
4) Influence of under voltage of battery on valve control.
When the main battery is under pressure, the open valve operation can not be carried out, except valve closing operation. The valve can be opened only after cleaning the abnormal or replacing the battery.
5) Automatic shut off valve function under arrears.
If the prepayment function and overdraft shutdown function are enabled, the module closes the valve automatically when the condition of the overdraft shut-off valve is met. To recharge after the success, if you can open the valve (table with the main battery not under pressure, no arrears, not in the magnetic attack, not to be disassembled, not leak alarm, the valve in the open state), will automatically open the valve operation module.
1) Signal acquisition system
It adopts high-quality Hall element and alternate working mode, which is equivalent to bistable mode, which can effectively prevent measurement errors caused by vibration.
