Telemetering water level station, integrated water level station, telemetering water level gauge

The water level telemetering station is mainly used for monitoring of canals and reservoirs, groundwater level and groundwater level monitoring, monitoring data transmission through GPRS/GSM, SMS to Beidou satellite monitoring platform.

1. main functions
1.1 gauge (optional free float type water level gauge, pressure type water level gauge, ultrasonic level gauge, radar type water level gauge, bubble type water level gauge, etc. optional) by incremental control, timing control mechanism of the two kinds of data transmission, incremental threshold, the timing cycle can be configured.
1.2 has a large capacity of FLASH storage, rainfall data can be stored for more than 3 years.
1.3 with GPRS/SMS, and short distance wireless communication etc.. In support of the multi center operation mode, telemetry stations can send data to up to 5 central stations, each of which can have two communication channels and backup each other.
1.5 supports three kinds of data communication modes: self reporting, self reporting, acknowledgement and response, and three communication modes can be mixed networking.
1.6 support power down, sleep, permanent online three power management mode.
1.7 support remote wakeup, response center command. Stand dormant in the detection, Center for data collection, terminal ready to wake up any time to read or modify the data recording monitoring station configuration information etc..
1.8 if the need can be equipped with a rainfall sensor.
1.9 increase Beidou satellite communication mode if necessary.
