    Tips: Application of radar level sensor in reservoir water level monitoring

    The reservoir water and rain monitoring system is suitable for the water conservancy management department to remotely monitor the real-time data such as the water level and rainfall of the reservoir. It also supports remote image monitoring, providing accurate and timely on-site information to ensure the appropriate water storage of the reservoir and safe flood season.
    The reservoir water and rain monitoring system has achieved real-time monitoring of the water and rain conditions of the reservoir, realized the information management of the reservoir, and played a major role in protecting people's lives and property safety.

    System composition:
    Radar level sensors, rain gauges, reservoir detection terminals, security cameras, communication devices, etc.


    1. Remote detection
      1. Reservoir distribution location and on-site equipment operation status.
      2. Real-time data such as water level, rainfall, device battery voltage, etc.
    2. Remote monitoring
      1. During GPRS/CDMA communication, it supports timed, over-limit or remote manual photography.
      2. Support video real-time monitoring during optical fiber/ADSL/3G/4G communications.
    3. Automatic alarm
      1. When the water level/rainfall exceeds the limit or the field equipment fails, it will automatically alarm.
      2. Automatically send alarm text messages to the responsible person's mobile phone.
    4. Statistical Analysis
      1. Automatically count the time, day, month and year data reports of water level and rainfall.
      2. Automatically generate process analysis curves such as water level, rainfall, and battery voltage.
    5. Data storage
      1. Two-way storage of historical data between monitoring center server and field terminal.
      2. Field terminals can store historical data records of no less than one year.

    Levs-RD909 and Levs-RD908 cannot reach 200M, and the maximum schedule can only be 70M.
    The use of radar level sensor
    The use of radar level sensor
    I need to use your radar level sensor (RD906) in order to measure the level of chocolate in a chocolate tank that can know how many chocolates used per hour. Does it work for such an application?
    From: Markr | Date: 13/08/2021
    Was this review helpful? Yes No (0/0)
    ATO Responded
    I need to know the following, so I can confirm:
    1. What is the size of the chocolate tank (length*width*height)? Is there any stirring rod inside?
    2. Is this chocolate tank sealed? If it is sealed, what is the pressure and temperature?
    Calibration certificate for ultrasonic level sensor
    Is it possible to get the calibration certificate of your radar level sensor?
