Submersible Wireless Liquid Level Sensor for Water Management

DAQ-GP-TLL4G wireless liquid level sensor terminal is a wireless liquid level measurement product launched by Shanghai Shucai IoT Technology Co., Ltd. The principle is to use a Wheatstone bridge on a diffused silicon wafer . The measured medium (gas or liquid) applies pressure to change the resistance value of the bridge wall (piezoresistive effect), generating a differential voltage signal. This signal is converted into a standard analog signal or digital signal corresponding to the range by a dedicated amplifier , which can then be converted into the pressure corresponding to the liquid level of the measured liquid. Since there is a certain coefficient proportional relationship between different liquid level depths and liquid pressure , the water level of the measured liquid can be obtained by using this coefficient proportional relationship. This product has strong anti-interference, overload and shock resistance, small temperature drift, high stability, and high measurement accuracy. It is an ideal liquid level measurement instrument in the field of industrial automation .

The sensor terminal supports 4G/WiFi/LoRa and other communication methods by default , as well as MQTT, HTTP and other communication methods. It can overcome the wireless communication obstruction caused by the special on-site environment, greatly simplifying on-site deployment time and reducing construction costs .
