Multi-parameter IoT sensor (4-in-1 pressure temperature liquid level) Product Name: Multi parameter IoT Sensor (Four in One Pressure, Temperature, and Liquid Level)
Product model: XT-TLQ-04
Product specifications: L140mm * W140mm * H940mm
Product use: Mainly used to monitor the temperature, height, and pressure of the liquid inside the container. Through 4G IoT technology, key data is uploaded to the customer server, and customers can understand the pressure situation of the container on site on their computer or mobile terminal. Can be used for monitoring ton barrels, water tanks, oil tanks, sprinkler trucks, etc.
