Products Description
This product is a magnetic float sensor device, specially developed for liquid depth detection. It uses high-performance imported chips, advanced circuit processing and compensation technology to convert buoyancy changes into linear current/voltage to calculate liquid level depth data, real-time detection, accurate, and uses a 128*64 high-definition display LCD template to display the status of various parameters. The built-in Bluetooth version of the WiFi module connects to the APP to achieve remote visualization, alarm, early warning notification, and multiple smart devices, switch linkage and other operations. The device is powerful, reliable, fast, and easy to install. It is widely used in water plants, refineries, sewage treatment plants, swimming pools, water tanks, light industry, and other fields that require liquid measurement.
Applications
● Fire water level
● River water level
● Household Water Tank
● Factory Pool
Product Features
● The LCD high-definition display liquid depth/percentage in real time, it can also realize remote APP monitoring and control integration through WIFI.
● It adopts sensor chip of high-performance measurement probe, which is stable and reliable. The probe uses a stainless steel floating rod to prevent water and corrosion.
● It is not limited by temperature and can be used for liquid level in high temperature, low temperature, high viscosity, crystalline and easy-to-clog situations.
● Built-in 2-way relay which will be auto triggered when when the upper and lower limit settings exceed the set alarm value.
● The maximum length of the detection rod is 300cm, and measuring range can be adjusted by APP. It is resistant to vibration,impact, and radio frequency interference.
● 120db ultra-high decibel siren sound. When the changes is beyond the set value, the siren will be sounded immediately. The APP will push the alarm information to the user mobile phone in real time. The APP can share notifications with multiple people.
