The 4G wireless liquid level transmitter adopts the fourth generation of wireless communication technology. Compared with ordinary liquid level meters, it eliminates the trouble of wiring and the need to monitor the site all the time. While greatly improving work efficiency and reducing labor costs, it can also obtain monitoring data anytime and anywhere.
Functional advantages of 4G wireless liquid level transmitter:
The use of submersible liquid level sensor can convert liquid level changes into 4G signals and upload them to the monitoring platform. The platform has an intelligent design and analyzes data through intelligent algorithms. It can automatically judge abnormal situations and issue alarm prompts, which improves the reliability and practicality of use.
Built-in battery power supply, battery life can reach 5 years, and the battery can be replaced.
The LCD display can directly display the current liquid level data, liquid level, signal quality, etc. The staff can directly read the monitoring data on site and can configure it through local buttons.
The storage function can ensure that the device automatically stores data when it is offline to prevent data loss.
High-quality TPU air-conducting cable, can be immersed in water all year round, die-cast alloy aluminum shell, epoxy spray on the surface, used for isolation and anti-corrosion, sealed design, IP68 protection level.
wireless liquid level transmitter has automatic temperature compensation function, which can automatically correct the drift of equipment data with temperature changes, eliminate the influence of temperature on the output signal, and ensure the accuracy of measurement results.
It is small in size and easy to install, and can meet the use needs of various occasions, such as fire trucks, water plants, sewage treatment plants, urban water supply, high-rise pools, wells, water towers, geothermal wells, mines, industrial pools, hydrogeology, reservoirs, rivers, oceans, water circulation, water treatment and other fields.

A pressure transmitter converts the pressure of liquid, gas or steam into a standard electrical signal for PLC, DCS, recorder or control instrument input. It is widely used for pipeline pressure, tank level, flow measurement and process safety monitoring.
Confirm the pressure range, pressure type, medium, temperature, output signal, accuracy, installation thread, electrical connection and environmental requirements. For corrosive media, high temperature or sanitary applications, diaphragm material and sealing structure are especially important.
Gauge pressure transmitters measure pressure relative to atmospheric pressure. Absolute pressure transmitters measure pressure relative to vacuum. Differential pressure transmitters measure the pressure difference between two points and are commonly used for flow, filter and level measurement.
