26G Phase Difference Radar Level Gauge Wireless Transmission 4G/NB-IoT/433MHz

The phase difference radar level gauge is an instrument that measures liquid level by using the phase difference of radar waves.

The phase difference radar level gauge determines the liquid level height by measuring the phase difference between the transmitted and received radar signals. The radar emits electromagnetic waves, which are reflected by the surface of the medium and then received by the radar. The phase difference between the transmitted and received signals is in a certain proportional relationship with the distance to the surface of the medium. By calculating the phase difference, the distance between the radar installation position and the material surface can be obtained, and then the liquid level height can be determined.

• High Precision: It can achieve millimeter-level measurement accuracy of ±2mm/±1mm.
• Strong Anti-interference Ability: Some phase-difference radar level gauges are equipped with advanced signal processing technology, capable of intelligent echo analysis, and can resist various interferences caused by foam, agitation, floating objects, etc.
• Non-contact Measurement: Measurement is conducted by emitting and receiving electromagnetic waves, without direct contact with the liquid being measured, thus avoiding possible contamination or damage caused by physical contact in traditional level gauges.
• Wide Application Range: It is suitable for measuring various liquid media, including crude oil, slurry, volatile liquids, etc., and can operate stably in harsh environments such as vacuum, high temperature, and high pressure.

Phase difference radar level gauges can be used for hydrological measurements in rivers, lakes, reservoirs, etc., as well as water level monitoring in river channels, irrigation canals, culverts, flood control, etc. They are also suitable for water level monitoring in urban flood control, waterlogging, underground pipe networks, and monitoring of mountainous area flash floods and other scenarios.
