Product Features
The principle of guided waves is almost not limited by any process conditions. For example, it is not sensitive to dust and steam conditions, and even environments with large amounts of steam do not affect its measurement accuracy
The probe can be truncated, so customers can adjust the length on site according to their range needs, making it very flexible to use.  
The advanced design principles determine that its measurement accuracy is not affected by medium fluctuations, density, or changes in dielectric constant (as long as it reaches the specified dielectric constant)
Suitable for working conditions where material hanging may occur, even if a large amount of medium is adsorbed on the probe and container wall, it will not have any impact on the measurement results
Verification can be completed without filling the tank
Two wire and four wire connection methods are available for selection
Can be used for liquid level, material level, and interface measurement
Can provide a bypass design or directly cooperate with glass or magnetic flip column level gauges to form a comprehensive measurement solution

Selection Tips
If you need to purchase a guided wave radar level gauge, you need to carefully determine the following parameters: measuring medium, temperature, pressure, range, connection method, output method, whether it needs to be displayed on site, and whether it needs to be explosion-proof.
