The microwave pulses emitted by a high-frequency radar level meter are propagated through the antenna, whereas a guided wave radar level meter is propagated through the detection assembly. So, are the installation standards for guided wave radar level meters the same as those for high-frequency radar level meters? Today, we will take a look at the installation standards for guided wave radar level meters.
First point: avoid the tank facilities as far as possible during installation to avoid the detection assembly (steel cables or rods) coming into contact with internal obstacles during the measurement process and affecting the accuracy of the measurement.
The second point: the installation of the detection component as far as possible and the measured media surface to maintain vertical. This way the microwave pulses emitted can reach the specified location and the data can be accurate at a later stage.
The third point: when installed, the radar level meter and the container tank wall need to maintain a certain distance, and away from the inlet and outlet. The feed and discharge ports have a great impact on the accuracy and stability of the radar level meter, so attention must be drawn to them.
The fourth point: If the radar level meter is connected by a thread, its length should not exceed 15mm. Generally speaking, the length of the thread is inversely proportional to the stability of the measurement, i.e. the shorter the thread, the more stable the measurement.
Fifth point: when installing, if the cable is too long, we have to cut off the power supply of the radar level meter, remove the cable, and remove the screws on the weight, from the bottom of the cable to intercept.
Sixth point: when installing, if the radar level meter is installed in the waveguide tube, we should pay attention to fixing the radar probe with insulating brackets to ensure that the probe is concentric with the waveguide tube to avoid improper installation causing vibration and affecting the accuracy of measurement.
The seventh point: when installing the guided wave radar level meter, if the installation vessel process connection surface is made of other materials than metal, either use a metal flange connection or configure a metal plate.
