Customer Service
Due to the complex industrial working environment, the service life of our products depends on the customer's working environment. Under good working conditions, the service life of our products is about 5 years; Under extreme environmental conditions, our products are guaranteed to have a service life of 1 year.
1. The dielectric constant and conductivity of the medium need to be checked based on the measured medium on-site to obtain specific parameter to determine whether to use a conventional radar level meter, a precision radar level meter, or a guided wave radar level meter. If the specific dielectric constant of the tested conductive material/liquid is not less than 4 (which can be viewed on this website), a regular radar level meter can be used. If the specific dielectric constant of the tested conductive material/liquid is lower than 4, a precision or guided wave radar level meter can be used.
2. Consider the measurement accuracy of radar level meters. The accuracy of ordinary radar level meters is much lower than that of precision radar level meters. Choosing between ordinary or precision radar level meters should be based on actual process requirements, otherwise, unnecessary expenses may be incurred.
3. Choose antenna size based on actual material level parameters. Due to differences in antenna size and type, the range width also varies. There are various types of lens antennas for radar level meters, including rod type, horn type, parabolic type, etc. The selection of antenna form can be measured based on the material level parameters.

When installing a radar level meter, avoid the feeding port, feeding curtain, and vortex, as the medium will produce a false echo with a much larger amplitude than the effective echo reflected by the measured liquid level during the injection. Meanwhile, the irregular liquid level caused by vortices can scatter microwave signals, causing attenuation of effective signals, so they should be avoided.
For containers with agitators, the installation position of the radar level meter should not be near the agitator, as irregular vortices will be generated during stirring, which can cause attenuation of the radar signal. At the same time, the blades of the agitator can also cause false echoes of microwave signals, especially when the relative dielectric constant of the measured object is small and the liquid level is low, the impact of the agitator is more severe.
In case of this fault, you can first check whether the power supply and communication cables are normal for troubleshooting.
When communication equipment or components malfunction, it is necessary to debug software, conduct data testing, check sensor status, and repair or replace components.
1. There are many reasons for inaccurate data display. For example, if there is a sudden power outage before the end of data storage, abnormal data display may occur and the liquid level meter needs to be recalibrated. Check the fuse of the device again to see if there is any problem. If there are any problems, replace them promptly.
2. Check the initial setting of the radar level meter and check if the connection method of the display function module plugin is normal. If the output voltage and current are greater than 22mA, it is judged that the display system module of the radar level meter is faulty and needs to be replaced on time.
3. If the current is less than 3.5 mA, it can be determined that the electronic module of the radar level meter is faulty and needs to be replaced promptly.
