Problems with ultrasonic and radar level gauges

Ultrasonic waves: Radar: What technical parameters should be considered during selection and what process requirements must be met?
The question is too general; it’s hard to answer it. You need to take various factors into consideration when choosing a gauge. Electrical interfaces, materials, sealing methods, precision, connection methods, installation methods, output methods; whether there is an on-site display, wiring type, power supply, and so on. For the field application, information such as the type of fluid being measured, pressure, temperature, range, and so on must be provided. For storage tanks, it may also be necessary to specify whether there are features such as mixing systems, waveguide tubes, or heating elements, as well as the dimensions of the waveguide tubes and the sizes of the installation flanges, and so on
Medium, range, tank type, electrical interface, temperature, pressure, explosion protection, signal output, etc. . :)
Be sure to pay attention to the structure inside the container; not all containers are suitable for use with radar/ultrasound. Also, pay attention to the dead zone issue and whether waveguiding is needed. The rest are routine issues: material, pressure rating, explosion protection, electrical interfaces, precision, and other standard requirements.
Ultrasonic waves have weaker interference resistance compared to radar, and it seems that ultrasonic systems don’t have a two-wire system
