Many manufacturers call it an intelligent radar level gauge; is this the same as what is commonly referred to as a pulse radar level gauge? I’m a bit confused now. If not, please make a distinction – differentiate it from a technical perspective. I would be very grateful. .
It means the same thing; it’s also known as a microwave radar level gauge. Different names are used
;I just started working with this area and feel confused
Pulse radar measures the time difference between the transmitted wave and the echo; for example, it transmits a signal once per second and waits 1.0001 seconds for the echo signal to arrive. Based on this time difference of 0.0001 seconds, the distance can be calculated. This radar technology is simple and has low precision. High-precision radar instruments all use continuously frequency-modulated waves and fast Fourier transforms. The principle is that it changes linearly continuously within a frequency range. Due to the time difference, echoes and continuous waves produce different frequencies. For example, at 0 seconds the transmission frequency is S; after 0.0001 seconds, when the transmission frequency has changed to S1, an echo with frequency S is received. If the rate of frequency change is known, the frequency difference between S and S1 is proportional to the distance measured by the radar. The numerical value of the count of frequency differences is n times larger than that of the count of time differences, which allows for very high precision. The high-precision radar level gauges mentioned today all use horn-shaped or flat antennas to generate radar waves, but there are still differences in their principles.
Like other smart instruments, intelligent radars differ from ordinary transmitters only in that they have communication capabilities and their signal processing is digital; in other words, a CPU is built into the radar detector, and the radar signals are sent directly to this CPU for digital processing. Traditional transmitters achieve signal conversion through a combination of n analog amplifiers and resistor circuits. The advantages of digital signal processing include the ability to adjust the range online, enable communication, and facilitate the transmission of multiple radar parameters. Conversely, there are few remote meters that are traditional analog meters these days. All, almost all radars are intelligent. It’s just that many large manufacturers consider this to be standard, so they don’t make a special effort to promote it.
Understood, conduct a thorough inspection. Thank you: handshake
