Overview

A universal radar level gauge is a measuring instrument based on the principle of time travel. The radar wave travels at the speed of light, and the running time can be converted into a level signal through electronic components. The probe emits high-frequency pulses that propagate at the speed of light in space. When the pulses encounter the surface of the material, they are reflected back and received by the receiver inside the instrument, which converts the distance signal into a level signal.

Product Details

radar level gaugeExtremely short microwave pulses with low emission energy are transmitted and received through an antenna system. Radar waves travel at the speed of light. The running time can be converted into level signals through electronic components. A special time extension method can ensure stable and accurate measurements in a very short period of time.

Even in complex working conditions where false echoes exist, the microprocessor technology and debugging software used can accurately analyze the echoes of the material level.

principle

edit

radar level gaugeIt is based on the principle of time-domain reflection (TDR), and electromagnetic pulses propagate along steel cables or probes at the speed of light. When they encounter the surface of the measured medium, some of the pulses are reflected to form echoes and return to the pulse emitting device along the same path. The distance between the emitting device and the surface of the measured medium is proportional to the propagation time of the pulse between them. The liquid level height is calculated based on this principle^[

Advantages and Applications

edit

1. It can measure liquid and solid media such as crude oil, slurry, raw coal, pulverized coal, volatile liquids, etc;

2. It can measure all media with a constant greater than 1.2 in vacuum, with a measurement range of up to 70m;

3. Power supply and output signals are transmitted through a two core cable (loop circuit), using 4-20mA output or digital signal output;

4. Non contact measurement installation is convenient and uses extremely stable materials that are sturdy and durable, with accurate and reliable resolution up to 1mm;

5. Not affected by working conditions such as noise, steam, dust, vacuum, etc;

6. Not affected by changes in medium density and temperature, the process pressure can reach 400 bar, and the medium temperature can reach -200 ℃ to 800 ℃;

7. There are multiple installation methods to choose from: top installation, side installation, bypass pipe installation, and waveguide installation;

8. Debugging can be done in multiple ways: using programming module debugging (equivalent to an analytical processing instrument), SOFT software debugging, and HART handheld programmer debugging, making debugging convenient and fast
