SOLIDAT--how To See The Echo Curve Of Guided Wave Radar Level Transmitter

SOLIDAT guided wave radar level transmitter is an industrial instrument commonly used to measure liquid or solid materials. By analyzing the echo curve, the liquid level information can be obtained accurately. This article will introduce how to correctly interpret the echo curve diagram of the SOLIDAT guided wave radar level meter manufacturer.

1. Understand the basic structure of the echo curve

The echo curve graph of SOLIDAT coaxial probe guided wave radar usually consists of two main parts: the distance axis and the reflection intensity axis. The distance axis represents the time of propagation of the radar signal, i.e. the distance between the material and the level gauge. The reflection strength axis represents the strength of the echo signal, which is used to judge the presence and characteristics of the material.

2. Observe the shape of the echo curve

--Smooth straight line: When there is no obstacle between the liquid level gauge and the material, the echo curve usually appears as a flat straight line. This means that the radar signal emitted by the guided wave radar level gauge directly reaches the surface of the material and returns without being interfered by any object.

--Curve with fluctuations: When there are obstacles such as air bubbles, foam or particles between the radar guided wave level gauge and the material, the echo curve may show a fluctuating shape. This is because obstacles scatter part of the radar signal, causing the strength of the echo signal to vary.

--Discontinuous curve: When there is a large inclination or unevenness on the surface of the material, the echo curve may appear discontinuous. This is because reflections of the radar signal between different surfaces can cause drastic changes in the strength of the echoed signal.

3. Analyze the characteristics of the echo curve

--Echo intensity: The peak value of the echo curve indicates the intensity of the echo signal, which can be used to judge whether the material exists or not. Higher peaks usually indicate the presence of material, lower peaks may indicate voids or gas.

--Echo time: The peak position of the echo curve corresponds to the distance between the material and the liquid level gauge. By measuring the echo time, an accurate value for the liquid level can be calculated.

4. Matters needing attention

Ensure the normal operation of the coaxial guided wave radar: Before observing the echo curve, make sure that the liquid level gauge is in normal working condition, such as stable power supply, clean sensor, etc.

Adjustment for different materials: Different materials have different dielectric constants and reflection properties, which may affect the echo curve. Therefore, when using the SOLIDAT guided wave radar level transmitter, it is necessary to adjust the corresponding parameters according to the nature of the material.

By observing and analyzing the echo curves of SOLIDAT guided wave radar level meter manufacturers, we can accurately obtain liquid level information, thereby realizing the monitoring and control of industrial processes. In practical applications, it is necessary to make adjustments and judgments according to the specific situation to ensure the accuracy and reliability of the measurement results.
