Description :

　　With the improvement of industrial automation level, radar level gauges have been widely used in fields such as petroleum, metallurgy, and chemical engineering In the industrial production process, even small measurement errors of level gauges can cause huge economic losses, and improving the measurement accuracy of level gauges has become an urgent need.

　　Measurable medium

　　When measuring medium flow rate, instrument range, and caliber for general medium measurement, the full-scale flow rate of the radar level gauge can be selected within the range of 0.5-12m/s for measuring medium flow rate, which is relatively wide. The selection of instrument specifications (caliber) may not necessarily be the same as the process pipeline, and should be determined based on whether the measured flow range is within the flow rate range. That is, when the pipeline flow rate is too low to meet the requirements of the flow instrument or the measurement accuracy cannot be guaranteed at this flow rate, the instrument port diameter needs to be reduced to increase the flow rate inside the pipeline and obtain satisfactory measurement results.

　　Measurement principle of radar level gauge

　　Radar level gauge is a radar level gauge based on the principle of time domain reflection (TDR). The electromagnetic pulse of the radar level gauge propagates along the steel cable or probe at the speed of light. When it encounters the surface of the measured medium, some of the pulses of the radar level gauge 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, and the liquid level height is calculated.

　　Precautions for radar level gauge

　　1. The measurement range starts from the point where the beam touches the bottom of the tank, but in special cases, if the tank bottom is concave or conical, measurement cannot be carried out when the level is below this point.

　　If the medium has a low dielectric constant and the bottom of the tank is visible when it is at a low liquid level, it is recommended to set the zero point at a low height of C to ensure measurement accuracy.

　　In theory, it is possible to measure the position of the antenna, but considering the effects of corrosion and adhesion, the final value of the measurement range should be at least 100mm away from the antenna.

　　4. For overflow protection, a safe distance can be defined to be added to the blind spot.

　　5. The small measurement range is related to the antenna.
