　　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.

　　Radar level gauge belongs to the general radar level gauge, which is a measuring instrument based on the time travel principle. The radar wave runs 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.

　　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.

　　Two key factors for selecting radar level gauges correctly

　　The correct stacking type of radar level gauge is necessary to ensure better use of the radar level gauge. What type of radar level gauge should be selected based on the physical and chemical properties of the measured fluid medium? Make the diameter, flow range, lining material, electrode material, and output current of the radar level gauge suitable for the properties of the target fluid and the requirements of flow measurement.

　　1. Precision functional inspection

　　The accuracy level and function of the instrument are iteratively selected based on measurement requirements and usage scenarios to achieve cost-effectiveness. For example, in situations such as trade settlement, product handover, and energy measurement, a higher accuracy level should be selected, such as 1.0, 0.5, or higher. In situations such as process control, different accuracy levels should be selected according to control requirements. For some sites that only check process flow and do not require control and measurement, a slightly lower accuracy level, such as 1.5 or 2, can be selected At level 5 or even 4.0, low-cost plug-in radar level gauges can be used repeatedly.

　　2. 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. It should be determined based on the flow rate range of S 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 should be reduced to increase the flow rate inside the pipeline, and satisfactory results should be obtained.
