1. Precision function inspection
Accuracy grade and function: Select the accuracy level of the instrument according to the measurement requirements and use occasions, so as to be economical and cost-effective. For example, when it is used for trade settlement, product handover and energy metering, a higher accuracy level should be selected, such as 1.0, 0.5, or higher; For the occasion of process control, different accuracy levels are selected according to the control requirements; For those occasions where the process flow is only detected and does not need to be controlled and measured, a slightly lower accuracy level can be selected, such as 1.5, 2.5, or even 4.0, at which point a low-cost plug-in radar level gauge can be selected.
2. Measurable medium
When measuring the flow rate of the medium, the range of the instrument and the diameter of the general medium, the full flow rate of the radar level gauge can be selected in the range of 0.5-12m/s of the flow rate of the measuring medium, and the range is relatively wide. The specification (caliber) of the instrument is not necessarily the same as that of the process pipeline, and it should be determined according to whether the measured flow range is within the flow rate range, that is, when the flow rate of the pipeline is low and cannot meet the requirements of the flow meter or the measurement accuracy cannot be guaranteed under this flow rate, the instrument diameter needs to be reduced, so as to increase the flow rate in the pipe and obtain satisfactory measurement results.
