　　Advantages and Applications of Radar Water Level Gauge

　　1. Radar level gauges can measure liquid and solid media such as slurries, 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. The power supply and output signal 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 a reliable resolution of 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, waveguide pipe installation;

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

　　Maintenance of radar level gauge

　　Radar level gauges are mainly composed of electronic components and antennas, with no movable parts. They rarely encounter malfunctions during use. Occasionally, some volatile organic compounds in the storage tank may crystallize on the horn mouth or antenna of the radar level gauge. Regular inspection and cleaning are sufficient, and maintenance is minimal.

　　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.

　　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.
