Many jobs now require the use of professional radar level meters, so we need to have enough understanding of professional radar level meters, which can effectively improve work efficiency, and the price of professional radar level meters is also an issue that everyone cares about. How much is a professional radar level gauge? What is the measurement methodRadar level gaugeThe radar level gauge is a general-purpose radar level gauge. It is a measuring instrument based on the principle of time travel. The radar wave runs at the speed of light, and the running time can be converted into a level signal by electronic components. The detector emits high-frequency pulses that travel at the speed of light in space. When the pulse is in contact with the surface of the material, it is reflected and received by the receiver in the instrument, and the distance signal is converted into a material level signalHow many professional radar level gaugesMeasurement methodsBased on the principle of time domain reflection & 40; TDR and #41; part of the pulse of the radar level gauge is reflected to form an echo, and returns along the same path. However, considering the effects of corrosion and adhesion, the final value of the measurement range should be at least 100 mm from the antenna tip. For overflow protection, the safety distance of the radar level gauge can be defined and added to the blind zone. The minimum measurement range is related to the antenna. At different concentrations, the foam can absorb and reflect microwaves, but it can be measured under certain conditions. Return pulse transmitterMeasuring principleThe radar level gauge is based on the principle of time domain reflection 40; TDR and #41; 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, part of the pulse of the radar level gauge is reflected to form an echo, and returns to the pulse transmitter along the same path. The distance between the transmitter and the surface of the measured medium is proportional to the propagation time of the pulse between themWhat is the professional radar level gaugeWhat is the professional radar level gaugeAs a liquid level gauge, the more functions a radar level gauge has, the more expensive it is. Different models have different prices, such as guided wave radar level gauges, rod radar level gauges, rod radar level gauges, cable guided wave radar level gauges, etc. The final price depends on the model, and the functions are based on comprehensive accounting. The price shall prevail, the professional radar level gauge is generally around 5,000 yuanHow much is a professional radar level gauge? According to Huikeda Instruments, there are many models of professional radar level meters on the market, and the price of each model is different. You can choose how they deal with the interference of radar level gauges according to their functions and prices? What is the troubleshooting methodRadar level gauges are used in many places, so the frequency of radar level gauges is very high and it is prone to failure. So how to deal with the interference of the radar level gauge? How to solve the malfunction of radar level gaugeRadar level gaugeThe radar level gauge is a general-purpose radar level gauge. It is a measuring instrument based on the principle of time travel. The radar wave runs at the speed of light, and the running time can be converted into a level signal by electronic components. The detector emits high-frequency pulses that travel at the speed of light in space. When the pulse hits the surface of the material, it is reflected back and received by the receiver in the instrument, and the distance signal is converted into a level signalHow to deal with the interference of radar level gauge
How to deal with loss of wave or interferenceThe malfunction of the radar level gauge is the appearance of the instrument; wave loss; error or collapse. When measuring low-dielectric constant liquids, wave loss often occurs due to the weak reflection ability of the liquid. However, the alumina industry does not have the problem of weak reflection ability. Therefore, the wave loss is caused by eddy currents, turbulent liquid surface, and thick and thick foam, which cause the radar waves to diffuse or be absorbed, resulting in weak echoes or even no echoes. In this case, the best application parameters should be determined according to the process characteristics of the vessel. If the effect of the above measures is not obvious, the installation position or a larger antenna should be replaced to enhance the echo strength. The use of still-pipe or by-pass pipe is an effective method to solve the frequent wave loss phenomenon, but the installation workload is large and it is not suitable for the mud that is easy to scab.How to deal with the interference of radar level gaugeHow to solve the malfunction of radar level gauge1. Check whether the power supply is normal: If the radar level gauge changes very slowly after the liquid level rises to a certain value at the production site, you should immediately check whether the power supply of the radar level gauge is normal. The relevant personnel should also check the radar fluid during routine maintenance. The power status of the potentiometer and whether there is a normal output after power-on. If the liquid level changes slowly or does not change at all, check whether the fuse of the device is blown out at the first time. If there is no current output, it can be judged that there is a problem with the instrument, and it should be replaced or repaired according to the situation. In addition, management should be strengthened during the installation and commissioning of the instrument to prevent inaccurate setting of instrument parameters from affecting production. Relevant personnel also need to strengthen daily maintenance work, regular power outages for maintenance, to ensure the normal operation of the radar level gauge2. Check whether the communication equipment is normal: Once the communication equipment is abnormal, by installing the radar debugging software, you can read the configuration data of the radar and monitor the status of the radar sensor. It is mainly to check whether the radar sensor can accurately determine the difference between the reflected echo and the false echo, and whether the intensity of the reflected wave reaches the predetermined standard. If there is no problem with the above test, you need to check other electronic components. If it is judged that the communication unit of the radar level gauge is damaged, the parts need to be replaced according to the situation to ensure the normal communication of the radar level gauge. In daily maintenance work, relevant staff should also strengthen the inspection of the communication status of the radar level gauge. The radar debugging software can be used to connect to the signal line, and the regulator can be used to maintain the communication equipment of the radar level gauge
