Flow meter provider 2024: The second case is that, in order to ensure the fluidity of crude oil, offshore oil platforms usually use hot medium oil heating pipes to heat the crude oil to ensure that it is stored within a certain temperature range. As the crude oil in the lower tank contains a small amount of water, some of the bottom water will precipitate out of the bilge water after standing, and the water vapor will evaporate during the continuous heating process. The water vapor condenses on the antenna at the top of the tank to form water droplets, causing a strong false signal at the top. Therefore, false signals are suppressed within 0~0.25m and the suppression line is set to 120dB to avoid false signals caused by water vapor condensation and level jumps at the top. In response to this situation, after on-site analysis and research tests decided to do a good job of pre-dewatering treatment, the water content of the crude oil in the lower tank is controlled at less than 0.5%, the heating temperature of the crude oil tank is controlled so that the crude oil in the tank is lower than 65 ℃, and the instrumentation is covered with thermal insulation materials on the outside, etc. Through the above measures, the phenomenon of level jumping caused by the formation of condensation at the antenna of the radar liquid level meter is eliminated.

With the continuous advancement of science and technology, radar water level meters have been used more and more. It has the advantages of low cost, high stability, flexibility, high reliability, low power consumption, convenient parameter setting, safe and simple maintenance, etc., and has important promotion value. Today, the editor will take you to a simple understanding of radar water level meter. Radar water level meter is a kind of measurement equipment introduced from abroad in recent years. The water level meter has mature technology, high measurement accuracy, easy installation, and is not restricted by environment and geography, so it has been widely used.
For more accurate measurement in deaerators, magnetrol guided wave radar (GWR) is a preferred option. Since its performance and accuracy are not contingent on the specific gravity and/or inference, it can provide reliable measurements in all situations, including the difficult and turbulent process conditions of deaerators and feedwater heaters. In addition, GWR does not require external inputs or calibration to achieve specified performance. This effectively eliminates the introduction of errors during the calibration process or from external sources, i.e., pressure and temperature. With this high level of accuracy, operators can trust that their deaerators will be well controlled.
Radar level measurement represents a shift in the field of instrumentation. This state-of-the-art technology utilizes radar waves to determine levels of liquids or solids, in vessels. Unlike methods that require contact radar operates non invasively by emitting microwaves and carefully analyzing the reflected signals. The key radar level measurement principle here is time of flight measurement- accurately measuring the time it takes for a radar pulse to travel from a transmitter, bounce off the surface of the material and return to a receiver. This temporal data is then converted into an accurate level reading.

The interference comes not only from the outside, but also from the inside of the radar level gauge, such as interference caused by wires, inductance and capacitance between the power transformer and electronic components. In addition, the internal components can also generate noise interference. Today, most radar level gauges have also begun to be improved, using high-frequency microwave technology, which greatly improves the performance of the level gauge and reduces interference.
Power supply and output signal, the power supply has 220 V A C, 24 VDC, and the two-wire or four-wire system can be selected according to the needs. Output signal 4 ~ 20 mA DC or digital signal, select the appropriate model according to the needs. The above are all factors that need to be considered when selecting a radar level transmitter. The essence of the details is a serious attitude and a scientific spirit. I hope that every user can choose a suitable radar level meter.
In the process of cement production, material level detection and material level alarm control play an important role from mining and crushing to storage and packing of finished cement. But because of the complex working conditions of cement plant, radar level meter has no small difficulty in measuring. Today, I would like to talk with you about specific difficulties and solutions. First cement plant material for measurement in the dust under the condition of particularly large, especially some pneumatic feed bin, involves the kinds of materials, material particle size is differ, dielectric constant is different also, such as broken limestone, raw meal, clinker, fly ash, coal, cement, the level of the bunker, it is very difficult to accurately measure Especially fly ash bin with low dielectric constant.
The installation of the liquid level gauge should be away from the inlet, outlet, eddy current or protrusions on the inner wall to avoid the interference of electromagnetic waves and affect the measurement. When installing the guided wave radar, make sure that the diameter of the short pipe at the flange connection is greater than the height of the short pipe, otherwise the cable will contact the short pipe wall due to shaking, and the liquid level cannot be measured accurately. How to choose a model, in the final analysis, you still need to understand your own working conditions and the characteristics of different instruments, and judge whether the two match, so that you can get twice the result with half the effort.Want to know about ultrasonic flow meter advantages and disadvantages, click here.
There is AC interference and the voltage is high. For example, for the radar level meter used in the production line, the power supply requirement is 24VDC (typical value), but in the on-site measurement, it is found that the power supply is displayed as 27.2V, which is significantly higher than 24VDC, resulting in a large measurement result and even a radar level meter. crash phenomenon. The installation position of the radar level meter is incorrect, which leads to deviations in the measurement. For example, the accumulation of aggregates in the transfer bin is a “mountain”-shaped cone, but only one radar level meter is installed near the discharge port of the return belt. , the installation position is too close to the discharge opening of the return belt, and at the same time, it is too far from the discharge opening of the feeding belt on both sides. Just below the radar level meter is the drop point of the return belt. If the distance is too close, the aggregate in the falling process will interfere with the radar level meter and form false reflections.
