Flow instrumentation supplier factory from China: 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.

The electromagnetic wave emitted during measurement can pass through the vacuum, no transmission medium is required, and the anti-interference ability is strong, and it is not affected by temperature, wind, water vapor, water mist, rain, etc. It can be used for liquid level measurement of almost all liquids, and can be continuously measured on-line unattended. Large measurement range, high precision, mature technology and stable performance.
Level Measurement Considerations: Taking advantage of a specific technology’s ability to reliably address the level measurement in either of these vessels, especially the blowdown flash tank, in a plug-and-play type installation and commissioning format is an easy way to ensure optimal performance. This forgoes calibration, external hardware or inputs. Estimates of up to 49 percent of the energy can be recovered through the use of flash steam routed to heat exchangers or the deaerator to preheat boiler makeup water or support the deaeration process, respectively. In addition, better level control technology at the boiler side eliminates energy losses resulting from unnecessary blowdown to prevent carryover conditions.
Temperature Compensation- Precision in Any Environment Another advancement in guided radar level measurement technology is the incorporation of mechanisms that compensate for temperature variations. Temperature fluctuations in microwave module circuits can lead to inaccuracies in measuring levels. To tackle this challenge, radar level measurement systems have implemented creative solutions. A crucial aspect of these advancements involves allocating a portion of the radar transmission pulse as a reference pulse. This reference pulse serves as a benchmark for comparing measurements enabling temperature calibration. When temperature changes occur the radar sensor can adjust its measurements accordingly ensuring that environmental conditions have no impact on accuracy. This temperature compensation feature is particularly valuable in applications where significant temperature shifts are common. Industries dealing with temperatures or processes prone to variations, such as petrochemical or food manufacturing sectors, rely on precise measurements. Radar sensors equipped with temperature compensation mechanisms rise to the occasion by delivering reliable results despite changing conditions.

The radar level gauge works by electromagnetic waves. Its working principle is to measure the specific liquid level by transmitting electromagnetic waves to the measured target. After the electromagnetic waves are emitted, they are reflected by the medium. For the radar level gauge, its key function is to ensure that it can transmit magnetrol guided wave radar signals smoothly. In our industrial production site, interference often occurs, so which interference sources will affect the measurement of the radar level gauge? let’s see.
Rod antenna: generally used in strong corrosive environments, with weak anti-interference ability and small range; Flare antenna: stronger anti-interference ability, suitable for more complex environments. The larger the bell mouth, the more concentrated the energy, and the larger the measuring range; Parabolic antenna: the focusing effect is stronger than that of the bell mouth, the anti-interference ability is the strongest, and the range is the largest.
So what can be done about these difficulties? Under the condition of strong dust, on the one hand, the radar with high transmitting energy can be selected, on the other hand, the measurement software with continuous measurement algorithm of wave-loss waiting can be selected. When the radar encounters strong dust, it will not misjudge the measurement result even if the radar loses wave for a short time. After entering the state of continuous measurement algorithm, if the reflection wave of real material surface can be recognized within the set waiting time, the correct measurement value of material surface can be obtained. In the past, only a few foreign radars have this function. At present, there are also domestic radars with this function, and the practical application effect is very good.
For the ultrasonic instrument that continuously measures the liquid level, when the temperature of the liquid to be measured changes greatly, the change of the propagation speed of the sound wave should be compensated. The connecting cable between the detector and the converter should take anti-electromagnetic interference measures. The structure of the ultrasonic level sensor should be determined according to the process requirements and on-site working conditions.
