Level measurement instrument manufacturer by kaidi86.com

Level measuring devices manufacturer from China: The emergence of IIoT-enabled radar sensors represents a shift in how industries operate. These sensors are no longer data providers- they now function as nodes within interconnected industrial ecosystems. Here are some key aspects that highlight their enhanced capabilities: Real time Data Monitoring- IIoT-enabled radar sensors continuously collect and transmit real time data regarding material levels. This data is not limited to displays and can be accessed securely from virtually anywhere through network connections. See additional info on level measuring instruments.

In the measurement circuit of the radar level gauge, when there is additional DC current and voltage, it is DC interference. In severe cases, the measuring instrument will not work properly. The sources of DC interference are as follows: AC interference can be divided into line-to-line interference and ground interference. Inter-line interference refers to the AC voltage between the output ends of the radar level gauge (compensation line) under external influence. This interference is also known as lateral, common mode or common mode interference. Generally speaking, the line-to-line interference voltage can reach several millivolts or even tens of millivolts.

Working principle: Tube in the liquid level meter has a magnetic float, float design, according to the proportion of medium float magnet steel and container liquid level at the same level, wholesale liquid level gauge in a semiconductor magnetel liquid level gauge sensor LED display scale, and orderly arranged from top to bottom, and LED module corresponding to the magnetic field magnetic sensor, the magnetic semiconductor, triggering the corresponding digital circuit, liquid level above the red LED display, The LED below the liquid level gauge is displayed in green, the red in gas phase, and the green in liquid phase. The red-green junction is the actual liquid level in the container.

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 are the installation technical requirements for radar water level meters? The installation of the radar water level meter must be vertical to the object to be measured; there should be no obstructions between the measured object and the radar water level meter, otherwise it will affect the reflection of radar waves, that is, affect the measurement accuracy; the center of the radar water level meter is far from the shore of the water body. The distance must be greater than the radius of the transmitting beam, otherwise the measurement accuracy will also be affected; the installation cantilever bracket of the radar water level meter must be firm, and cannot be shaken up and down; in order to protect the radar water level meter, the water level meter can be installed on the cantilever bracket. Iron box, put the radar water level meter probe.

Any appreciable gain in boiler feedwater achieved through the process reduces the amount of energy (fuel) required at the boiler— in fact, every 10.8°F (6°C) rise in boiler feedwater amounts to a one percent savings in fuel cost. Inadequate level controls can inhibit the deaeration process (level too high) or reduce/shutdown feedwater flow to the boiler (level too low). The former affects hardware longevity and efficiency, while the latter risks production losses and possible damage to pumps. Read additional information on https://www.kaidi86.com/.

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.

Under many operating conditions, ultrasonic level meter and radar level meter are commonly used. Some users are very entangled in the choice of these two level meter and do not know how to choose. Today, let’s talk about the principles and selection principles of these two types of level meter . Principle and selection principle of ultrasonic level meter. Working principle: The ultrasonic pulse probe emits a beam of ultrasonic pulses to the measured medium, and the sound wave is reflected by the liquid surface. The distance between the liquid levels is measured by measuring the time difference between the emission and reflection of the sound waves. Since the ultrasonic level gauge is not a liquid, it can be used to measure corrosive, non-volatile and non-foaming places.

Radar level meter adopts non-contact measurement, and has the advantages of high measurement accuracy, not affected by process conditions, easy to install and easy to maintain, so it is widely used in offshore oil platforms in recent years. Today, we would like to take you through several actual cases in offshore oil platform to understand the reasons and solutions of the radar level meter’s measurement value jumping. The first case was an oil field where the radar level meter in the left crude tank jumped to full scale several times during production. A sealed metal cover was used to cover the main body of the sensor, and during the test, it was found by connecting the radar level transmitter that the closed metal cover would result in more false signals throughout the measurement range, and the overall noise line would rise.
