Application of liquid level measurement

Application of liquid level measurementHigh quality production price quote manufacturer, welcome to consult about liquid level measurement table related issuesQuartz tube level gauge function, 4. The medium should not contain solid impurities or magnetic substances to avoid adhesion to the float. The working principle of ultrasonic level gauge is that the ultrasonic transducer (probe) meets the surface of the measured liquid level (material) and is reflected back. The reflected echo is received by the transducer and converted into an electrical signal. The propagation time of the sound wave is proportional to the distance from the sound wave to the surface of the object. The relationship between the propagation distance S, sound velocity C, and propagation time T of sound waves can be expressed by the following equation: s=c * t/2. The liquid level gauge operates based on the principles of buoyancy and magnetic coupling. When the liquid level in the container to be tested rises and falls, the main pipe of the liquid level gauge also rises and falls. The permanent magnet steel in the float is transmitted to the high-precision electronic sensing element in the field display box through magnetic coupling, and triggers the corresponding digital circuit, causing the LED dual color light-emitting tube to change color. If there is no liquid, it is all red, and if it is full, it is all green. The red and green colors are the actual liquid level in the container, achieving on-site indication of the liquid level, which is clear at a glance; Add limit switches to achieve liquid level alarm and control, and add transmitters to achieve digital signal output for display and control. When the instrument steel ball is installed on the upper and lower valves and the glass plate is accidentally damaged, the steel ball will block the channel under the pressure inside the container, thereby automatically sealing the container and preventing the liquid inside from flowing out. Tube level gauge.

Selection point: Choosing the right radar level gauge can 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 fluid medium being measured? Manufacture the diameter, flow range, lining material, electrode material, and output current of radar instruments. Be able to adapt to the properties of the measured fluid and the requirements of flow measurement. When cleaning, first open the nut level gauge iron pipe, carefully remove the magnetic level gauge, and then clean the debris around the equipment. The input formula level gauge is based on the principle that the measured fluid static pressure is proportional to the liquid height, and is made of an isolated diffusion silicon sensitive element or a ceramic capacitive pressure sensitive sensor. Static pressure is converted into electrical signals, and then temperature compensation and linear correction are performed to convert them into standard electrical signals (usually 4-20mA/1-5VDC). It is also known as "static pressure" level gauge, level transmitter, level sensor, and level sensor. Magnetic flap level gauge produces level gauges that are suitable for various environments and materials according to specific working environments, including hydraulic press level gauges, corrosion-resistant magnetic baffle level gauges, insulated sheath valve level gauges, high-temperature and high-pressure magnetic flap level gauges, top mounted magnetic float level gauges, glass plate level gauges, antifreeze level gauges, glass tube level gauges, colored quartz tube level gauges, and magnetic tube series. Power supply voltage: 24VDC; Low cost, small size, and light weight, it can be used for non-contact liquid level measurement of liquids and bulk solids in industries such as food, chemical, and semiconductor. It can also be used for remote liquid level monitoring and pump control. Mechanical installation and use.

1. The level gauge of the maglev train must be installed vertically to ensure that the float component can move freely up and down in the main pipe. The daily maintenance of the backup area usually includes daily maintenance and weekly maintenance, also known as daily maintenance and weekly maintenance. Features: simple structure, easy installation and maintenance, corrosion resistance, no need for power supply, explosion-proof, 4. The remote transmission support instrument should be tightly connected to the liquid level gauge main pipe and fixed with stainless steel clamps (iron is prohibited); Durability.

Liquid level measuring gauge

When CBM-2100/CBM-2700 input static pressure level gauge is equipped with remote transmission support instrument, the following points should be achieved: due to the certain width of the transmitted ultrasonic pulse, the reflected wave in the small area near the transducer overlaps with the transmitted wave, making it difficult to identify and measure the distance value. This area is called the measurement blind spot. The size of the blind spot and the ultrasonic probe part emit ultrasonic waves, which are then reflected by the liquid surface and received again by the probe part. The magnetic tilt column level gauge is developed based on the principle of buoyancy and magnetic coupling effect. When the liquid level in the test container rises and falls, the magnetic float in the main tube of the level gauge also rises and falls. The permanent magnet steel in the float is transmitted to the magnetic flip column indicator through magnetic coupling, driving the red and white flip column to rotate 180 degrees. When the liquid level rises, the flip column changes from white to red. When the liquid level drops, the flipping column changes from red to white. The red and white boundaries of the indicator represent the actual height of the liquid level in the container, achieving clear indication of the liquid level. The magnetic flip column level gauge is a dual color magnetic flip column level indicator driven by a magnetic float, which can be used for liquid level detection in various towers, tanks, jars, spherical containers, boilers, and other equipment. It can achieve high sealing, leak prevention, and liquid level measurement under high pressure, high temperature, and corrosive conditions. It is safe and reliable, overcoming the disadvantages of unclear indication and easy breakage of glass plates (pipes). The liquid level gauge is not affected by drastic changes in high and low temperatures, does not require multiple sets of liquid level gauges, and has no blind spots in the entire measurement process. The display is eye-catching, the reading is intuitive, and the measurement range is large. Especially the on-site indication part does not come into direct contact with liquid media, which is more advantageous than high temperature, high pressure, high viscosity, toxic and harmful, and highly corrosive media. It has higher reliability, safety, reliability and applicability than traditional glass plate (tube) liquid level gauge is suitable for continuous measurement and control of liquid level, oil level, oil-water interface and foam interface in metallurgy, petroleum, chemical industry, shipping, environmental protection, power, paper making, pharmacy, printing and dyeing, food, municipal and other industries. The structure is simple and easy to maintain, with external thread G3/4 "(or M27 × 1.5) for wire installation.

Liquid level measuring gauge

The other characteristics of the liquid level measuring gauge are the same as those of the ultra-high temperature of -50 ℃. In order to ensure the self sealing effect, the medium pressure in the container should be greater than 0.2 megapascals, with clear, intuitive, and reliable readings. The sealed electronic module and dual filter pressure compensation system can resist the influence of on-site climate change. The working temperature is -20 ℃+200 ℃. If the dielectric constant of the medium is low and the bottom of the tank is visible when it is at a low liquid level, it is recommended to set the zero point at a low C height to ensure measurement accuracy. Do not use brushes or metal tools with high hardness inside the cleaned liquid level gauge to avoid damaging sensitive core wires and pressure interface threads..

Application of liquid level measurement4. When the level gauge is put into operation during magnetic flipping, the valve of the lower guide pipe should be opened to allow the liquid medium to smoothly enter the main pipeline, in order to avoid steering column failure and steering confusion caused by the rapid rise of the liquid medium due to the floating ball component. If this phenomenon occurs, the magnetic steel can be used for recalibration after the liquid level stabilizes. The ultrasonic level gauge consists of three parts: *, processing unit, and output unit. The pipeline is installed with external thread G3/4 "(or M27 × 1.5), and the display is isolated from the measured medium *, ensuring safety and reliability. The end faces of the two flanges on the container and the glass tube level gauge connected to the two flanges should be ensured to be on the same vertical plane, otherwise the valve will bend after installing the level gauge, causing the glass tube to rupture. 1. Accuracy function checks the accuracy level, and selects the instrument accuracy level based on measurement requirements and application scenarios to achieve economic benefits. For example, when used for trade settlement, product transfer, and energy measurement, higher accuracy should be chosen, such as 1.0, 0.5, or higher. For process control scenarios, different accuracy levels should be selected according to control requirements; In some cases, if only the process flow is detected without precise control and measurement, a slightly lower accuracy process can be chosen, such as 1.5, 2.5, or even 4.0, and then the level gauge can be selected by choosing a low-cost plug-in radar. The working principle of ultrasonic level gauge is that the ultrasonic transducer (probe) meets the surface of the measured liquid level (material) and is reflected back. The reflected echo is received by the transducer and converted into an electrical signal. The propagation time of the sound wave is proportional to the distance from the sound wave to the surface of the object. The relationship between the propagation distance S, sound velocity C, and propagation time T of sound waves can be expressed by the following equation: s=c * t/2.
