On site measurement of electrical contact liquid level

On site measurement of electrical contact liquid levelHigh quality production price quote manufacturer, welcome to consult about liquid level measurement table related issues3. Output signal: 4-20mADC (dual line system); The input formula level gauge is based on the principle that the measured fluid static pressure is proportional to the liquid height. It uses the piezoresistive effect of diffused silicon or ceramic sensitive elements to convert the fluid static pressure into an electrical signal, which is temperature compensated and linearly corrected before being converted into a 4-20mA standard current signal output. The sensor part of the input static pressure level transmitter can be directly placed into the liquid, and the transmitter part can be fixed with flanges or brackets, making installation and use very convenient. 7. Environmental temperature: -40~+60 ℃; Characteristics and functions of magnetic flip column level gauge: It has a wide range of applications, diverse installation forms, and is suitable for measuring the liquid level and interface of any medium. The measured medium is isolated from the indicator structure and has good sealing and leak proof properties. It is suitable for liquid level measurement under high pressure, high temperature, and corrosive conditions, with high reliability. Integrating on-site indication, remote transmission, transmission, and alarm control, it can be freely adjusted and has complete functions. The dual color indicator strip emits light, is continuous, intuitive, and eye-catching, with a large measurement range and the observation direction can be changed freely. Has good vibration resistance and can work in situations with large fluctuations in liquid level. Simple structure, easy installation, and low maintenance cost. Equipped with a precision magnetic steel corrector, it can be adjusted freely on site. The magnetic float level gauge consists of two parts: the on-site indication part and its auxiliary device. Users can also choose the instrument to perform intermediate testing on various towers, tanks, tanks, spherical containers, boilers and other equipment. This liquid level gauge series can achieve high sealing and leak prevention, suitable for high temperature, high pressure, and corrosion-resistant applications. It compensates for the defects of the liquid level gauge glass plate (tube), such as poor clarity of indication and susceptibility to damage. The entire measurement process has no blind spots, clear display, and a large measurement range. Due to measurements indicating that the parts do not come into direct contact with the medium, it has advantages over high temperature, high pressure, toxic, harmful, and highly corrosive media. Therefore, it has a high reliability, safety, reliability and practicability level gauge and quartz tube level gauge function. When installing, attention should be paid to: the installation should be perpendicular to the surface of the object to be measured, avoid using objects measuring foam performance, and avoid the installation distance from the surface of the object being less than the blind area distance (blind area: each product has a standard, and should be installed together with the product. The light beam should be considered to avoid blocking the material from contacting the filling port and the container wall, and the probe direction should be adjusted to detect large solid objects, so as to reduce the measurement error..

1. The installation of the magnetic flip level gauge must be vertical to ensure that the float component can move freely up and down in the main tube. With the help of red and green flakes, the liquid phase will display green, and the gas phase will display red during the measurement process. Liquid gas phase display, float level gauge uses a float as a measuring element, and when the liquid level changes, the float floats up and down accordingly. The heavy hammer (including magnetic steel) in the main riser is driven by a flexibly connected traction cable to move the buoy synchronously in the opposite direction. The magnetic coupling effect between the magnetic steel and the magnetic disc drives the magnetic disc to rotate 180 degrees. When the liquid level rises, the top of the display is the lower limit of the liquid level (i.e. zero position), and the bottom of the display is the upper limit of the liquid level (i.e. full scale). The display uses red to indicate the liquid level, and the bottom is white to indicate that no liquid continues to rise and fall with the increase of the liquid level, while white continuously decreases and falls. Therefore, the display continues to expand the liquid level of the quartz tube level gauge (hereinafter referred to as the color level gauge) in red. It was developed using domestic and foreign technologies. It utilizes the principle of folding and reflecting natural light in liquids, and uses red and green flakes to display the liquid phase as green and the gas phase as red during the measurement process. Due to the high contrast between liquid and gas phases and clear display, it is more conducive to long-distance operations and night patrols. If a light-emitting diode light source is provided, the display screen will be clearer. Widely used for liquid level measurement of various transparent liquid containers and boilers in industries such as petroleum, chemical, power, metallurgy, etc., including oil products and chemical raw materials such as water, gasoline, liquefied gas, liquid ammonia, propane, propylene, aromatic hydrocarbons, acids, etc. Meanwhile, the tri color interface quartz tube level gauge can be selected for interface measurement of two different medium densities. The tri color interface quartz tube level gauge is designed based on the principles of different buoyancy and specific gravity. The small float inside the quartz tube is suspended at the junction of two media. Due to the black color of the float, the color of the upper and lower liquid is different, so the display is obvious. Thus solving the problem of unclear distinction between the interfaces of two mixed media in the petrochemical production process. This is the current quartz tube for direct reading liquid level gauges both domestically and internationally, (1). Remote transmission support instruments should be located near the main pipe of the liquid level gauge and fixed with stainless steel clamps (iron is prohibited); 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. Purpose: Magnetic baffle level gauge can be directly used to observe the liquid level height of various media in containers, and is suitable for liquid level indication in industrial fields such as petroleum and chemical industry. The present invention has a simple structure, intuitive and clear observation, no blockage or leakage, easy installation, and simple maintenance. The upper and lower flange level gauges of the glass plate are connected to the container to form a communication device. Through the glass plate, the actual height of the liquid level in the container can be directly observed. The upper and lower valves are equipped with safety steel balls. When the glass is accidentally damaged, the steel ball automatically seals under the pressure inside the container, preventing the liquid inside the container from overflowing and ensuring the safety of the operator..

Glass level gauge, 1. Widely applicable, with diverse installation forms, suitable for measuring the liquid level and interface of any medium.

g: Local gravity acceleration, installation instructions: When When The ultrasonic wave is at zero liquid level, the top light is on, and the output current is 22mA. In addition, when the liquid level recovers after a period of time, the fault cannot be automatically resolved. After power failure and restart, the fault will return to normal, causing unnecessary trouble and even losses to the user. 3. 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. The self sealing pressure of the steel ball is 0.2 megapascals. There are two installation modes: side installation and top installation. Regardless of the method, the remote transmission equipment can be bundled together. The level gauge can display the liquid level locally and monitor it remotely. The restrained magnet level gauge can be referred to as a remote-controlled launch magnet flap level gauge.

Liquid level measuring gauge

The electronic module of the liquid level measuring meter can output a 20mA signal with overvoltage protection, providing clear, intuitive, and reliable readings. It is used for magnetic level gauge maintenance and static pressure level gauge application. The valve end of the instrument is equipped with a plug screw, which can be used to sample or discharge residual liquid in the instrument during maintenance. Principle: Magnetic flap level gauge (also known as magnetic float level gauge) is developed based on the principle of buoyancy and magnetic coupling effect. When the liquid level in the test container rises or falls, the body tube of the magnetic float level gauge also rises and falls. The permanent magnet steel in the float is transmitted to the magnetic column turn indicator through magnetic coupling, driving the red and white column turn indicator to rotate 180 degrees. When the liquid level rises, the turn signal indicator light changes from white to red. When the liquid level drops, the steering column indicator changes from red to white. The red and white connector of the indicator represents the actual height of the liquid level inside the container, thereby achieving clear indication of the liquid level.
