Open liquid level measurementHigh quality production price quote manufacturer, welcome to consult about liquid level measurement table related issuesThis instrument can be used in conjunction with a resistance inductance converter to directly output resistance value signals or output current value (4-20mA) signals. At the same time, in conjunction with other converters to output voltage signals and their switch signals (the converters are distributed by the company according to customer requirements), remote transmission and control of electrical signals can be achieved. The self sealing pressure of the steel ball is 0.2 megapascals, with high contrast and clear display, which is more conducive to remote operation and night patrols. Self sealing pressure of steel ball: 0.2mpa, characteristics, 3. When equipped with remote transmission support instruments, the following operations should be performed:.

Ultrasonic level gauges can adopt dual line, three line, or four line technology. The dual line system is: power and signal output are shared; The three wire system is as follows: the power circuit and signal output circuit are independent. When using a DC24V power supply, a three core cable can be used, with the negative power supply end and negative signal output end sharing the same core wire. Four wire system: When using an AC 220V power supply, or when using a DC24V power supply and requiring isolation between the power circuit and the signal output circuit, a four core cable DC or AC power supply, 4-20mA, high and low switch output, and an attractive level gauge should be installed on the extension tube outside the tank. The liquid level inside the tank can be clearly known through a flip indicator. A magnetic switch can also be installed outside the bypass pipe to output electrical contact signals, or the liquid level transmitter of the device can be used for remote liquid level signal transmission and control. An attractive level gauge is a reliable safety tool. The magnetic coupling principle of the level gauge works based on the buoyancy principle. When the liquid level in the measured container rises and falls, the float in the main pipe of the magnetic level gauge also rises and falls. The magnetic steel in the float is transmitted to the on-site indicator through magnetic coupling, driving the red and white steering column to rotate 180 degrees, causing the liquid level to rise and the chromatographic column to change from white to red. When the liquid level drops, the column turns white, and the red and white boundary of the indicator is the actual height of the medium liquid level in the container, thus achieving liquid level indication. , II. Structural principle: MY is an analog liquid level transmitter composed of a liquid level sensor and a signal converter. The liquid level sensor consists of multiple spring pad switches and resistors installed inside a φ 20 stainless steel protective tube, and the protective tube is fastened outside the measuring tube (main tube); The signal converter consists of electronic modules and is installed in an explosion-proof junction box at the top or bottom of the sensor. 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 high reliability, safety, reliability, and practicality as a liquid level gauge, with working pressures of 1.6, 2.5, 4.0, 6.4, and 10.0 MPa, good stability, and an all zero stability of up to 0.1% FS/year within the compensation temperature range of 0-70 ℃. The temperature drift is less than 0.1% femtosecond, and within the entire allowable working temperature range, it is less than 0.3% femtosecond. The glass tube level gauge is a direct reading level measuring instrument suitable for on-site detection of liquid levels in common liquid storage equipment in industrial production. It has a simple structure and accurate measurement, making it a traditional on-site liquid level measurement tool. Usually used for direct detection.

The structure is simple, easy to install and maintain, corrosion-resistant, no need for power supply, explosion-proof. When measuring the flow rate of the medium, commonly used measuring instruments and the range and caliber of the medium, as well as the full flow level gauge of the radar, can be selected within the range of 0.5-12m/s, which is relatively wide. The different specifications (diameters) of the selected instruments are the same as those of the process pipeline, and should be determined based on whether the measured flow range is within the flow range. That is, when the flow rate of the pipeline is too low to meet the requirements of the flowmeter or the measurement accuracy cannot be guaranteed at this flow rate, the diameter of the instrument needs to be reduced to improve the flow rate in the pipeline and obtain satisfactory measurement results. The liquid level displayed on the screen is red, which is intuitive and eye-catching. The precision function checks the accuracy level, and the instrument accuracy level is selected according to the 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. A high-precision and stable ceramic capacitor and imported diffusion silicon measuring device with a measurement range (installation center polygon: 300500800110014001700... mm). The plate level gauge is manufactured according to the original Ministry of Chemical Industry HG5-1364~1370-80 standards and is suitable for directly indicating the liquid level of various media in towers, tanks, cans, boxes, and other containers. The safety steel ball is installed on the upper and lower valves of the instrument. When the glass is accidentally damaged, the steel ball will automatically close the liquid flow channel under the pressure inside the container, preventing the liquid level from flowing out..

Liquid level measuring gauge

Function: In the field of use, the input static pressure level gauge for coalbed methane 2100 coalbed methane 2700 input static pressure level gauge (static pressure level gauge/level transmitter/level sensor/water level sensor) is a pressure sensor used to measure liquid level. The magnetic inversion level gauge is developed based on the principle of buoyancy and magnetic coupling effect. When the liquid level in the measured container rises or falls, the body tube of the magnetic float level gauge in the container 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 columns to rotate 180 degrees. When the liquid level rises, the magnetic flip level gauge column changes from white to red. When the liquid level drops, the magnetic flip level gauge column changes from red to white. The red and white intersection of the indicator represents the actual height of the liquid level in the container. Realize clear liquid level indication, with clear, intuitive, and reliable readings. Due to its enclosed structure and magnetic coupling isolator, it is particularly suitable for detecting the liquid level of flammable, explosive, and corrosive toxic liquids. This makes the existing liquid level detection methods in complex environments simple, reliable, and safe. The liquid level gauge has the direct reading characteristic of local display, which does not require multiple sets of liquid level gauges for full range measurement. This device has the advantages of fewer openings, clear display, prominent markings, and intuitive readings. When the magnetic level gauge is directly equipped with a display instrument, the intermediate transmission of system signal detection can be omitted to improve its transmission accuracy. Ultrasonic level gauge is a digital level gauge controlled by a microprocessor. During measurement, the sensor emits pulsed ultrasonic waves. After the sound wave is reflected by the surface of the object and converted into an electrical signal, it is received by the same sensor. The distance between the sensor and the measured object is calculated by the time between the transmission and reception of the sound wave. Due to non-contact measurement, the measured medium is almost unrestricted and can be widely used for height measurement of various liquids and solid materials. When the ultrasonic level gauge works on the principle of [/Hz/], the transducer (probe) emits high-frequency pulse sound waves. When the surface (water surface) of the measured object is reflected, the reflected echo is received by the same transducer (probe) and converted into an electrical signal. The time between the transmission and reception of the pulse (the movement time of the sound wave) is proportional to the distance from the sensor to the surface of the object. The relationship between the propagation distance S of the sound wave, the speed of sound C, and the propagation time T can be expressed by the formula: S=C × T/2 [/hour/]. When using the level gauge to install an ultrasonic blind spot, it is necessary to consider that the level gauge must be installed when the liquid level enters the ultrasonic blind zone. When there is a blind spot, the ultrasonic transmitter cannot measure the liquid level, so when determining the measurement range, the ultrasonic level gauge must leave 50cm When installing the transmitter probe, the margin must be about 50cm higher than the maximum liquid level. This way, accurate liquid level monitoring and safe ultrasonic waves can ensure the level gauge.

The plate level gauge is manufactured according to the HG5-1364~1370-80 standards of the former Ministry of Chemical Industry, and is suitable for directly indicating the liquid level of media in various containers such as towers, tanks, cans, and boxes. The safety steel ball is installed on the upper and lower valves of the instrument. When the glass is accidentally damaged, the steel ball will automatically close the liquid flow channel under the pressure inside the container, preventing the liquid level from flowing out. The magnetic flip level gauge does not allow the magnetizer to be close to the main body, otherwise it will directly affect the working level gauge of worker F. The magnetic flip plate level indicator is installed on or outside the storage tank to indicate and control the sealing form in the storage tank. Drainage valves can be installed as needed. The connecting flange can accept customized liquid level heights for control instruments. The index includes magnetic color cards. When the float in the magnetic tube rises with the liquid level, the color code flips to display the liquid level height. You can also install technical switches or remote transmitters on the magnetic tube to output switch signals or analog signals.

The pipe body is made of seamless steel pipe, and the connecting pipe is welded through drawing holes, with no scratches inside. The installation mode can be selected between side installation and top installation, and the lower end of the main body is sealed. The working principle of the magnetic tilt column level gauge is that when measuring liquid with a magnetic tilt column, the level gauge should be installed on the top or bypass pipe side of the magnetic tilt column main body. There are flip column level indicators, level switches, and level transmitters. The magnetic unit is set inside the float or connected to the float through a top rod; When the float and magnetic unit change with the liquid level, the magnetic color block (magnetic flip plate) flips; The magnetic liquid level switch acts on the corresponding liquid level point; At the same time, the liquid level sensor outputs a standard variable resistance signal under the action of the floating ball magnetic force, and then converts the resistance signal into a 4-20mA current signal output through a transmitter. The characteristics and functions of the magnetic flip column liquid level gauge are: wide applicability, diverse installation forms, suitable for measuring the liquid level and interface of any medium, isolated from the indicator structure, with good sealing and leak proof performance, suitable for liquid level measurement under high pressure, high temperature and corrosion conditions, and high reliability.
