How is the ultrasonic flowmeter wired?

Just wire it according to the manual! The two wires are the wiring of the two ultrasonic sensing heads, and according to the circumference of the pipe diameter, the installation distance of the two ultrasonic sensing heads.

Ultrasound is a type of mechanical wave with an extremely short wavelength.

In air, wavelengths are generally shorter than 2 cm (cm). It must rely on a medium for propagation and cannot exist in a vacuum, such as space. It travels farther in water than in air, but because of its short wavelength, it is very easy to lose in air and scatter, which is inferior to audible sound and infrasound waves.

It can be transmitted far, but the anisotropy is easier to obtain at short wavelengths.

It can be used for cleaning, stone crushing, sterilization and disinfection, etc. There are many applications in medicine and industry.

The word "super" in ultrasound comes from the fact that the lower bound of its frequency band exceeds human hearing, but if it is analyzed by the wavelength angle, the wavelength of ultrasound is actually shorter. Scientists.

The distance between two adjacent crests or troughs of a wave is called a wavelength, and the wavelength of mechanical waves that our human ears can hear is 2 cm 20 m (2 cm 20 m).

Therefore, we call mechanical waves with a wavelength shorter than 2 cm "ultrasound". However, in practical applications, mechanical waves with a wavelength below (above 10,000 Hz) can be regarded as ultrasonic research. Ultrasound, which is commonly used for medical diagnosis, has a wavelength of 10 m to 350 m.

Ultrasound is a mechanical wave that has to rely on a medium for propagation and cannot exist in a vacuum like space, so we can't use ultrasound in a vacuum, but we can still use and electromagnetic waves.

Related equipment (including radio waves, microwaves, infrared, visible light, ultraviolet rays, X-rays, gamma rays.

etc.), making use of electromagnetic wave technology.

In the air, ultrasonic refers to a wavelength of less than 2 centimeters of mechanical waves (a centimeter, 2cm wavelength corresponds to 17000Hz, wavelength corresponds to 20000Hz, in fact, there is no fixed standard, just a convenient memory value), its wavelength is very short, lower than the general lower limit of human ear hearing (2cm), people call this inaudible mechanical wave ultrasonic, infrasound wavelength is generally longer than 20 meters (one says 17 meters, 20m wavelength corresponds to 17Hz, The wavelength of 17m corresponds to 20Hz), which is higher than the upper limit of the wavelength of hearing.

In practical applications, ultrasound waves often coincide with the range of short-wave audible sound waves, and mechanical waves with shorter wavelengths can be regarded as ultrasound research.

An ultrasonic flowmeter is a non-contact flow meter that measures the flow rate and flow rate of a fluid through the propagation velocity and reflection of ultrasonic waves. The wiring methods of ultrasonic flowmeters are as follows:

1.Two-wire wiring method: the positive and negative poles of the ultrasonic flowmeter are connected to the positive and negative poles of the power supply respectively, this wiring method is simple, but for the case of long-distance transmission of signals, the signal will be interfered with, affecting the measurement accuracy.

2.Three-wire wiring method: the positive and negative poles of the ultrasonic flowmeter are connected to the positive and negative poles of the power supply respectively, and then the signal line is connected to the signal input terminal of the controller, which can effectively avoid signal interference and improve the measurement accuracy.

3.Four-wire wiring method: the positive and negative poles and signal lines of the ultrasonic flowmeter are connected to the positive and negative poles and signal input terminals of the controller respectively, and then the output terminals of the controller are connected to the display or other equipment, and this wiring mode can realize long-distance transmission of signals, and can also avoid signal interference and improve measurement accuracy.

It should be noted that the wiring diagram of the ultrasonic flowmeter should be carefully checked when wiring to ensure that the wiring is correct and to avoid measurement errors caused by wiring errors. At the same time, attention should also be paid to the stability and reliability of the wiring to avoid problems such as poor contact or loosening.

An ultrasonic flow meter is a meter that measures flow by detecting the effect of fluid flow on an ultrasonic beam (or ultrasonic pulse).

According to the principle of signal detection, ultrasonic flowmeter can be divided into propagation velocity difference method (direct time difference method, time difference method, phase difference method and frequency difference method), beam offset method, Doppler method, cross-correlation method, spatial filter method and noise method.

Ultrasonic flowmeter and ultrasonic flowmeter are the same, because the instrument flow channel is not provided with any obstruction parts, are unobstructed flowmeter, is suitable to solve the difficult problem of flow measurement of a kind of flowmeter, especially in the large-diameter flow measurement has more prominent advantages, it is one of the rapid development of a class of flowmeter.

The ultrasonic flowmeter adopts the principle of time-difference measurement: after the transmission signal of a probe passes through the pipe wall, the medium, and the other side of the pipe wall, it is received by another probe, and at the same time, the second probe also transmits the signal and is received by the first probe, due to the influence of the flow rate of the medium, there is a time difference δt between the two, and the conversion relationship between the flow rate v and the time difference δt can be obtained according to the estimation v=(C2 2L) δt, and then the flow value Q can be obtained.

An ultrasonic flowmeter is an instrument that uses ultrasonic waves to measure the flow of fluids. The principle is to use the characteristics that the speed of ultrasonic waves propagating in the fluid is proportional to the flow rate of the fluid, and calculate the flow rate and flow rate of the fluid by measuring the time difference of ultrasonic wave propagation in the fluid.

The use of the ultrasonic flow meter is very simple, you only need to install it on the fluid pipe, emit ultrasonic waves through the sensors inside the instrument, and then receive the reflected ultrasonic signal, and calculate the flow rate and flow rate according to the time difference of the signal. Ultrasonic flowmeters have the advantages of high measurement accuracy, fast response speed, and are not easily affected by fluid properties, and are widely used in chemical, water treatment, oil, natural gas and other industries.

When using an ultrasonic flow meter, you need to pay attention to the following points:

1.Installation location: The ultrasonic flowmeter should be installed on the straight section of the fluid pipeline, and avoid being installed in the elbow, valve, etc., so as not to affect the measurement accuracy.

2.Fluid properties: Ultrasonic flowmeters have certain requirements for the viscosity, density and other properties of fluids, and it is necessary to select the appropriate instrument model according to the actual situation.

3.Cleaning and maintenance: The sensor of the ultrasonic flow meter needs to be kept clean to avoid dirt and sediment affecting the measurement accuracy.

4.Calibration test: Ultrasonic flowmeters need to be calibrated regularly to ensure measurement accuracy and stability.

In a word, ultrasonic flowmeter is a very practical flow measurement instrument, which can help enterprises achieve flow control and energy saving and emission reduction, and improve production efficiency and economic benefits.

The ultrasonic flowmeter adopts the principle of time-difference measurement: after the transmission signal of a probe passes through the pipe wall, the medium, and the other side of the pipe wall, it is received by another probe, and at the same time, the second probe also transmits the signal and is received by the first probe, due to the influence of the flow rate of the medium, there is a time difference δt between the two, and the conversion relationship between the flow rate v and the time difference δt can be obtained according to the estimation v=(C2 2L) δt, and then the flow value Q can be obtained.

Summary. Hello! Introduction to the method of ultrasonic flowmeter calibration, ultrasonic flowmeter calibration method 1, zero point calibration and zeroing When the actual flow rate is zero, the meter flow rate should also be adjusted to zero.

Usually, the zeroing is done through the auto-zeroing function. However, for high-precision measurements, you can stop the auto-zero function and set the zero deviation on the meter. In future measurements, the instrument automatically outputs this value after deducting the zero deviation.

Hello! The method of ultrasonic flowmeter calibration is carefully introduced, ultrasonic flowmeter calibration method 1, zero point calibration and zeroingWhen the actual flow is zero, the meter flow rate should also be adjusted to zero. Usually, the zeroing is done through the auto-zeroing function.

However, for high-precision wide-range measurements, you can stop the auto-zero function and set the zero deviation on the meter. In future measurements, the instrument will automatically output this value after deducting the zero deviation.

2. Damping setting: The appropriate damping setting can be used to accurately observe the process of changing the measured value or to obtain the average value of the measured value. Generally, when the automatic zeroing function is in effect, the response time obtained is about 10 times the damping setting time, and an appropriate damping time should be set to observe the real change of the measured value or the change of the measured value. Measured values, with appropriate damping.

3. Set the working parameters, and the setting of the working parameters (quantity) includes the setting of the analog output range (4-20mA); human-machine interface settings; flow rate (or speed) range setting, etc. 4. Calibration of the normal conditions of heterogeneous reflux When there is no liquid in the tube or bubbles or other abnormalities in the liquid, it can be set: keep the measured value unchanged; output cap; low yield; Zero output, etc.

At the same time, when the output accumulation pulse is added, the output is cut off, and the internal accumulation is also cut off.

Hello! The above is the method of ultrasonic flowmeter calibration.

I'm a white, I don't know much, this is adjusted after disassembly? Can it be taken apart?

How to call it slower.

Hello! As long as you close the small valve and lower the indoor temperature, the ultrasonic flow meter will slow down, because the heat consumption per minute is reduced.
