When is the ultrasonic flow meter used

An ultrasonic flow meter is a non-contact flow measurement instrument that uses the propagation velocity and reflection characteristics of ultrasonic waves to measure the flow rate and flow rate of a fluid. Ultrasonic flowmeter has the advantages of high measurement accuracy, good reliability and long service life, so it has been widely used in many fields.

The following are common applications for ultrasonic flow meters:

1.Flow measurement in industrial production: Ultrasonic flow meters can be used to measure the flow of various liquids and gases, such as water, oil, natural gas, steam, etc.

In chemical, petroleum, electric power, steel, paper and other industries, ultrasonic flow meters are widely used in flow measurement and control.

2.Flow measurement in environmental monitoring: Ultrasonic flowmeters can be used to monitor the flow of water bodies such as sewage treatment plants, sewage pipelines, rivers, lakes, etc., so as to monitor and control the pollution of water bodies.

3.Flow measurement in water conservancy projects: Ultrasonic flowmeters can be used to measure the water flow in water conservancy projects such as reservoirs, sluices, and hydropower stations, so as to rationally utilize and manage water resources.

4.Flow Measurement in Medical Devices: Ultrasonic flow meters can be used for flow measurement in medical devices, such as blood flow measurement in cardiac surgery, oxygen flow measurement in ventilators, etc.

In short, ultrasonic flowmeter has a wide range of applications in various fields, and its high accuracy, reliability and long life make it one of the important instruments in the field of flow measurement.

The ultrasonic flowmeter is a non-contact instrument, which can measure the flow rate of media with large pipe diameters and can be used for the measurement of media that are not easy to touch and observe. Its measurement accuracy is very high, almost free from the interference of various parameters of the measured medium, especially can solve the problem of flow measurement of highly corrosive, non-conductive, radioactive and flammable and explosive media that other instruments cannot.

1. The environment is harsh, the medium is special, it is inconvenient to break the pipe, the flow rate is large, and it is necessary to install, use and maintain it conveniently.

2. From the perspective of accuracy, the measurement accuracy that can be obtained by the ultrasonic flowmeter is related to the pipe diameter, and the larger the pipe diameter, the higher the accuracy that may be obtained. There are multi-channel time-of-flight ultrasonic flow meters with measuring tubes that are accurate but have a correspondingly higher level.

From the point of view, the measurement of large-diameter pipeline flow, in the clamp-mounted type of ultrasonic flowmeter, has nothing to do with the caliber, and is used to measure the flow rate of large-diameter pipelines, and the investment is more economical.

4. Starting from the measurement medium, the ultrasonic flowmeter can measure both conductive liquids, such as water, etc., as well as non-conductive liquids. The above information has been sorted out and released by Jinhu Jiete Instrument, for more ultrasonic flowmeter products, please pay attention to Jinhu Jiete flowmeter.

The main disadvantage is that the temperature range of the measurable fluid is limited by the temperature resistance of the ultrasonic transducer aluminum and the coupling material between the transducer and the pipe, and the original data of the sound transmission velocity of the measured fluid at high temperature is incomplete. At present, it can only be used to measure fluids below 200 in China. In addition, the measurement circuit of ultrasonic flowmeters is more complex than that of general flowmeters.

This is because the flow rate of the liquid in general industrial measurement is often a few meters per second, and the propagation speed of sound waves in the liquid is about 1500m s, and the change of the flow velocity (flow) of the measured fluid brings the maximum change in the speed of sound to 10 3 If the accuracy of measuring the flow rate is required to be 1%, the measurement accuracy of the sound velocity needs to be 10-5 10-6 orders of magnitude, so there must be a perfect measurement line to achieve, This is also the reason why ultrasonic flowmeters can only be applied in practice under the premise of the rapid development of integrated circuit technology.

The ultrasonic flowmeter is composed of three parts: ultrasonic transducer, electronic circuit, flow display and accumulation system. The ultrasonic emission transducer converts electrical energy into ultrasonic energy and emits it into the measured fluid, and the ultrasonic signal received by the receiver is amplified by the electronic circuit and converted into an electrical signal representing the flow rate to be supplied to the display and accumulation instrument for display and accumulation. This enables the detection and display of traffic.

Piezoelectric transducers are commonly used in ultrasonic flowmeters. It uses the piezoelectric effect of piezoelectric materials to add electrical energy to the piezoelectric element of the transmitting transducer by using an appropriate emission circuit to produce ultrasonic vibration. Ultrasonic waves propagate into the fluid at an angle, are then received by the receiving transducer and converted into electrical energy through the piezoelectric element for detection.

The transmitting transducer uses the inverse piezoelectric effect of the piezoelectric element, while the receiving transducer uses the piezoelectric effect.

The piezoelectric element of an ultrasonic flowmeter transducer is often made into a round sheet that vibrates along the thickness. The diameter of the sheet is more than 10 times the thickness to ensure the directionality of the vibration. Lead zirconate titanate is mostly used as the material of piezoelectric components.

In order to fix the piezoelectric element and make the ultrasonic wave enter the fluid at a suitable angle, the element needs to be wedged into the human voice to form the transducer as a whole (also known as the probe). The material of the sound wedge not only requires high strength and aging resistance, but also requires that the energy loss of ultrasonic waves after passing through the sound wedge is small, that is, the transmission coefficient is close to 1. The commonly used sound wedge material is plexiglass, because it is transparent and the assembly of piezoelectric elements in the sound wedge can be observed.

In addition, certain rubber, plastic and bakelite can also be used as sound wedge materials.

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.
