non-contact ultrasonic flowmeter

An ultrasonic flowmeter is an instrument that measures the flow of fluids by utilizing the propagation characteristics of ultrasonic waves. It does not require direct contact with the fluid being measured. By capturing the propagation information of ultrasonic waves in the fluid through an external sensor, it achieves non-invasive flow measurement. It has a wide range of applicable media, covering various liquids such as water, oil, and chemical solutions, as well as some gases, and is suitable for the needs of different industrial scenarios. Now let’s take a look at what the advantages and disadvantages of ultrasonic flowmeters are.

In scenarios such as hydrological monitoring and environmental protection supervision, the accuracy of flow data directly affects the scientific nature of decision-making, and rate determination is a key link to ensure the reliability of monitoring equipment data. Portable Doppler ultrasonic flowmeters, with their flexible and precise features, have become the preferred tool for flow monitoring accuracy.

Ultrasonic flowmeters, with their unique technical advantages, have been widely applied in multiple key fields:

Let’s first explore what water balance in a sewage treatment plant is: the balance of the total inflow and outflow of the sewage treatment plant. Nowadays, the issue of imbalance in the inflow and outflow of sewage treatment plants has increasingly drawn the attention of relevant regulatory authorities and various sewage operation companies. The imbalance between the influent and effluent water volumes is extremely severe, which is influenced by factors such as the sewage and sludge treatment process, the amount of reused water, the level of equipment, and the installation position of flow meters.

Handheld ultrasonic flowmeters are commonly used tool instruments for flow detection. It is designed to enhance the convenience of flow measurement. It features high measurement accuracy, a large range ratio, no pressure loss, no moving parts, and is compact and lightweight. The flow measurement can be completed simply by installing the sensor on the outer wall of the pipeline.

After the fluid passes through the elbow of the ultrasonic flowmeter, the downstream flow velocity distribution is distorted. If two adjacent planar elbow pipes are distorted, in addition to the distortion of the flow velocity distribution, vortices will also occur. This phenomenon can affect the measurement values of most types of flow meters in downstream devices (except for a few types such as volumetric ones), so it is usually necessary to install a straight pipe section of a certain length before the flow meter installation point to improve the flow situation entering the meter.

When the ultrasonic flowmeter experiences unstable signals and inaccurate readings during operation, many users tend to think that there is a problem with the ultrasonic flowmeter sensor. However, this is not always the case. Today, Aister Instruments, a flowmeter manufacturer, will explain to you the reasons why the ultrasonic flowmeter sensor is good but the flow rate is low or there is no flow rate fault.

To ensure the normal operation of ultrasonic flowmeters, property owners must choose high-quality products. When selecting ultrasonic flowmeters, property owners can judge the product quality from these aspects.

Ultrasonic flowmeters are flowmeters that measure flow by detecting the effect of fluid movement on ultrasonic beams (or ultrasonic pulses). Ultrasonic flowmeters can all be installed outside the pipe and measure flow in a non-contact manner. Their surface cost is basically independent of the size of the pipe diameter being measured, making them excellent instruments for measuring the flow of large pipes.

The accuracy of ultrasonic flowmeters in measuring fluid flow is closely related to the on-site working conditions. When selecting the position of the probe equipment, the following conditions should be met:

When installing the probe of the external clamp-on ultrasonic flowmeter, it is advisable to select the part with the finest pipe material as much as possible. The equipment area outside the pipe must be clean, and the rust and paint on the pipe surface need to be removed. If conditions permit, use a grinding machine to smooth and polish it, and then use a clean cloth dipped in acetone or alcohol to wipe off the oil stains and dust Next, apply a satisfactory coupling agent to the central part of the probe and the tube wall.

Today, we mainly talk about several common fault situations of ultrasonic flowmeters and the corresponding solutions.

Sewage ultrasonic flowmeters are favored by many users because of their ability to measure without indirect contact with the medium. However, in the daily use of the process, some users encounter the ultrasonic flow meter display is negative, this is what is going on after all?

The correct selection of ultrasonic flowmeter can ensure the better use of ultrasonic flowmeter. What kind of ultrasonic flowmeter should be selected should be determined according to the physical and chemical properties of the measured flow medium. Today, flowmeter manufacturers tell you what to pay attention to before choosing ultrasonic flowmeter

The reasonable selection of ultrasonic flowmeter model can ensure the more effective application of ultrasonic flowmeter. The choice of which type of ultrasonic flowmeter should be based on the physical and chemical properties of the measured medium to choose, so that the nominal diameter of the ultrasonic flowmeter, flow range, lining material, electrode material and output current can adapt to the nature of the measured medium and flow measurement requirements.

Everyone must master the installation method when installing the ultrasonic flow meter, if the installation error will directly cause the ultrasonic flow meter damage, today the flow meter manufacturer Aister instrument Xiaobian detail about the specific installation requirements.

Ultrasonic flowmeter in the use of the following faults, we can according to the method given in the article to solve.

Ultrasonic flowmeter installation, easy maintenance, cost-effective. However, no matter how good the flowmeter is, it also needs special attention in daily use. Otherwise, it will affect the measuring accuracy and service life of the flowmeter. Today, flowmeter manufacturer Aister meter mainly explains the maintenance and maintenance of ultrasonic flowmeters as follows.

Ultrasonic flowmeter is a non-contact instrument, so it has the advantages of simple installation and maintenance, and is very popular with customers. However, because of this advantage of ultrasonic flowmeters, it is precisely after a period of use that the signal will be weak.

The various advantages of ultrasonic flowmeter we don’t talk about today, today the flowmeter manufacturer Aister meter mainly for you to briefly introduce the ultrasonic flowmeter after the use of maintenance problems, we should not put a lot of time and money on the cost of here, I hope to help you, there is a need to collect.

External clamp ultrasonic flowmeter is a very suitable for pipe full pipe measurement flow meter, with easy installation, non-contact type, can measure the medium flow of large pipe diameter can also be used for measuring the medium that is not easy to contact and observe.

Ultrasonic flowmeter has the advantage of its working principle. In the large pipeline water flow measurement has a large proportion, today the ultrasonic flowmeter manufacturer Aister for the installation method and main points of the external clamp ultrasonic flowmeter for you to make the following explanation.

Ultrasonic flowmeters are instruments that measure flow by detecting the effect of fluid flow on an ultrasonic beam (or ultrasonic pulse). The ultrasonic flowmeter is mainly composed of an ultrasonic transducer (or an ultrasonic flow sensor composed of a transducer and a measuring tube) and a transducer mounted on the measuring pipe.

Ultrasonic flowmeter is a non-contact flow measuring instrument, which has developed rapidly in the past 20 years and has become an indispensable flowmeter in flow measuring instruments.
