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.

What are the common failures caused by improper installation of ultrasonic flowmeter? Today, flowmeter manufacturer Aister meter collected the fault performance and treatment methods, and it can be collected if necessary.

Nowadays, the application of ultrasonic flowmeters is becoming increasingly widespread, and their application functions have been recognized by all aspects.

For industrial and mining enterprises with relatively old pipelines, it is advisable not to use the 2-layer acoustic layer (V method) for sensor installation. Instead, the 1-layer acoustic layer (Z method) should be selected. This installation method makes the ultrasonic waves emitted by the flow sensor of the ultrasonic flowmeter easily received by the measured flow sensor, ensuring the signal strength of the ultrasonic flowmeter’s main unit and guaranteeing high-precision measurement values.

The wiring methods of ultrasonic flowmeters mainly involve power lines, signal lines and possible communication lines, etc. The following are the detailed steps for wiring ultrasonic flowmeters based on multiple authoritative sources:

When installing ultrasonic flowmeters, the requirements for the straight pipe section are very crucial. This is mainly because the straight pipe section can ensure that the fluid flow state through the flowmeter is stable and uniform, thereby improving the measurement accuracy. The following is a detailed analysis of the requirements for the straight pipe section of ultrasonic flowmeters:

Common faults and solutions encountered in the use of ultrasonic flowmeters for sewage

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.

There are significant differences between pipe-type ultrasonic flowmeters and insertable ultrasonic flowmeters in many aspects. The following is a specific analysis of these differences

Ultrasonic flowmeter has the advantages of easy installation and maintenance and low price. So in the large pipe measurement has an unusual position, but today’s flow meter manufacturer Aister instrument Xiaobian will say that the ultrasonic flow meter is not a separate product, according to different installation methods, there are several categories. In this paper, the selection points of each different ultrasonic flowmeter are introduced in detail.

1, ultrasonic flowmeter probe used for a period of time, there will be irregular alarm. Especially when there are more impurities in the conveying medium, this problem will be more common.
Solution: Clean the probe regularly (cleaning once a year is recommended).

Correction methods for ultrasonic flowmeters are essential to ensure accurate and reliable measurements. Here are some specific correction methods commonly used in practice:

Ultrasonic flowmeters are instruments that measure fluid flow through ultrasonic technology. They have the advantages of high precision, easy installation, and non-contact measurement, and thus have a wide range of application scenarios in multiple fields. The following are some of the main application scenarios of ultrasonic flowmeters

Measuring medium: single sound conducting liquid medium

Handheld (portable) ultrasonic flowmeter with external clip-on sensing to measure liquid flow. The installation process is extremely simple, and the all-Chinese man-machine interface makes it easier to operate.

Ultrasonic flowmeters usually have high accuracy in flow measurement. Ultrasonic flowmeters are easy to install and maintain, which makes them widely used in various fields such as petrochemicals, water conservancy projects, and energy.

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

Under the premise of fixed installation conditions, ultrasonic flowmeter improves the signal processing capacity and diagnostic capacity of the flowmeter itself, and can effectively reduce noise. Under normal circumstances, the measuring accuracy of the flowmeter is very important.

Ultrasonic flowmeter in the industrial automation more and more wide range of use, many owners in the purchase of ultrasonic flowmeter, will encounter some easy to ignore in the selection of parameters, in view of this phenomenon, Aister instrument to give you a few ultrasonic flowmeter selection needs some parameters.

Ultrasonic flowmeters can generally operate normally for a long time without maintenance in the future. After that, maintenance and daily inspections are required. Not receiving the signal or having a too weak signal are both minor issues. So there’s no need to be surprised if it occurs. Just do the following steps carefully and it will be easy to solve.

External clamp-on ultrasonic flowmeters are now widely used in many fields, such as waterworks, seawater, sewage treatment plants, diesel plants, chemical plants, and so on. However, for the values measured by this instrument to be accurate, the basic condition is correct installation. So, what are the requirements for the installation of external clamp-on ultrasonic flowmeters?

Ultrasonic flowmeters are widely used for measuring the flow of liquids in various industrial applications. Like any other equipment, they may experience common faults in practical applications. Some of the common fault situations with ultrasonic flowmeters include:

Ultrasonic flowmeters can be used to measure the flow of fluids and large pipe runoff that are not easily accessible. In practical applications, if the temperature, pressure, the nature of the medium and other conditions are different from the calibration, it is necessary to calibrate the ultrasonic flowmeter, today we talk about the calibration method.

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:

The pharmaceutical and chemical industries also benefit significantly from ultrasonic flow meters. In these sectors, where precise measurement of liquid chemicals is crucial for manufacturing processes, ultrasonic flow meters offer a reliable and contamination-free solution. Their non-invasive nature is particularly advantageous when dealing with sensitive or hazardous substances, ensuring the integrity of the product while maintaining operational efficiency.

Ultrasonic flowmeter in the use of the process, encountered failures are more common, today the flowmeter manufacturer Aister meter in the form of questions and answers to make the common problems of ultrasonic flowmeter to sort out, hope to help you.

When installing the ultrasonic flow meter, it is necessary to determine the installation position first, so that the ultrasonic flow can be better measured. Today, flowmeter manufacturer Aister meter mainly makes the following explanation for the probe position selection of ultrasonic flowmeter, everyone remember to collect.

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.

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.
