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.

When it comes to ultrasonic flowmeters, it is essential to pay attention to the adaptability and requirements of installation. The main considerations include the installation direction of the flowmeter, the flow direction of the fluid, the configuration of upstream and downstream pipelines, the position of gate valves, protective accessories, pulse flow influence, vibration, electrical influence, and the maintenance of the flowmeter, etc.

The flow measurement can be completed simply by installing the sensor on the outer wall of the pipeline.

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 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:

Ultrasonic flow meters have become integral tools across various industries due to their versatility and non-intrusive nature. One prominent application of ultrasonic flow meters is in the field of water and wastewater management. Municipalities and water treatment plants employ these meters to measure the flow rates of water in pipes without disrupting the flow itself. The non-contact nature of ultrasonic technology minimizes the risk of contamination and allows for accurate measurement, contributing to efficient water distribution and conservation efforts.

The installation of the ultrasonic flowmeter is simple and convenient in the installation of all flowmeters, as long as you choose a suitable measuring point, input the pipe parameters at the measuring point into the flowmeter, and then fix the probe on the pipe. Today, flowmeter manufacturer Aister instrument makes the following analysis for you on this topic.

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:

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.

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

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

With the development of technological progress, more and more new types of instruments have been applied to the measurement of oil fields, such as ultrasonic flowmeters and mass flowmeters. Ultrasonic flowmeters have unique advantages when used for fluid measurement. They are non-contact instruments that do not change the form of the fluid, are easy to install, can measure the flow of strongly corrosive and non-conductive media, and the measurement process is not affected by physical parameters such as temperature, pressure, density and viscosity.

ultrasonic flow meters find applications in HVAC systems for measuring the flow of heating or cooling fluids. Their non-intrusive installation makes them an ideal choice for retrofits and upgrades to existing systems, allowing for accurate measurement without disrupting the infrastructure. This application contributes to the efficient operation of HVAC systems, optimizing energy consumption and ensuring optimal environmental conditions in buildings.

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.

The fixed ultrasonic flowmeter is a time-difference multi-functional ultrasonic liquid flowmeter that adopts new digital technology and is suitable for continuous measurement of full pipe liquid media.

When the user chooses the sewage flow meter and the tap water flow meter, I believe that many users will think of the ultrasonic flow meter, so why is the ultrasonic flow meter so popular?

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 in view of different installation methods, then the requirements for installation are also different, today the flowmeter manufacturer Aister meter mainly for the installation requirements of different installation methods of ultrasonic flowmeter, for you to make the following explanation.

When the ultrasonic flowmeter shows unstable signals and inaccurate readings, many users tend to think that there is a problem with the ultrasonic flowmeter sensor. However, this is not always the case. Today, we will introduce to you the reasons why the ultrasonic flowmeter sensor is good but the flow rate is low or there is no flow rate at all.

The external clamp-on ultrasonic flowmeter is a flow meter that is highly suitable for full pipe measurement in pipelines. It features easy installation, non-contact operation, and can measure the flow of large-diameter media as well as media that are difficult to contact and observe. Its measurement accuracy is very high and is almost unaffected by various parameters of the measured medium. It can especially solve the flow measurement problems of highly corrosive, non-conductive, radioactive and flammable and explosive media that other instruments cannot handle.

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 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 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.

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.
