What are the key points for using fixed ultrasonic flowmeters

Handheld ultrasonic flowmeters are widely used in industries such as water supply, heating, water conservancy, metallurgy, chemical engineering, and machinery. They can be used for production monitoring, flow comparison, temporary detection, and flow inspection, and are commonly used instruments for flow detection.

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.

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.

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 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 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 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.

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.

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.

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).

Many times when we measure the flow, we often use a more convenient handheld ultrasonic flowmeter, because the handheld flowmeter has a high accuracy and belongs to the contact measuring instrument, so we should also pay attention to the operating specifications when operating, and a lot of precautions, so today, what are the precautions for using the handheld flowmeter?

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.

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.

When measuring commonly used pipe diameters, ultrasonic flowmeters are not only cheaper than magnetic induction flowmeters, but also do not require additional engineering and piping work, and can be refurbished during continuous operation.

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.

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.

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.

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.

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

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.

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.

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.
