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 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.

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.

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 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.

In the face of many types of ultrasonic flowmeters, users should choose a reasonable selection according to the actual situation and measurement needs. Today, the flowmeter manufacturer Aister meter gives you a detailed introduction to the selection of ultrasonic flowmeters with different installation methods.

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 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.

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.

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 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 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.

After having a corresponding understanding of the working principle and application of the ultrasonic flowmeter, what we now need to understand is that in its application of a variety of occasions and various fields to measure user flow, and after the application, we will have to do maintenance for it?

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.

Ultrasonic flowmeters, as very important flow measurement devices in various industrial fields, have a particularly significant adverse impact on measurement accuracy due to their sensors. Different types of sensors should be selected based on the differences in application environments. Today, Aister Instruments, a flowmeter manufacturer, will provide the following explanations regarding several different sensors.

Advantages of ultrasonic flow meter

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 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.

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.

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.

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.

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.
