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.

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.

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.

Ultrasonic flowmeter is cost-effective, easy to install and maintain. Today, flowmeter manufacturer Aister meter makes the following guidance for you on the installation of ultrasonic flowmeter.

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, 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.

Ultrasonic flowmeter installation, use and maintenance is simple and fast, but there are still some points can not be ignored, today the flowmeter manufacturer Aister meter for the maintenance of ultrasonic flowmeter points to make the following explanation.

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.

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.

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?

The external ultrasonic flowmeter is convenient to apply and favored by a large number of users. However, due to improper installation or debugging, inaccurate readings of the flowmeter occur from time to time. So, in general, how should we conduct self-checks?

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 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.

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

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

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.

Matters needing attention during the use of ultrasonic flowmeters

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.

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 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 installation of ultrasonic flowmeter is relatively simple and fast compared with other meters. However, the flowmeter manufacturer has to remind you that no matter how well the flowmeter is installed, it should also follow the installation requirements during the installation process.

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.

1. Reflection issue

If the object being detected is always at the appropriate Angle, the ultrasonic sensor will obtain the correct Angle. But unfortunately, in practical use, few detected objects can be detected correctly.

Several types of errors may occur among them:

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?

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.

Today, flowmeter manufacturer Aister meters and you talk about the different advantages of different installation methods of ultrasonic flowmeters.
