Featured Clamp-on ultrasonic flow meters

Handheld Ultrasonic Flow Meter is a commonly used clamp-on ultrasonic flow meter.

Clamp-on ultrasonic flow meter mainly refers to the installation form of the ultrasonic sensor. The sensor clamp is fixed outside the pipe.

Clamp-on ultrasonic flow meters can be handheld, wall-mounted, and portable with printing functions depending on the host. You can select different hosts according to your measurement needs.

Typical Applications of Handheld Ultrasonic Flow Meter

The handheld ultrasonic flow meter is mainly used for flow measurement of industrial pipeline fluids, and is widely used in environmental protection, petrochemical, metallurgy, paper-making, food, pharmaceutical and other industries.

The SI-2000H ultrasonic flow meter is ideal for flow testing during test and balance.

It is also useful for temporary flow monitoring, in existing systems to establish baseline demand data.

  • Water (hot water, cooling water, potable water, seawater, etc.)
  • Petroleum products
  • Chemicals, including alcohol, acids, etc
  • Beverage, food, and pharmaceutical processors
  • Secondary sewage, waste treatment, etc.
  • Power plants, Metallurgy, and miming applications
  • Pipeline leak detection, inspection, tracking, and collection

Of course, if you are allowed to install a pipe segment flowmeter in your measurement pipeline, you may consider the use of an electromagnetic flowmeter. Electromagnetic flowmeters will provide more accurate measurements.

For example, if you need to measure the wastewater flow of a 2-inch pipe, then you can refer to: Magnetic Flow Meters Guides.

Portable ultrasonic flow meter for water

Ultrasonic flowmeter is especially suitable for measuring large-diameter liquid pipelines because of its measuring principle. It has a large number of applications in urban water supply and sewage treatment industries. And the measurement results are very good.

Water is often used as circulating water in industrial production. That is, the water that can be recycled as the carrier of heat in the production process of the enterprise. The beginning is a circulating pool with a cooling system, and the end is the heat exchange equipment of the production workshop.

There are many types and quantities of heat exchange equipment in biochemical companies, so the circulating water pipelines are complicated. If a flow meter is installed on each circulating water pipeline, it will be a considerable expense.

Therefore, most production companies do not install flow meters for circulating water pipes in the initial stage of design to reduce investment costs. However, in order to grasp the operating efficiency of all heat exchange equipment in the production process, it is necessary to detect the flow rate of the circulation in the pipeline. .

An ultrasonic flowmeter can be used as a standard meter to transmit the value. It not only protects water resources rationally and scientifically, but also quantifies the paid use of water resources to a great extent. At the same time, it also protects the interests of both parties who use the water and reduces the cost of enterprise inspection. This makes periodic verification of large-caliber water flow meters a reality.

Handheld ultrasonic flow meter manual:

The measurement accuracy of the ultrasonic flowmeter is very high. Almost no interference from various parameters of the measured medium. In particular, it can solve the flow measurement problems of strong corrosive, non-conductive, radioactive and flammable and explosive media that other instruments cannot.
So what causes the inaccurate measurement of the ultrasonic flowmeter? The following are the reasons for the inaccurate measurement:
The influence of pipeline parameter equipment on the accuracy of ultrasonic flowmeter measurement.
The influence of upstream and downstream straight pipes on the accuracy of ultrasonic flowmeter measurement.
The influence of couplant on measurement accuracy.
The influence of the installation position of the ultrasonic flowmeter transducer on the measurement accuracy.

Common types of ultrasonic flow meters
①According to the measurement principle. Ultrasonic flowmeters are now the most commonly used methods for measuring flow rates are the propagation velocity difference method ultrasonic flowmeter and the Doppler frequency shift method ultrasonic flowmeter. The propagation velocity difference method can be divided into three types: time difference method, phase difference method and acoustic cycle frequency difference.
②According to the installation method of the transducer. There are two types of ultrasonic flowmeters: fixed ultrasonic flowmeter and portable ultrasonic flowmeter.
The transducer installation methods of the fixed ultrasonic flowmeter can be divided into:
A tube-segment ultrasonic flowmeter integrating transducer and measuring tube;
The external clamp ultrasonic flowmeter with the transducer clamped on the outer wall of the measuring tube;
Plug-in ultrasonic flowmeter in which the transducer passes through the outer wall of the pipe and directly contacts the medium;
The transducer is attached to the inner wall of the large pipeline ultrasonic flowmeter.
③According to the channel of propagation. Ultrasonic flow meters can be divided into single-channel ultrasonic flow meters and multi-channel ultrasonic flow meters. Among them, multi-channel can be divided into two-channel ultrasonic flowmeter, ultrasonic flowmeter, four-channel and eight-channel ultrasonic flowmeter.
Extended Reading: Inline Ultrasonic Flow Meter

Ultrasonic flowmeters use sound waves to determine the velocity of a fluid flowing in a pipe.
At no flow conditions, the frequencies of an ultrasonic wave transmitted into a pipe, and its reflections from the fluid are the same.
Under flowing conditions, the frequency of the reflected wave is different, due to the Doppler effect.
When the fluid moves faster, the frequency shift increases linearly.
The transmitter processes signals from the transmitted wave, and its reflections to determine the flow rate.

Portable Ultrasonic Flow Meter is a handheld ultrasonic flow meter. The clamp-on sensor is used to measure liquid flow in industrial pipelines.

The portable ultrasonic flowmeter uses a non-invasive sensor to measure liquid flow. The installation process is extremely simple. There is no need to destroy the pipeline during the measurement process and no need to stop production. The sensor is not in contact with the measured medium. Battery powered, small size, light weight and easy to carry. Realize the real sense of mobile flow measurement, online detection, is a real sense of portable ultrasonic flowmeter.

Generally speaking, mass flow meters are relatively accurate.
Of course, the accuracy of the flowmeter still depends on the site conditions.
If the measurement of temperature and pressure is not very difficult, the accuracy of the flowmeter must be relatively high.
In addition, to ensure the accuracy of the flowmeter, correct installation and use are also very important.
