Non-contact Flow Meters

Non-contact flow meter for measuring hard-to-reach and unobservable fluids and large pipe flows. It is linked to a water level meter to measure open water flow. The use of ultrasonic flow ratio does not require the installation of measuring elements in the fluid, so it does not change the flow state of the fluid, does not produce additional resistance, the installation and maintenance of the instrument does not affect the operation of the instrument production line, it is an ideal energy-saving flow meter.

1. ultrasonic flowmeter is a non-contact measurement instrument, can be used to measure the fluid flow and large pipe runoff that is not easy to contact observation. Does not change the flow state of the fluid, does not produce pressure loss, easy to install.

2. can measure the flow of strong corrosive media and non-conductive media.

3. Ultrasonic flowmeter measurement range, pipe diameter range from 15mm to 6m.

4. Ultrasonic flowmeter can measure the flow of various liquids and sewage.

5. ultrasonic flowmeter measured volume flow rate is not affected by the temperature of the flowing body, pressure, viscosity, density and other thermal physical parameters. It can be made into fixed and portable forms.

At present, industrial flow measurement prevails in large pipe diameter, large flow measurement difficulties, this is because the general flow meter with the increase in the diameter of the measurement pipe will bring manufacturing and transportation difficulties, increased costs, increased energy consumption. Losses will increase, and the installation of not only these disadvantages, ultrasonic flowmeter can be avoided.

As all types of ultrasonic flowmeter can be installed outside the pipeline, non-contact flow measurement, the cost of the instrument and the measured pipe diameter is basically irrelevant, while other types of flowmeter with the increase in pipe diameter, the cost increases significantly, so the ultrasonic flowmeter caliber than the same function of other types of flowmeter the larger the function of the more superior cost-effective. Considered to be a better large pipe runoff measurement instruments, and Doppler ultrasonic flowmeter can measure the flow of two-phase media, so it can be used for sewage and sewage and other dirty flow measurement.

In power plants, the use of portable ultrasonic flowmeter to measure turbine feed water, turbine circulating water and other large pipe diameter flow more convenient. Ultrasonic flow juice can also be used for gas measurement. Pipe diameter applications range from 15mm to 6m, from a few meters wide nullahs, culverts to 500m wide rivers.

In addition, ultrasonic measuring instruments flow measurement accuracy is almost independent of the measured flow body temperature, pressure, viscosity, density and other parameters, and can be made into a non-contact, portable measuring instruments, so it can be solved to solve the other types of instrumentation is difficult to measure the strong corrosive, non-conductive, radioactive and flammable and explosive media flow measurement problems. In addition, in view of the characteristics of non-contact measurement, coupled with a reasonable electronic circuit, a meter can be adapted to a variety of pipe diameter measurement and a variety of flow range measurement. The adaptability of ultrasonic flowmeter is also incomparable to other instruments. Ultrasonic flowmeter has some of the above advantages, so more and more attention and to the product series, generalization of the direction of development, has been made into different channels of the standard, high-temperature type, explosion-proof, wet instrumentation to adapt to different occasions of the media, different occasions and different pipeline conditions of flow measurement.

Applications of Non-Contact Flow Meters

Oil and Gas Industry: Used for monitoring crude oil flow, refined petroleum products, and gas pipelines without risking leaks or contamination.

Water and Wastewater Management: Deployed in treatment plants and distribution systems to measure water flow in large pipes and open channels.

Chemical Processing: Ideal for handling corrosive chemicals and hazardous materials without exposing sensors to harsh environments.

Food and Beverage Industry: Ensures hygiene by measuring the flow of liquids such as milk, juices, and other beverages without direct contact.

Pharmaceutical Industry: Supports the precision required in drug manufacturing and sterile processing.

Non-contact flow meters offer a highly impelling solution for industries requiring accurate, contamination-free, and low-maintenance flow measurement. With a range of technologies available, selecting the right meter depends on fluid properties, application requirements, and budget considerations. As technology continues to evolve, non-contact flow meters will play an increasingly vital role in industrial automation and process optimization.
