In industries such as food and beverage, dairy processing, biopharmaceuticals, and specialty chemicals, a flow meter must do more than measure flow. Sanitary requirements, fluid characteristics, pipeline configuration, cleaning procedures, and maintenance must also be considered. A sanitary flow meter is designed for fluid measurement in process environments where cleanliness and easy cleaning are important.…
In industrial circulating-water systems, cooling-water systems, water supply and drainage, process-water systems, and other liquid-transfer applications, stable continuous flow measurement is often required. An inline ultrasonic flow meter integrates ultrasonic transducers into a dedicated measuring pipe section, detects fluid velocity through ultrasonic signals, and calculates the flow rate. It is suitable for fixed installation and…
In industrial circulating-water systems, cooling-water systems, water supply and drainage networks, and existing pipeline applications, users may prefer not to shut down the pipeline or modify the original piping simply to install a flow meter. A clamp-on ultrasonic flow meter installs its ultrasonic sensors on the outside of the pipeline and measures flow by analyzing…
In industrial measurement of steam, compressed air, nitrogen, natural gas, and certain liquid media, users often need a compact flow meter that is convenient to install and allows flow data to be viewed directly at the measurement point. An integrated vortex flow meter combines the vortex sensor, signal-processing unit, and display/converter into one instrument assembly…
In large-diameter pipelines, industrial cooling-water systems, circulating-water systems, compressed-air networks, and other industrial applications, conventional flow meters may require a complete pipe section to be installed as part of the measuring system. An insertion flow meter uses a probe inserted into the pipeline to detect the flow condition inside the pipe, making this configuration suitable…
In laboratories, fine chemical processes, pharmaceutical equipment, gas analysis, and new-energy systems, flow rates are not always large. When the flow becomes very small, a conventional flow meter may face challenges such as insufficient resolution, unstable signals, or an unsuitable measuring range. The purpose of a micro flow meter is to accurately identify and monitor…
How should a positive displacement flow meter be selected? For oil products, lubricants, chemical liquids, and other liquids with certain viscosity, a positive displacement flow meter is a flow measurement instrument that determines flow by counting repeated fixed-volume displacement cycles.
Unlike flow meters that primarily determine flow from changes in fluid velocity, the basic concept…
How should a wedge flow meter be selected? For industrial fluids containing suspended solids, impurities, fibers, or relatively high viscosity, a wedge flow meter can be considered as a differential-pressure-based flow measurement solution.
It uses a wedge-shaped restriction to change the flow conditions inside the pipeline, creating a differential pressure between the upstream and downstream…
How should a rotameter be selected? For water, air, nitrogen, and certain industrial liquid and gas applications, a rotameter is a practical variable-area flow measurement instrument. It uses the force generated by the flowing medium to move a float inside a tapered measuring tube. Once the float reaches dynamic equilibrium, its position corresponds to the…
How should a vortex precession flow meter be selected? For natural gas, compressed air, nitrogen, and other industrial gas applications, a vortex precession flow meter is a commonly used velocity-based flow measurement solution. It is particularly useful in applications where flow measurement needs to be considered together with pressure and temperature conditions.
Proper selection requires…
How should a Venturi flow meter be selected? For water, air, steam, and various industrial liquid or gas applications, a Venturi flow meter provides a differential-pressure-based flow measurement solution. It uses changes in pipe cross-section to create a pressure difference and then determines flow according to the relationship between differential pressure and flow rate. Proper…
How should an orifice plate flow meter be selected? For steam, air, natural gas, nitrogen, and certain liquid applications, an orifice plate flow meter remains a practical differential-pressure flow measurement solution. However, proper selection involves much more than simply checking pipe size and flow rate. The medium, operating pressure, temperature, flow range, pressure-tapping arrangement, and…
