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…
If you are selecting a turbine flow meter, the direct recommendation is this: do not focus only on the pipeline diameter and connection. You should first confirm the measured medium, flow range, viscosity, temperature, pressure, pipeline conditions, and installation environment.
A turbine flow meter can be used for liquid flow measurement under suitable operating conditions.…
For users searching for an ultrasonic flow meter, the direct answer is this: the right selection should begin with the measured medium, pipeline diameter, flow range, installation method, pipe material, temperature, pressure, and measurement requirements. One important advantage of ultrasonic flow measurement is that suitable configurations can be selected for different pipeline applications, including situations…
If you are selecting a thermal gas mass flow meter, the first things to confirm are the gas being measured, actual flow range, operating pressure and temperature, gas composition, pipeline conditions, and installation environment.
A thermal gas mass flow meter measures gas flow through the heat exchange relationship between the gas and heated sensing elements.…
For users searching for an imported Coriolis mass flow meter, the direct answer is this: if your application requires direct mass flow measurement and also needs to monitor parameters such as density, temperature, or volume flow, a Coriolis mass flow measurement solution can be considered according to the actual process conditions. The key selection factors…
For users looking for an imported electromagnetic flow meter, the direct answer is this: the correct selection should start with the conductivity of the liquid, flow range, pipeline diameter, pressure, temperature, lining requirements, electrode material, and installation conditions. An electromagnetic flow meter is designed for conductive liquid measurement, but different industrial media and operating environments…
