Fluid Flow Sensor | Types and Product List

Fluid Flow Sensor refers to a type of instrument used to measure the flow rate or quantity of moving gases, steam, liquids or solids. Therefore, in terms of medium classification, we can divide Fluid Flow Sensor into 4 major categories. Used to measure and monitor the flow of gases, steam, liquids or solids respectively.

Fluid Flow Sensors for Steam

There are two types of steam: saturated steam and superheated steam. And measuring steam also involves high temperature, temperature and pressure compensation, etc. Therefore, when you choose a steam flow meter, please be sure to inform us of these parameters.

We also supply Steam Pressure Sensor/transducer for Industrial Steam Measurement.

Fluid Flow Sensors for Liquids

Flow sensor selection for liquids is more complex than for gases and vapors. Because pipe diameter, flow rate, pressure, High temperatures, extremely low temperatures, viscosity, chemical properties, etc. will all affect the selection of Fluid Flow Sensors models.

You can refer to our “Flowmeter Selection Guide | Find the Best One for Your Application” and follow the steps to slowly select the appropriate model.

Typical uses include coal injection pipelines in ironmaking blast furnaces, coal injection pipelines in thermal power generation boilers, total process transportation volume monitoring, various fuel boilers and other productive powder flow monitoring.

What is a Flow Sensor / Flow Meter?

Flow Sensor / Flow Meter is an instrument used to measure the flow rate of a fluid, such as a liquid or gas. The basic function of a flow meter is to measure the flow rate of a fluid.

This is critical for many industrial processes, as changes in flow rate may affect production efficiency and product quality.

In many industrial applications, flow meters are combined with control systems to monitor and regulate the flow of fluids in real time to ensure the stability and safety of the production process.

Types of Flow Sensors: by different operating principles

The content above this article classifies flow meters/flow sensors according to different media types. Then we can also classify flow sensors according to different measurement principles. From their names, you can see their working principles. Common classifications are as follows:

Electromagnetic flowmeter. Used to measure the flow of various conductive liquids. Mostly used to measure water, wastewater, sewage, acid and alkali solutions, etc.
Turbine flowmeter. Used to measure the flow of various clean liquids. Mostly used for low-viscosity liquids such as beer and diesel.
Vortex flowmeter. Used to measure the flow of various gases, liquids, or steam.
Ultrasonic flowmeter. Used to measure the flow of clean and impurity-free liquids.
Positive displacement flowmeter. Including spiral rotor, dual rotor, oval gear, spur gear flowmeter, etc. Used to measure the flow of various oils and high-viscosity liquids.
Differential pressure flowmeter. Used to measure the flow of various gases, liquids, or steam.
Coriolis mass flowmeter. Highest measurement accuracy. Used to measure the mass flow of liquids or gases under various conditions.
Thermal mass flow meter. Dedicated to measuring the flow of dry gases.
Solid powder flow meter. Based on electrostatic measurement technology. Dedicated to measuring the mass flow of various powders.

Benefits of Flow Sensors / Flow Meters

Process monitoring: In the industrial field, flow meters are indispensable “monitors” in the production process.
Data recording: Flow meters can record flow data to help companies conduct production analysis, cost control and energy consumption management.
Quality control: In industries such as food and chemicals, accurate measurement of flow meters helps ensure product consistency and quality.
Environmental monitoring: Flow meters are also used to monitor the flow of water and gas to assess environmental impact and resource management.
