What Is a Turbine Flowmeter?
A turbine flowmeter measures the flow rate by the rotation of an impeller within a pipe, typically applied to liquids in industrial and process control settings. Known for high measurement accuracy, especially in moderate to high flow ranges, turbine flowmeters have wide flow range capabilities and are durable across various fluid types and conditions. However, they are not suitable for viscous fluids or those containing solids.
Uses of Turbine Flowmeters
Turbine flowmeters find applications across several industries:
1. Petroleum Industry
Used in oil and gas distribution, refining processes, and trade metering, turbine flowmeters provide precise measurements essential in these sectors.
2. Food and Beverage Industry
In food processing and beverage manufacturing, they are integral for controlling metering and mixing processes and dosing food additives.
3. Heating and Air Conditioning Industry
Turbine flowmeters in heating and cooling systems ensure proper heat exchange by measuring water or refrigerant flow rates, contributing to energy efficiency and comfort.
Principle of Turbine Flowmeters
The operating principle involves an impeller rotated by fluid force, with rotational speed correlating to the volumetric flow rate. Speed is detected by sensors or magnetic elements, with data converted to flow rate by computers or displayed on units for monitoring and control.
Types of Turbine Flowmeter
Turbine flowmeters are categorized based on impeller type:
1. Axial Impeller Type
Fluid flows axially through the turbine blades, offering a compact design, high accuracy, and responsiveness.
2. Tangential-Flow-Impeller Type
With impellers arranged in an arc, the fluid flows tangentially, transferring kinetic energy to generate rotation. These meters are robust, durable, and ideal for high flow ranges.
