Turbine Flow Meter Overview

A turbine flow meter is a device used to measure the volume of liquid or gas passing through it. When fluid flows through the meter's housing, it spins the suspended turbine blades. The speed of the turbine rotor matches the speed of the fluid, providing a direct measurement of the fluid's velocity.

Overall, turbine flow meters offer a cost-effective solution for measuring fluid flow in a wide range of industrial

An external sensor, mounted on the flow meter's body, detects each passing rotor blade and generates a frequency output. This frequency corresponds directly to the volume of fluid moving through the meter. The sensor can be either magnetic or use a modulated carrier (RF) pickup to track the turbine's rotational speed.

Choosing the Right Turbine Flow Meter

Selecting the appropriate turbine flow meter depends on your specific application and several key factors, such as:

• Fluid Type
• Viscosity
• Connections
• Pipe Sizing
• Process Temperature (min & max)
• Flow Range (min & max)
• Pressure Range (min & max)
• Accuracy Range
• Specific Applications

Turbine flow meters are ideal for measuring both total flow and flow rate. They are versatile, suitable for various liquid and gas applications, and can withstand high pressures and extreme temperatures. With a high turndown ratio, minimal uncertainty, and excellent repeatability, these meters are also easy to install and require only periodic maintenance and recalibration.

Specifications of Turbine Flow Meters

The accuracy of a turbine flow meter is usually expressed as a percentage of the true volume, indicating how closely the meter's readings match the actual flow. Repeatability measures the meter's ability to produce the same reading under identical flow conditions, ensuring consistent fluid measurement across a range of flow rates, temperatures, compositions, and viscosities. Specifications can vary depending on the type of turbine flow meter.
