Applications for a Turbine Flow Meter

Turbine Flow Meter Overview:

A turbine flow meter is a volume sensing device. As liquid or gas passes through the turbine housing, it causes the freely suspended turbine blades to rotate. The velocity of the turbine rotor is directly proportional to the velocity of the fluid passing through the flow meter.

The external pickoff mounted on the body of the flow meter, senses each rotor blade passing, causing the sensor to generate a frequency output. The frequency is directly proportional to the volume of the liquid or gas.

Either a magnetic or modulated carrier (RF) pickup can be used to sense the rotational speed of the turbine rotor.

Depending on your flow meter application, there are many types of turbine flow meters to choose from. And after understanding the application several factors come into effect when choosing a flow meter, such as:

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

If you need volumetric total flow and/or flow rate measurement, a turbine flow meter is the ideal device. Turbine flow meters are used in a wide variety of liquid and gas flow sensing applications. They can be built to endure high pressure, and high and low temperatures. They offer a high turn-down with minimum uncertainty and excellent repeatability. Turbine flowmeters are also simple to install and maintain only requiring periodic recalibration and service.

Specifications Of Turbine Flow Meter:

Accuracy is generally expressed as a percentage of true volume, measuring how close the instrument indicates actual flow.

Repeatability is determined by how well the flow meter can indicate the same reading whenever the same flow conditions exist. It also ensures quality measurement of fluids over a wide range of flow rates, temperatures, compositions and viscosities.

Depending on the type of turbine flow meter, the specifications vary.

Turbine Flow Meters: Pros and Cons

Flow measurement is critical to operations in various industries, from aerospace and aviation to pharmaceuticals and food industry. Among the numerous flow measurement devices available, turbine flow meters stand out for their precision and reliability. In this post, we’ll delve into the advantages and disadvantages of turbine flow meters to help you determine if they’re the right choice for your application.

Pros of Turbine Flow Meters

High Accuracy and Repeatability

Turbine flow meters are prized for their high level of accuracy. They are capable of providing precise measurements of liquid flow, especially in clean, low-viscosity fluids. The repeatability of these devices is excellent, meaning they can produce consistent results under similar conditions, which is crucial for quality control and operational consistency.

Wide Range of Applications

These flow meters are versatile and can be used across a wide spectrum of applications. Whether it’s for water, petrochemicals, or food production, turbine flow meters can handle various fluids with ease. Their ability to work with a range of temperatures and pressures also makes them suitable for diverse industrial settings.

Fast Response Time

The response time of turbine flow meters is nearly instantaneous. They can quickly adapt to changes in flow rate, making them suitable for applications where flow conditions are expected to fluctuate.

Easy to Maintain

Turbine flow meters have relatively few moving parts, which minimizes the potential for wear and tear. Maintenance, when required, is generally straightforward, ensuring minimal downtime for your operations.

Cons of Turbine Flow Meters

Sensitivity to Flow Profile and Fluid Properties

While turbine flow meters are versatile, their accuracy can be significantly affected by changes in the flow profile or fluid properties. Swirling flows or pulsating pressures can lead to measurement inaccuracies. Additionally, flow meters are best suited for clean liquids, as particulates or sediment in the fluid can damage the turbine blades.

Risk of Wear and Tear

The moving parts within a turbine flow meter, although few, are subject to wear over time, especially when used with abrasive fluids. This can lead to a gradual loss of accuracy and the need for recalibration or replacement.

Installation Requirements

Proper installation is key to the accurate functioning of turbine flow meters. They require a straight run of pipe upstream and downstream of the meter to ensure a stable flow profile. Inadequate installation space or improper setup can lead to inaccurate readings.


While turbine flow meters offer high accuracy, they can also come with a higher price tag compared to some other flow measurement technologies. This initial investment may be a consideration for some operations.
