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.

What Are Turbine Flow Meters?

Turbine flow meters fall under the category of velocity flow meters, which operate on the principle of measuring the velocity of a fluid flowing through the meter’s pipeline, translating it into a readable volume flow rate. These meters are designed with a rotor that spins in the fluid stream. The blades of this rotor are angled to transform energy from the flow stream into rotational energy, causing the rotor to spin at a speed that is proportional to the fluid’s velocity.

The Working Principle of Turbine Flow Meters

As fluid moves through the meter’s body, it enters the turbine’s rotor section. Here, the fluid’s energy is transferred to the rotor, propelling it to spin. The speed of the spin is detected by a sensor – usually magnetic or optical – which generates an electrical signal. The frequency of this signal is directly related to the volume flow rate. By calculating the number of pulses in a given time frame, you can accurately determine the flow rate of the fluid.

How Turbine Flow Meters Work

how turbine flow meters work

Turbine flow meters are a popular way of measuring liquid and natural gas flow. Also known as an axial turbine, this type of meter consists of a turbine wheel that is placed in the stream of the flow. The flow pushes the meter’s angled blades, causing the turbine to rotate. Flow rate can be determined based on the turbine’s rotation rate once it becomes steady. The rate of rotation is typically picked up by electronic coils that are connected to the meter’s housing, and then turned into readings that can be accessed by the user.

Minimal Flow Disruption

One advantage of a turbine flow meter is that it offers minimal disruption to the flow. Because the flow can continue right through the turbine, there is little pressure loss and speed can remain fairly high. For this reason, they are often preferred for purposes water distribution, fire protection and for large commercial projects, where a high rate of flow and high pressure is desirable. On the other hand, applications where flow rates are low will typically use meters that are considered more accurate but tend to impede flow rates, such as displacement meters.

Ensuring Maximal Accuracy

Turbine meter measurements can be affected severely by factors such as flow profile, temperature and flow rate and content. Strainers installed near the meter can help protect the turbine from debris that could damage it. Depending on specific conditions, users may choose to put additional protective measures in place to ensure maximally accurate and consistent flow measurements.

New Developments

With today’s advancements in technology, turbine flow meter accuracy has also improved. Increased sensitivity allows for the precise measurement of even extremely low flow rates in some models. Manufacturers also continue to develop blade and rotor materials that are highly sensitive, durable and less vulnerable to drag and other factors that have traditionally decreased accuracy. Some types of turbine meters are also able to measure and record variations in flow with a high degree of precision. Another way in which flow meter makers have reduced inaccuracy is by reducing the rotor’s inertia. A high inertia would keep the rotor spinning fast even after flow had decreased, leading to inaccurate results. A low inertia lets the turbine reduce speed together with the flow.

Maintenance and Calibration

Regular inspection and calibration is essential to keeping a turbine flow meter accurate. For best results in calibration, test your meter under conditions that are as close to normal operating settings as possible, keeping the flow composition, rate and temperature substantially similar. In addition to regularly scheduled inspections, check your meter in the event that you are receiving inconsistent or unusual readings that cannot be explained by actual variations in the flow.

Malfunction may occur as a result of regular wear and tear, impact by debris, corrosion, or buildup of dirt or viscosity. Problems may also happen if your meter is calibrated incorrectly or was not properly installed. While some problems can be fixed by recalibrating or performing minor repairs, others may necessitate partial or total replacement. If you are using an older turbine flow meter, be aware that recent developments have substantially improved measurement accuracy; thus, it may be wise to invest in an updated model.
