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.

The History of Variable Area Flow Meters

Exploring the History and Designs for Variable Area Flow Meters

Variable area flow meters are devices designed to measure the flow of gases or liquids through pipelines and similar enclosed structures. Over time, different types of VA flow meters have been developed, usually in response to some specific need. Here is some background on the meters and how the various designs came to pass. 

 

The Beginning

Karl Kueppers is credited with developing the first true variable area flow meter. Designed and launched in 1908, the device was patented in Germany that same year. The initial function had to do with measuring water flow. 

Felix Meyer was among the first to recognize the significance of Kueppers’ work and implemented the process for offering the meter for sale. In 1909, the firm of Duetsche Rotawerke was created in Aachen Germany. It didn’t take long for the new device to capture attention in Europe, the United Kingdom, and other areas.

In the first decades of the 20th century, Kueppers continued to refine the basic design. Specifically, he enhanced the shape of the float used in the glass tubing so that the results of the water flow testing were more accurate. 

During this period, the Kueppers product became known as a rotamesser, which can be roughly translated as a rotation measurer.

 

Here Comes the Rotameter

Prior to the Second World War, a version of the VA flow meter appeared in the United Kingdom. Still designed for measuring liquids, the newly dubbed Rotameter and registered by the UK firm of GEC Elliot. For years, the meter was manufactured by a division known as Rotameter Inc and based in the Croydon area. 

During the 1970’s the manufacturing operation was moved to Crawley, where it is still in operation. Over the years, ownership of the operation has changed as acquisitions and buyouts have taken place. As of 2016, the patent and the registration for the rotameter are held by the Yokogawa Electric Corporation.

 

Variable Area Flow Meters for Natural Gas Measurement

While originally designed for liquid measuring, further developments too place from the middle of the 20th century and continue today. Some models make use of heavy-duty plastic tubing rather than the traditional glass. The shape and materials used after 1950 for the floats have also changed. Designs that make it easier to measure the flow of gas or steam through a system serve the same basic purpose as the originals, making it easier to determine if the flow is efficient, or if some factor is impeding the progress of the gas. 

While the meters are still relatively simplistic in design, contemporary meters sometimes include equipment that makes it possible to monitor and download results to a computer program. This helps to limit the potential for human error in reading the test results. 

This more modern approach also aids in the collating of data over a specified period of time. For example, if there is the need to compare test results over the last six months and assess what differences have occurred after structural changes or other adjustments are made, accessing the history is quick and efficient. 

While variable area flow meters may be inexpensive to produce, they have saved a great deal of time and money in a number of settings. Today, the meters are no longer used exclusively in manufacturing settings. The meters are also used in managing municipal water systems, laboratories, and mining operations. There is no doubt that additional uses for the meter will come about as the technology continues to develop.

Understanding Turbine Flow Meters: A Comprehensive Guide

Flow measurement is an integral part of various industrial and engineering processes. One of the most reliable and widely used devices for this purpose is the turbine flow meter. In this comprehensive guide, we will delve into the world of turbine flow meters, exploring their working principle, advantages, drawbacks, and applications. This deep dive aims to provide you with a clear understanding of how these devices can fit into and benefit your operational needs.

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.

Pros of Turbine Flow Meters
