How Turbine Flowmeters Are Used In a Number of Industry Sectors
By: Andrew Long

Different types of turbine flowmeters have come into play since the first flowmeter was invented in 1790. Taken from the Latin meaning of "spinning thing," the Greeks would grind their flour with horizontal turbine wheels and named this piece of equipment a turbine.

These flow meters are designed to measure the flow of fluids, mainly in an industrial capacity. Chemical, refining, food processing and power plants all use turbine flow as a source of calculating the flow of liquids. As hard as technology has worked to come up with a better mousetrap, the traditional turbine flowmeter is still the most popular and dependable machine type being used today.

Although there haven't been any outstanding changes to the flowmeter, there have been additions of specific water type meters that follow the same perimeters but addressing different factors. Eight distinct kinds of turbine flow meters are used today, mainly for water billing purposes.

Lester Pelton in Camptonville, Nevada invented the Pelton wheel in 1898. At the time, this turbine was rotated by a wheel that turned as buckets of water were moved by water jets attached to the wheel's outside. The concept progressed to where it currently is with the Pelton flowmeter measuring low viscosity flows at rates of low flow.

A propeller turbine is used in hydropower and is based on the principle that the water current causes the rotation of propellers, making proportional to flow rate. Forrest Nagler was the one who designed the first fixed-bladed propeller turbine in 1916. Useful at the time because there was no electricity but is still popular today because it is so inexpensive to operate.

Another type of turbine flow meter is the Woltman. Quite possibly ahead of his time, Woltman, a German engineer published many studies on hydraulic engineering in the 1790s. Still quite popular today, the Woltman meter is best known for measuring large quantities of water used in the bulk industrial and municipal water fields.

Hydrocarbon based liquids are another form of liquid that is measured by turbine flow meters. Regularly used in the transportation industry, petroleum production and aviation, these types of meters must be very accurate and rugged due to the stress they have to withstand. Turbine meters measure utility gas, as well.

The flow of fluids has to be measured and accounted for by use of a highly dependable method. Otherwise, water companies would not know how many gallons of water were being dispensed in a certain period of time, manufacturing plants could not control the flow of liquid materials and one could not measure the flow of clean medium to high-speed liquids and gases.

New technology flowmeters are electronic rather than mechanical and serve some areas of industry and water measurement but they have yet to convince many that their trend is better than the first mechanical flowmeter designed by Woltman.
