The word “turbine” is derived from a Latin word that means, “spinning thing.” The ancient Greeks ground their flour using horizontal turbine wheels. However, the idea of using a spinning rotor or turbine to measure flow did not come about until much later in history. What turbine meters have in common is the use of a rotor that spins in proportion to flowrate. Turbine flowmeters have been around for many years. In fact, the generally accepted view places the invention of the first turbine meter in 1790. However, it wasn’t until World War II and afterwards that turbine meters began being used in industrial environments. And even though turbine meters are facing competition today from new-technology flowmeters, the turbine market is still very large, and is growing in some segments.
