Abstract: Although the turbine meter principal is quite old, the actual flow turbine meter, as we know it today and which is presently employed for liquid measurement, is quite new. The modern gas turbine meter dates from about 1950. The turbine meter principle was used for gas measurement in a very crude form in Great Britain in the early I900s. These early meters were used mainly for manufactured fuel gas. This gas was relatively dirty, causing serious difficulties with rotor bearings. The meter design was usually of the anemometer type similar to instruments employed in adjusting ventilating equipment today. They were usually constructed with a vertical turbine shaft in the meter for use in a horizontal plane, with flow in an upward direction to minimize the effect of dirt. They were calibrated by adjusting openings in upstream flow passages and by deforming the blade angles. Measurement was generally at very low pressures and accuracy was very questionable.
