Abstract: A method of correcting for overspin in a turbine meter is provided. The turbine meter has turbine rotors positioned in a pipe in which liquid passes therethrough. The turbine rotors rotate in response to movement of the liquid passing through the pipe and sensors mounted proximate thereto count each passage of a rotor by providing an electronic pulse to a microprocessor. The microprocessor calculates the frequency of the electronic pulses which is directly proportional to the total quantity of liquid passing therethrough. If the microprocessor detects a rapid decrease in the frequency of the electronic pulses from the one or more sensors, it begins storing the frequency data therein. The microprocessor determines whether the decrease is due to a total shut off of liquid flowing or to a slow down of said flow. If a slowdown, the stored frequencies are used to compute the total quantity flowing through said pipe. If a shut down, the stored frequencies are deleted and not used to calculate total frequency.
