Abstract
A compensation device for fluidic oscillation flow meters is provided. The compensation device includes a fluid supply unit, a fluidic oscillator, an electronic valve, a reference tank and a computer. The fluid supply unit supplies fluid into a pipe. The fluidic oscillator generates a characteristic oscillation frequency when the fluid supplied from the fluid supply unit passes through the fluidic oscillator. The electronic valve controls a flow rate of the fluid passing through the fluidic oscillator. The reference tank accumulates and stores the fluid passing through the electronic valve. The computer calculates a characteristic linear compensation coefficient using data about the time for which the fluid had passed through the fluidic oscillator, an oscillation frequency of the fluidic oscillator, a preset flow rate of the electronic valve, and a preset fluid accumulation amount of the reference tank. The computer stores the calculated characteristic linear compensation coefficient.
