Abstract
In a previous paper, the author discussed the problem of “pulsation error” of the float-type flowmeter, and gave an approximate analytical expression for the error assuming smallness of the pulsation. In the present study the same problem is pursued for large amplitude case of pulsation. The equation of motion of the float derived previously is solved by making use of a numerical method. A comparison of the resulting solution with the previous one shows that the formula for the pulsation error obtained in the previous paper can practically be applicable up to the case of fairly large pulsation. The effect of wave form (such as chopping wave, square wave and sawtooth wave) to the pulsation error is also examined.
