Fuel Oil Dynamic Flow Standard Device and Its Application

摘要

This paper introduced a piston-type dynamic flow standard device and the method for applying step flow rate to the turbine flowmeter. seting up math model of the turbine flowmeter and analyzing the dynamic parameter (step response time constant)and things that affect dynamic performance of the flowmeter in theory, acquiring the step flow response data of the flowmeter by experiment and calculating the time constant. the reality result is consistent with theory.
