Study on the flowmeter with orifice mounted inside

The problens existing in the process of using conventional instrument to measure the small and micro flowtherough the small - bore pipes ,togather with the developingstatus , working principles of the orififce inner - mountedflowmeter and the factors affect flow coefficient is introduced and anayzed in thes paper. The field applicationsshow that it is the ideal instrument for the measurement ofthe small and mocro , flow of small - bore pipes.
