Abstract :
In order to acquire higher sensitivity and stability for the Differential Pressure (DP) flowmeter, the structure and size were optimized on the DP flowmeter. Throat throttle, straight pipe and Venturi tube, the three types of DP flowmeter were contrasted and analyzed. The Venturi tube type is the most sensitive. The relation between inner diagram and flow rate was analyzed and calculated for micro-flowmeter, an optimum range of flow rate for a certain inner diagram pipe is ascertained while fluid flowing stably.
