Design Study of Constant Power Type Liquid Flow Measurement

The constant power thermal mass flow meter measurement method is a very important reference for the measurement of parameters related to low fluid production wells. This paper presents an idea for the design of a constant power- based oil and water two-phase flow measurement for measuring the flow of tiny liquid flows. Experimental practice to test the flow detection characteristics of the designed constant power flow meter. The results show that this constant power thermal flow meter has good sensitivity for stable low flow measurements with a small relative error.
