Mud logging using paddle type flow out sensor 20ma

The sensor is used to real time inspect the flow out of mud, so it provides a basis for optimized and safe drilling. According to the linear equation of liquid, the Bernoulli principle and the force analysis, the functional relation between flow out and angular displacement of mudguard can be acquired. Consequently, once the angular displacement is acquired, the flow out can be measured immediately.
