[0019] Working principle: When using this integrated replacement flow meter, when fluid enters the left fluid chamber 6, it pushes the diaphragm 2 to bulge into the left internal liquid chamber of the main body 1, squeezing out the liquid in the left internal liquid chamber of the main body 1. The liquid flows through the flow meter to the right internal liquid chamber of the main body 1, and the flow meter records the value. Then, fluid enters from the right fluid chamber 6. The fluid in the right fluid chamber 6 pushes the diaphragm 2 to squeeze the liquid back into the left internal liquid chamber of the main body 1. The diaphragm 2 in the left internal liquid chamber of the main body 1 squeezes out the fluid. Such repeated movements occur. During the entire operation, the liquid in the liquid chamber only circulates back and forth between the liquid chamber and the flow meter. Each circulation passes through the diaphragm 2, squeezing out the fluid in the fluid chamber 6. By using the diaphragm 2 to separate them, the liquid and the fluid are replaced in the chamber, avoiding any contact between the flow meter and the fluid. At the same time, an integrated design of the flow meter and the liquid chamber forms a main body 1 part, canceling the original joint connection. The fluid chamber 6 is fixedly matched with the liquid chamber, with a neat and integrated appearance, being convenient for installation and suitable for installation in various complex environments, greatly improving the applicability.
