How much does a metal rotor flowmeter cost

Metal float/rotor flowmeter LZZ/LZD

Metal float/rotor flowmeter LZZ/LZDIt is actually a variable area flowmeter. The metal float (rotor) flowmeter LZZ/LZD typically has an upright conical tube and a float that can freely move up and down with the flow rate. When the fluid flows through the conical tube from bottom to top, the thrust S generated by the kinetic energy of the fluid on the float and the buoyancy A of the fluid cause the float to rise. As the circulating area between the inner wall of the cone tube and the float increases, the thrust S generated by the fluid kinetic energy on the float decreases accordingly. When the sum of thrust S and buoyancy is equal to the float's own gravity G, the float is in equilibrium and stable at a certain height. The scale corresponding to this height position indicates the flow rate through the flowmeter.
