Background

As is well known, the main measuring elements of a glass rotameter are a conical glass tube mounted vertically, small at the bottom and large at the top, and a float that can move up and down inside the tube. When fluid flows through the conical glass tube from bottom to top, pressure difference is generated between the upper part and the lower part of the floater, and the floater rises under the action of the pressure difference. When the rising force, buoyancy and viscous lift are equal to the weight of the float, the float is in equilibrium. Since the flow rate of gas through a glass rotameter is proportional to the rise height of the float, the height of the float position can be a measure of the flow rate.

When glass rotameter was external pipeline again in current life, generally all used simple screw thread mode to connect, though the assembly of being convenient for, receiving external circumstances such as rocking to influence down, the not hard up condition appears easily in the screw thread subassembly, and the leakproofness is not good, appears leaking the condition when serious.
