tokyo keiso rotameter water flow meter

rproduct description:

LZS plastic rotor flowmeter and LZB-S plastic float flowmeter is the same product, different names.

The main measuring element of the rotor flowmeter is a vertically-mounted lower small upper large-cone glass tube and a float that can move up and down inside. When the fluid from bottom to top through the tapered glass tube, the float pressure drop between the upper and lower, the float in the differential pressure rise. When this rising force, buoyancy and viscous buoy lift force equal to the gravity of the float, the float in a balanced position. Therefore, there is a certain proportional relationship between the fluid flow through the glass rotameter and the float rising height, ie, the flow meter area of the glass rotameter, and the height of the float can be used as the flow measure.
