Acrylic Rotameter

Product Details:

Rotometer is a variable area device. The float moves up and downward in proportion to the fluid flow rate and the annular area between the float and the tube wall. As the float rises the size of the annular opening increases ,as this area increases ,the differntial pressure across the float decreases. The float reaches a stable position when the upward force external by the flowing fluid equals the weight of the float. Every float position correspond to a particular flow rate for a particulars fluids density and viscosity.
