Small caliber and low velocity, instrument caliber below 50mm, such as the selection of the viscosity is not sensitive to the shape of the float, the flow of the annulus at the Reynolds number can be as low as 40 to 500, then the flow coefficient tends to a constant. Rotameter for many kinds of flui

For small-caliber and low flow meter with a caliber, and the following, such as 50 mm used for viscosity is not sensitive to the shape and flow float ring gap number Renault may be as low as 40 to 500, this factor tends to flow is constant. The float of the flow meter application being tested more f

Is suitable in the small caliber and the low speed of flow, the measuring appliance caliber below 50mm, if selects to the viscosity insensitive shape float, the circulation annular space place Reynold's number may lower to 40~500, by now the discharge coefficient tended to the constant.Because the f

Applicable to small and low-flow, meter diameter below the 50mm, if you choose are not sensitive to viscosity shapes float, flow in annular gap at the Reynolds number can be as low as 40~500, when the flow coefficient tends to be constant. Due to the float type flowmeter for fluid to be measured, so
