About Rotameter

Principle of Rotameter

Whenever liquid or gas moves through a taper tube containing a buoy, a weight contrast of P1 and P2 is made in the middle of upper and lower side of the buoy. The buoy moves upwards by a power got by increasing the weight differential by the most extreme cross sectional range of the buoy.

Because of taper end of the tube, as the buoy moves upwards, the liquid passing zone increments as a consequence of which the differential weight diminishes. Upward development of buoy stops when the dead load is progressively adjusted by the differential weight. Decreasing of metering tube is designed to the point that the vertical development of the buoy turns out to be straightly corresponding to the rate of stream and the scale is given to peruse the position of the buoy, in this way bringing forth stream rate sign.

In light of Bemoulli's hypothesis, the standard said above can be hypothetically communicated as follows:

Advantages of Rotameter  

Used to measure the flow rate of gases & liquid, Rotameter used in multiple industries due to its following advantages:

Rotameter Selection Criteria
