Metal rotor flowmeter
Thread Content
With the same pipe diameter and water as the medium being measured, but different measurement ranges, do the rotor shape and size also differ?
For a given medium and conditions, the selection of a rotameter involves two aspects: one is the selection of the cone tube, and the other is the selection of the float or rotor. Generally, large flowmeter manufacturers can produce cone tubes in standard specifications, but by using rotors of different specifications, it is possible to adapt to various measurement ranges, as well as to different media and operating conditions.
It depends. There are three ways to determine the range of a metal rotor flowmeter: 1. Changing the taper of the cone ； 2. Change the shape or weight of the rotor ； 3. Capture the effective stroke of the rotor. For example: set the position where the rotor rises to 2/3 as the full scale, so that both the indication and output are 100% at this point. Doing this may result in a loss of some measurement accuracy, but the same gauge can cover several ranges.
Just say it’s different, that’s all:D:D:D
It’s definitely different; it must also have something to do with the mass of the rotor
