Is the float meter the same as the rotor flowmeter?
Float is a float in a vertical large small conical pipe (also called rotor), the measured fluid drives the float moves up and down, while changing the flow area of annular float with the pipe wall, when the float pressure difference is equal to the weight of the float when the float position is stable, by the float position flow can be obtained.
By changing the flow area to detect flow flowmeter, float type, plunger type piston and piston type three forms, which is seldom used, other two kinds of float type, plunger type are often called rotameter or rotor flowmeter. But the float is known as the "float" flowmeter, and the "slug" is known as the "rotor flowmeter" in the majority.
Plunger type is provided with an annular orifice in a cylindrical pipe with a vertical plate, is provided with a large small conical rotor (or float), measured fluid to drive the rotor to move up and down, while changing the flow area of the rotor and the annular ring of pore plates, when the rotor under the pressure difference in the weight of the rotor when the rotor position, the rotor position can be obtained by flow.
