'''Helical Flow Meter''' has rotor scrolls which accept and release continuous flow. While the flow is being transported through the centre portion of the meter, it is trapped by the flights of the scrolls, these form positive displacement pockets. Smooth flow is assured and no pulsation is created by the meter itself. A sensor detects the motion of the rotor and produces a high resolution pulse output. | |||
Helical flow meters get their name from the shape of their gears or rotors. These rotors resemble the shape of a helix, which is a spiral-shaped structure. As the fluid flows through the meter, it enters the compartments in the rotors, causing the rotors to rotate. Flow rate is calculated from the speed of rotation. | |||
Helical flow meters are [[Positive Displacement PD Meters]] with a very favourable pressure drop behaviour. They are therefore perfectly suited for the flow measurement of very high viscosity fluids. | |||
