 FM-520 User Manual  

The FLOWMEET AI series full bore axial turbine quadmeters are the evolution of our AX series. The AX series for more than 15 years introduced more than 2,000 units to the market. This new series has a greater number of constructive options in its rotor and body materials, more options for choosing a flow computer, connection processes, measurement specifications and communication protocols.

Description of the turbine flowmeter

Turbine flowmeters consist of a vane rotor, this is the only moving part, which rotates due to the flow in the pipe. The rotor design attempts to keep flow disturbance to a minimum, taking as little energy as possible from the moving fluid. The vanes cut the fluid in a helical shape. Each revolution of the rotor, given by the longitudinal advance of the fluid, is translated into a particular volume multiplied by a scale factor of each equipment. The errors in the measurement of this equipment are given by two factors: mechanical traction effects (between the fluid and the meter components) and magnetic traction effects (originating between a pick-up coil and the rotor blades) they are a source of error. In turn, the traction effects vary with the frequency of rotation of the turbine, for this reason they represent a source of non-linearity in the frequency-flow curve of the meter.
