Sensor device and System for online Measurement of the superficial gas Velocity, depth of foam, apparent density and Holdup in flotation cell

摘要

The present Invention relates to the field of Measuring Devices, More specifically to the pressure and Flow Measuring Devices, as well as derived quantities,And in particular provides a sensor Device for online Measurement of the superficial gas Velocity, depth of foam, apparent density and Holdup in Flotation cells.It is characterized in that it comprises: a First Tube that has a first upper portion, a Lower portion and a First Channel and a Second TubeInsert in the first Channel of the first Tube, which has a Second Upper portion, a Lower portion and a Second Shaft Second InternalThe Second Tube has a length greater than the first Tube; a First Valve connected to the first upper portion of the first Tube, a Second Valve connected to the secondTion of the second Upper Tube; a First Pressure gauge connected to the first upper portion of the first Tube, a Second Pressure gauge connected to the second Upper portion ofThe Second Tube; a First Mass Flow Meter connected to the portion of the first Valve to be opposed to the first Tube; and a Second Mass Flow Meter connected to the portion ofThe Second Valve which is opposed to the second Tube. The present Invention also provides the system for online Measurement of the gas superficial velocity in Flotation cells.
