摘要
In order to compensate the hydrodynamic pressure on the turbine of a flowmeter, means are provided to create a zone of reduced pressure of constant value upstream of the turbine hub, together with means for creating a zone of pressure, on the downstream face of the hub, varying in a defined manner as a function of the axial position of the turbine. The pressure difference thus created on either side of the turbine hub produces a reaction force tending continuously to balance the hydrodynamic pressure of the fluid whatever the flow rate. The invention is particularly applicable to high flow rate water meters.
