Abstract
A meter which measures fluid flow by passing the fluid through a receptacle and determining the mass of fluid in the receptacle. The shape of the receptacle, the fluid flow path within the receptacle and the receptacle outlet are chosen to ensure that for a selected fluid the mass of fluid in the receptacle is a linear function of fluid flow rate. The mass is determined by weighing the receptacle. Total mass flow is determined by integrating the mass measurement over time if particular application of the meter is as a milk meter.
Claims20
Apparatus for measuring flow rate of a fluid comprising, a chamber, an inlet to said chamber, an outlet from said chamber, and means for determining the mass of fluid in the chamber, said chamber and/or at least part of the fluid flow path through the chamber having a shape such that the flow rate of a selected fluid through said chamber, entering through said inlet and exiting through said outlet is in a substantially linear relationship to the mass of fluid in said chamber and the fluid flow rate through said chamber is substantially a linear function of the mass determined by said means.
A method of measuring flow rate of a fluid comprising the steps of passing fluid through a chamber, said chamber and/or at least part of the fluid flow path through the chamber being shaped such that the flow rate of a selected fluid is in a substantially linear relationship to the mass of fluid within said chamber, and determining the mass of fluid in said chamber, the fluid flow rate being substantially a linear function of determined mass.
