Abstract
A method and apparatus for determining the specific gravity of a monophasic or polyphasic fluid flowing in a conduit. The apparatus employs an square wave shaped tube known for its effectiveness in differential pressure measurements. The apparatus is configured such that the differential pressure is measured in crosswise manner Pressure taps comprising high and low pressure taps for a respective pressure sensing device are associated with a different leg. The apparatus has also been found to be effective for determining flow rate of the fluid in the conduit using differential pressure measurements.
Claims15
A device for determining the specific gravity of a flowing fluid in a conduit, comprising:
- a conduit for receiving said flowing fluid having a uniform cross section with a square wave profile, the legs of said profile being equivalent in length, each leg of said legs having a pressure sensing means;
- and
- pressure taps associated with each said pressure sensing means, said taps for a respective pressure sensing means being associated with a different leg of said legs.
