Abstract:
A device determines the specific gravity of a wellbore fluid flowing into a submersible pump. The specific gravity of the wellbore fluid is determined by measuring the pressure increase across at least two pump stages and then using fluid flow properties and known pump characteristics to back calculate the specific gravity of the wellbore fluid.
