A flow meter well tool (200) includes a volumetric well flow meter (202) to be positioned in a wellbore (102). The volumetric well flow meter (202) includes a hollow cylindrical tubing (212) to be positioned in the wellbore (102). The tubing (212) splits well fluid through the wellbore (102) into an internal fluid through the volumetric well flow meter (202) and an external fluid through an annulus between the wellbore (102) and the volumetric well flow meter (202). The hollow cylindrical tubing (212) includes an internal portion (214), where an internal cross-sectional area of the internal portion (214) is less than an internal cross-sectional area of the hollow cylindrical tubing (212). |
