The difference of various kinds of fluid density meter
- Oct 09, 2018 -

   The current fluid density measurement for production logging tools mainly includes radioactive density meter, differential pressure type density meter and tuning fork density meter.

   The measurement resolution of pressure differential density meter will be reduced or even invalid when the well bore slope is large or level. And the differential pressure sensor is very easy to damage in the downhole pressure mutation.

   Radioactive density meter has some security risks and bring a lot of inconvenience due to the use of radioactive substances.

   Tuning fork density meter (fluid density inertial) is based on the principle of vibration design components, by measuring the resonant frequency of the vibrator, it can obtain the density of the fluid. It is with good stability, high reliability, able to measure the large gradient or horizontal wells.
