ABSTRACT:
A meter system and method for measuring the velocity and metal concentration of a fluid containing a gamma ray absorbing metal isotope flowing in a pipe. The meter system comprises a radioactive source of gamma rays which is oscillated in a direction angled to the fluid flow, an accelerometer device incorporated with the gamma ray source, gamma ray detector means located adjacent a pipe portion for detecting the presence of a metal isotope in the flowing fluid, and an electrical circuit and meter means arranged for measuring and displaying the velocity of the oscillating source of gamma rays when the metal isotope in the flowing fluid is absorbing gamma radiation. If desired, the concentration of gamma ray absorbing isotopes such as iron compounds contained in the flowing fluid can be monitored by a counter means to measure the metal concentration of the fluid, or ash concentration of a flowing coal-derived liquid.
