ABSTRACT:
An immersible instrumentation array for sampling the oil percentage, temperature and flow rate of well fluid comprising a plurality of circuit wafers, each including feedthrough connections, such wafers being arranged in an axial column having various instruments dispersed therethrough. This arrangement allows immersion of the instrumentation array into a well bore with minimal restriction to flow. To permit insertion of the array to various well depths, a single lead shielded coaxial cable attaches to the top of the array providing both the power to the various instruments and returning the measurement signals through the feedthrough connections in the wafers. To accommodate both the power signal and the measurement signals within a single lead, the signals are separated by frequency, the instrument readouts being selected in sequence by way of a pulse commutation technique.
