Flow Calibration Technician

The Flow Calibration Technician performs calibration, verification, troubleshooting, and repair of inspection, measurement, and test equipment (IM & TE) used for liquid-flow measurement. The technician applies metrology principles, fluid-measurement fundamentals, mathematics, and measurement science to ensure accurate and traceable flow measurements. The technician operates liquid-flow calibration systems and reference standards, selects appropriate calibration methods and test points, evaluates measurement data and uncertainty, identifies out-of-tolerance conditions, and documents results in accordance with SCI quality-system and accreditation requirements.

• Calibrate, verify, troubleshoot, and, when authorized, repair IM & TE used for liquid-flow measurement to ensure compliance with published specifications and applicable procedures.
• Maintain primary and/or intrinsic calibration standards.
• Maintain secondary and/or working calibration standards.
• Collect, compile, measure, summarize, and record data gathered during calibration.
• Analyze measurement data for identifying abnormalities trends and/or predicting future values.
• Identifying IM & TE out-of-tolerance conditions and perform corrective action via adjustments, component replacement, correction factors, etc.
• Identify and correct measurement errors, as applicable.
• Prepare calibration reports and certificates.
• Recommend IM & TE for use in measurement applications.
• Adapt existing calibration equipment, standards and techniques to accomplish unique measurements tasks for which they are not principally used.
• Train subordinates in calibration concepts and procedures.
• Perform lab housekeeping.
• Maintain laboratory recognition/accreditation.
• Provide technical advice to the other departments of the organization.
• Calibrate and repair IM & TE for liquid-flow measurement in a laboratory setting.
• Operate flow benches, pumps, reservoirs, reference/master flowmeters, valves, piping, pressure and temperature instrumentation, and associated data-acquisition equipment.
• Set up and operate liquid-flow calibration systems using appropriate hoses, tubing, fittings, adapters, seals, valves, and flow-control components.
• Perform zero checks, leak checks, stabilization, repeatability testing, and multiple flow-rate test points.
• Read and interpret technical manuals, manufacturer specifications, calibration procedures, reports, and work instructions to prioritize daily workflow and select appropriate flow test methods and ranges.
• Compare measurement uncertainties of a device to scope of accreditation.
• Author or revise calibration methods.
• Safely isolate, depressurize, drain, connect, and disconnect liquid-flow equipment and test systems in accordance with applicable procedures.
• Troubleshoot abnormal results to determine whether the cause is the device under test, reference standard, flow bench, pump, test connections, restrictions, leakage, or another part of the measurement system.
• Evaluate factors that affect flow measurement, including temperature, pressure, density, viscosity, entrained air, flow profile, piping configuration, pulsation, leakage, restriction, and stabilization time.
• Apply and convert common flow units, including GPM, LPM, mL/min, and other units required by customer specifications or procedures.
• Work with common liquid-flow devices such as turbine, positive-displacement, variable-area/rotameter, electromagnetic, ultrasonic, Coriolis, and other applicable flowmeters within laboratory capability.

• Minimum two years of experience in measurement and calibration; liquid-flow measurement experience is preferred.
• Civilian or military training with a working knowledge or demonstrated capacity to comprehend metrology…
