Perform routine inspections, calibrations, and functional checks on a comprehensive range of instrumentation: Flow Instruments: Ultrasonic (transit-time, doppler), magnetic, Coriolis, vortex, variable area, thermal mass, turbine, and DP-based flowmeters with primary flow elements (orifice plates, venturis, pitot tubes). Test and troubleshoot a variety of control valves (rotary, butterfly, globe, gate, ball) and associated components, including solenoids, limit switches, position transmitters, I/P converters, positioners, volume tanks, and valve actuators (pneumatic, hydraulic, electric).
