LIQUID FLOW RATE AUTOMATION & UNCERTAINTY – STAYING DRY

Richard Fertell
Abstract:
Real-life example of laboratory automation of data collection, device calibration, measurement uncertainty calculations & certificates for Liquid Mass Flow and Volumetric Flow Rate. Wet suits are not required to evaluate and compare coriolis mass flow meters and turbine volumetric flow meters in re-circulating systems and weigh standards. The effects of time, temperature, density, viscosity, air-buoyancy, flow stability, EMI and others can be startling; who knew? An off-the-shelf liquid recirculating system with data collection is evaluated with transfer standards for liquid flow rate and temperature. The flow system with turbine volumetric flow meters is compared with coriolis mass flow meter transfer standards. Various measurement agreements and errors are revealed for flow rate, temperature & density. Automation saves time, decreases measurement uncertainty and makes some flow rate analysis practical.
