  • Chemical Processing Flow eHandbook: Monitoring Flow

    The purpose of installing a flowmeter system is to accurately measure flow in a reliable manner. Issues related to physical properties, process parameters, electronic features and interconnections are often given much consideration. Relatively little emphasis, however, is given as to how well the flowmeter will perform its intended purpose. Adding to the confusion are the differences in how performance is expressed and the incomplete nature of the available information. Nevertheless, the quality of flow measurement should be a concern. This Chemical Processing eHandbook takes a look at technologies and solutions affecting flow including: * Coriolis meters - steps you can take optimize performance when faced with entrained gas * Magmeters -- why you should consider using them * How to achieve effective flow control with centrifugal pumps

  • Technology expands flowmeter capabilities, reduces costs

    Capacitance-type magnetic flowmeters have traditionally offered the advantage of having non-wetted electrodes and the ability to measure low conductivity fluids. However, they suffered from a sensitivity to flow noise and zero instability. Innovative technology overcomes these limitations and drives magnetic flowmeters into new areas of application, while reducing installed costs.
