  • Introduction to Rotameters

    Introduction to Rotameters

    The rotameter is an industrial flowmeter used to measure the flowrate of liquids and gases. The rotameter consists of a tube and float. The float response to flowrate changes is linear, and a 10-to-1 flow range or turndown is standard. In the case of OMEGA® laboratory rotameters, far greater flexability is possible through the use of correlation equations. The rotameter is popular because it has a linear scale, a relatively long measurement range, and low pressure drop. It is simple to install and maintain.

  • Chemical and Pharmaceutical Sight Glass Applications Handbook

    Chemical and Pharmaceutical Sight Glass Applications Handbook

    Improperly specified, installed or maintained, sight glasses can easily become the weakest link in a chemical or pharmaceutical processing system. They may provide less than needed observation capabilities, they may require frequent maintenance and replacement, they may be difficult to illuminate and, in worst case, they may actually fail, endangering workers and causing extensive destruction and downtime.

  • FOUNDATION for Remote Operation Management: Transforming Remote Applications

    FOUNDATION for Remote Operation Management: Transforming Remote Applications

    The Fieldbus Foundation's FOUNDATION for ROM initiative is intended to develop a unified digital infrastructure for asset management in remote applications ranging from tank farms and terminals to pipelines, offshore platforms, and even original equipment manufacturer (OEM) skids. The technology enables fieldbus connectivity to remote I/O and the leading industrial wireless protocols, including WirelessHART® and ISA 100.11a. It provides an interface to these wireless technologies and uses Electronic Device Description Language (EDDL) and function blocks to ensure interoperability with FOUNDATION for ROM devices.

  • Thermal Dispersion Mass Flow Measurement Handbook

    Thermal Dispersion Mass Flow Measurement Handbook

    Thermal mass flow technology is a method of gas flow measurement that does not require correction for changes in process temperature or pressure. Thermal mass flow technology also has a benefit of measurement at low velocities and greater turndown capabilities than those obtainable with other flow measurement devices.

  • A Standard for Users & Manufacturers of Thermal Dispersion Mass Flowmeters

    A Standard for Users & Manufacturers of Thermal Dispersion Mass Flowmeters

    This standard establishes common terminology and gives guidelines for the quality, description, principle of operation, selection, installation, and flow calibration of thermal dispersion flowmeters for the measurement of the mass flowrate, and to a lesser extent, the volumetric flowrate, of the flow of a fluid in a closed conduit.
