    Temperature Blog: Considerations in Temperature Measurement Selection

    When it comes to measuring temperature, there are a multitude of ways to do this. Do-it-yourselfers might use simple RTD or thermocouple sensors right into a microcontroller and display to provide basic temperature readings for their grills and BBQ pits. Or they could buy a ready-made transmitter and software to send the readings to their smart phones. Todd Olin Neil Larson For industrial process manufacturers...

    Flow Blog: Sizing and Specifying Orifice Plate Flowmeters

    An Emerson whitepaper, Fundamentals of Orifice Meter Measurement , shares the history of tried-and-true differential pressure (DP) measurement across an orifice plate (orifice plate flowmeters) to measure flow rate, which dates back to the end of the 1700s. The first recorded use of an orifice device for fluid measurement was in 1797 by Giovanni B. Venturi, an Italian physicist whose work led to the development of...

    Level Blog: Guided Wave Radar for Tight Boiler Steam Drum Level Control

    Matthew Brummer Boiler steam drum level control is critical in electrical power generation. Too high a level can mean water aspirating into the steam lines and causing damage to the turbine generator blades downstream. Too low a level can cause the boiler to dry and overheat. In a Power magazine article, Controlling Boiler Level When Operating Conditions Change , Emerson’s Matthew Brummer compares different level...

    Level Blog: Measuring Sediment Buildup in Process Vessels and Tanks

    Some processes, such as oil & gas production, not only have to measure liquid levels but sometimes must measure sediment levels that can come along in the production stream and settle in vessels and tanks. This quick, 2:38 “How To” YouTube video, How Does the Rosemount Sand Switch Functionality Work? , shows how to change the settings in a Rosemount 2140 vibrating fork level detector from measuring liquids, to measuring...

    DeltaV Blog: Cybersecurity Considerations in Safety Instrumented System Architectures

    Sergio Diaz Alexandre Peixoto Safety instrumented systems (SIS), which are designed to take the process to a safe state in trip conditions, come in several architectures with the basic process control system (BPCS). The SIS and BPCS can be totally separate, interfaced or integrated, yet separate. While the debate on which approach is best has been going on for a long time, what are they cybersecurity considerations...
