Rotork valve actuation supports offshore wind farm technology

Case Study by Rotork Valves: The Borwin Alpha platform is the first offshore installation designed to convert AC power into high voltage direct current (HVDC) for onward transmission. Built and designed by the Heerema Fabrication Group on behalf of ABB, the facility can transfer a power of 400MW at a bipolar voltage of 150kV. The converted current is carried by a 200 kilometre cable for onshore connection to the European power grid.

dP or not dP? Capillary Thermal Flow Meters vs. Differential Pressure Devices—Part 1

The most common technology in use today for measuring flow is differential pressure “dP or ΔP” (orifice plates, pitot tubes, venturis and the like). Indeed, that was the only flow measurement method I was taught in engineering school. Well, things have come a long way in the 28 years since I picked up my degree. Today coriolis, ultrasonic, vortex, thermal and magnetic flow meters have all found their niches, although dP meters are still the most common due to the large installed base.

Advantages of FOUNDATION fieldbus in Thermal Mass Flow Applications

FOUNDATION fieldbus™ is an extremely stable, all digital, two-way communications technology for plant instrumentation and the best technology for utilizing advanced diagnostics. Because of all of its advantages, FOUNDATION fieldbus is gaining worldwide acceptance. In particular, many life sciences and chemical research customers have been seeking a thermal mass flow controller with FOUNDATION fieldbus communications. Brooks Instrument recently introduced the first thermal mass flow controller with FOUNDATION fieldbus technology to allow its customers to take advantage of the full power of this communications protocol.

Considering Valve Specification & Installation

When specifying valves for a given application, it is important to first determine the intended function. This may seem a rather obvious observation, but, unfortunately, a lack of functional understanding is often where valve performance issues begin. The user, rather than fully considering the application in which the valve will operate, moves forward on a purchase, only to find later on that the valve isn’t all that well suited to meet the needs of the job it is being asked to do.
