Pressure Regulator Selection Based on Performance, Design Pipe-Line.com

<<Understanding the various types and designs of pressure regulators is
necessary for gas transmission and local distribution companies to make a cost-effective choice for each and every application. A pressure regulator controls the gas flow from a higher to a lower pressure system, while attempting to maintain a constant system pressure. Such regulators are used throughout the gas industry to control the many different pressures used to move gas from production wells to the end user. The gas industry employs two main types of regulators: pressure-reducing regulators, which control the gas flow to maintain downstream pressure, and back-pressure (relief) regulators, which control upstream pressure. Both types are used as overpressure protection devices. Pressure reducing regulators in series work as monitor regulators. Back pressure regulators are used as relief valves to prevent the lower pressure system from being over-pressured. These types of regulators are available in two designs, self-operated and pilot-operated. Knowledge of each type and design is important for proper application, performance, trouble-shooting, and overseeing maintenance and operation.>>

Liquid Flowmeters (excellent reference)

<<An overview of types and capabilities, plus guidelines on selection,
installation, and maintenance. Measuring the flow of liquids is a critical need in many industrial plants. In some operations, the ability to conduct accurate flow measurements is so important that it can make the difference between making a profit or taking a loss. In other cases, inaccurate flow measurements or failure to take measurements can cause serious (or even disastrous) results.>> Received on Fri Oct 27 13:27:00 2000
