The newly formed company DH-Budenberg Group has since expanded the calibration equipment produced, to a wide range of primary standard & premium industrial pressure calibration equipment, which now includes: automated primary pressure standards, manual primary standards, differential primary standards, automatic pressure controllers, hydraulic ...
Original Cameron Iron Works Building. On the National Register of Historic Places Park Towers South, which was the former headquarters of Cameron. Cameron International Corporation (formerly Cooper Cameron Corporation (CCC) and Cooper Oil Tool, Cameron Iron Works) though now operating under Schlumberger, is a global provider of pressure control, production, processing, and flow control systems ...
Gas expansion pycnometer is also known as constant volume gas pycnometer. The simplest type of gas pycnometer (due to its relative lack of moving parts) consists of two chambers, one (with a removable gas-tight lid) to hold the sample and a second chamber of fixed, known (via calibration) internal volume – referred to as the reference volume or added volume.
The Pressure Equipment Directive (PED) 2014/68/EU (formerly 97/23/EC) [1] of the EU sets out the standards for the design and fabrication of pressure equipment ("pressure equipment" means steam boilers, pressure vessels, piping, safety valves and other components and assemblies subject to pressure loading) generally over one liter in volume and having a maximum pressure more than 0.5 bar gauge.
The formal definition of calibration by the International Bureau of Weights and Measures (BIPM) is the following: "Operation that, under specified conditions, in a first step, establishes a relation between the quantity values with measurement uncertainties provided by measurement standards and corresponding indications with associated measurement uncertainties (of the calibrated instrument or ...
In the petrochemical industry pressure is controlled by maintaining a constant pressure in the upper gas space of a vessel. [1] [9] [4] A pressure controller (PIC) adjusts the setting on a pressure control valve (PCV) that feeds gas forward to the next stage of the process. A rising pressure in the vessel results in the PCV opening to feed more ...
