Sonic nozzle based molblocs for gas flow

Since the mass flow through molbloc-S is proportional to the upstream absolute pressure, the flow range for this sonic nozzle calibration device in an application may be limited by the BPR limit. To maximize the range of a molbloc-S element, a vacuum pump can be connected downstream to reduce the downstream pressure while flowing.Get price

Switchgear | Project Gutenberg Self-Publishing - eBooks

A switchgear may be a simple open-air isolator switch or it may be insulated by some other substance. An effective although more costly form of switchgear is the gas-insulated switchgear (GIS), where the conductors and contacts are insulated by pressurized sulfur hexafluoride gas (SF 6). Other common types are oil or vacuum insulated switchgear.Get price
