The IFOA integral flow orifice assembly is used in conjunction with a Foxboro electronic or pneumatic differential pressure transmitter. This combination uses the differential pressure created by the orifice to measure liquid, gas, and steam flow in 1/2, 1, and 1 1/2 in (approximately 15,...
A valve assembly is shown having a valving member situated generally in the path of flow of a fluid which varies in pressure and urges the valving member in generally the same direction as the flow of the fluid; a spring is shown resiliently resisting the movement of the valving member by...
A flow rectifier assembly including a manifold with a variable orifice disposed therein. Further, the flow rectifier assembly includes one or more valves disposed in the manifold and fluidly connected to the variable orifice to provide a uni-directional flow over the variable orifice. Each of the...
Variable orifice valve assembly AC Worley 被引量: 1发表: 1985年 Variable orifice valve development and A/C system performance testing First introduced in 1995, the concept of a temperature-responsive Variable Orifice Valve to control refrigerant flow (patent no.5,479,786) has been further... ...

first measurement directs air through a hole in the flow meter, thereby shifting the kinetic energy. This shift is calculated by the second measurement. There are many different types of differential flow meters, most prominent among them: orifice plates, flow nozzles, venturi tubes, and rota...
Turbulent restrictors: such as an orifice of any shape • Constant-flow control: various valves or pumps • Pressure-sensing valves • Inherent flow control: such as shallow recess or inherent annular orifice restrictors. The first four are listed in order of increasing stiffness. These four...
For orifice, turbine, and rotary displacement flowmeter applications, the flow control valve(s) should be installed in each flowmeter assembly upstream of the exiting DB&B valve. Alternatively, a station flow control valve arrangement may be installed downstream of the outlet header to provide the sa...

A microfluidic flow-focusing droplet generator can be defined with six geometric parameters: orifice width, orifice length, water inlet width, oil inlet width, outlet channel width, and channel depth (Fig.1a). To capture the effect of geometry on droplet generation, these parameters were varied ...
