Venturi Omega is a hydro-pneumatic-device made up of two principal elements and aggregate. The aggregate may be a single element or a composed whole of many items. The two principal elements are 1 the membrane and a closing element or flow-stopper: 2 the ball, sphere or stopper. Some of the performances of the device are the following: The self-closing of the device The displacement of the ball and or the membrane which allows further actions. The displacement is originated by changes in the pressures relationship between the pressures on both sides of the membrane, the inner- and outer-side The increasing closing-force whit bigger softness of the ball The easy opening of the device and the easy handling of the flow-control, flow-monitoring and flow-measure, particularly pressure- and differential-pressure-measures. The Venturi Omega is a versatile elastic-dynamic-device. Till jet we have developed among others the following useful devices: A safety-valve whit all the working elements or machinery lying in the outer side of the membrane thus not contaminating the fluid and not being corroded and wearing away by the flow. An airplane-speedometer A barometer or atmospheric-pressure-monitoring-device A pneumatic "no hands" tap A top-level-control-device Several pressure- and differential-pressure-measure- and monitoring-devices The Venturi Omega balloons.
