A process pressure fluid transmitter is coupled to a differential pressure producer and measures a differential pressure across the producer. A statistical parameter is calculated upon successive differential pressure indications, and the calculated parameter is used to indicate wet gas flow. The indication can be generated locally at the process pressure transmitter, …

Pressure support ventilation (PSV) is a mode of positive pressure mechanical ventilation in which the patient triggers every breath. PSV is deliverable with invasive (through an endotracheal tube) or non-invasive (via full face or nasal mask) mechanical ventilation. This ventilatory mode is the most comfortable for patients and is a useful ventilator setting for …

Differential pressure is measured using a variety of gauges including: *Magnehelic® Gauges, *Photohelic® Gauges, or digital electronic pressure drop indicators. These gauges typically measure differential pressure in units of inches of water gauge ("w.g.) though other scales such as mm of water, mm of mercury, or pascals are used.

Flow transmitters use several meter technologies, including differential pressure (DP). The basic operating principle of DP meters is that a pressure drop across a meter is proportional to the square of the flow rate. Examples of DP meters include orifice plates, cone devices, Pitot tubes, Venturi tubes, and flow nozzles.
