DIFFERENTIAL PRESSURE DECAY AIR DECAY DIFFERENTIAL AIR DECAY A single pressure sensor is used in an air decay test to measure the test pressure and pressure drop from a leak. The sensor must be sized for the test pressure; therefore, the sensor’s range must be greater than or equal to the test pressure. WebThe pressure recovery is limited for an orifice plate and the permanent pressure loss depends primarily on the area ratio. For an area ratio of 0.5 the head loss is about 70 - 75% of the orifice differential.. The orifice meter is recommended for clean and dirty liquids and some slurry services. how is disney grooming children
