Patent number: 8579503Abstract: A moisture flow meter is provided in the air at negative pressures in the drying of transformers by means of a vacuum process for water extraction, causing a differential of pressure through a device of orifice plate and the continuous measurement of the dewpoint. The meter includes a pipeline, a continuous dewpoint meter able to support negative pressure, as well as the use of a orifice plate and two vacuum meters (vacuum meters) capable of measuring the pressure of condensable steam as well as a orifice which, allow a pressure drop. The signals on both sides of the orifice plate and the one from the dewpoint temperature are sent to a data acquisition card, which allows to measure, with the help of an algorithm, the amount of water in weight that flows per time unit.Type: GrantFiled: September 7, 2011Date of Patent: November 12, 2013Assignee: Prolec Ge Internacional, S. de R.L. de C.V.Inventors: David Diguero Hernández, Manuel Antonio Cano Urrego
