Patent number: 7064671Abstract: Methods are disclosed for collecting sensor data in a pressure regulator system including a controller and a plurality of sensors. The controller and each of the individual sensors are activated as required to collect sensor data during a sampling period thereby reducing the amount of power consumed by the pressure regulator system. Further power conservation measures are implemented by using a battery sensor to monitor the capacity of the pressure regulator battery and placing the pressure regulator in reduced power consumption operating modes as the capacity of the battery is reduced.Type: GrantFiled: February 28, 2001Date of Patent: June 20, 2006Assignee: Fisher Controls International LLCInventors: Richard J.

Patent number: 6895351Abstract: A method and an apparatus for determining fluid flow through a pressure regulator is disclosed. The pressure regulator is disposed in a fluid flow passage and has a throttling element moveable in the flow passage. A stem is attached to the throttling element. The apparatus includes a first pressure sensor for measuring pressure upstream of the throttling element, a second pressure sensor for measuring pressure downstream of the throttling element, and a travel sensor for detecting the position of the throttling element. A processor is provided which includes a stored algorithm for determining flow rate based on the measured pressure and travel values and for calibrating the pressure regulator using a temporary flow meter disposed downstream of the throttling element. A system and method is also provided for calibrating a temperature transmitter associated with the pressure regulator.Type: GrantFiled: February 24, 2003Date of Patent: May 17, 2005Assignee: Fisher Controls International LLCInventors: Bruce F.
