Abstract: An automated system for dampening pulsation of a medium, wherein the system comprises a pressure pulsation dampener, a transducer, and a control unit for instructing a motor to move the choke plate depending on signals sent from the transducer. The pressure pulsation dampener has a housing, a choke plate, a shaft, an indicator plate, a stop pin and a removable fastener for engaging at least one of the plurality of indicator openings and securing to a portion of the outlet half housing.

Abstract: A pressure pulsation dampener for use in a gas stream is disclosed herein. The dampener can include a housing with an inlet half and an outlet half having a recess, a shaft hole, and an extension with an outlet port. The inlet half can be secured to the outlet half, and can have an extension with an inlet port, forming a flow path. A choke plate can be disposed in the recess within the flow path. A shaft can be disposed through the outlet half to move the openings. The dampener can include an indicator plate with indicator openings. A fastener can engage the indicator openings and secure to the outlet half. The dampener can have a transducer, a motor connected to the shaft, a motor driver, and a controller in communication with the motor driver for comparing frequency rates to preset limits and activating the motor.
