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.

Abstract: A gas flow pressure pulsation dampener includes a sealed housing having an inlet port, an outlet port a center section disposed between the inlet port and the outlet port. A choke plate is rotatably disposed in the center section and has a plurality of different size openings disposed circumferentially about the plate. The plate is positioned in the center section so that the openings are placed between the inlet port and the outlet port. The size differences between the openings and the circumferential separation between adjacent openings are selected so that the plate always presents one full opening or parts of two openings between the inlet port and the outlet port. Means for rotating the choke plate are provided to select one of the choke openings to be disposed between the inlet port and the outlet port.

Abstract: A flow meter includes a first coupling configured to couple to an inlet from a flow stream at one end and to one side of a meter element at another end. A second coupling is configured to couple at one end to an outlet to the flow stream and to the other side of the meter element at another end thereof. The meter element is disposed between the first and second couplings. The meter element is configured to generate a pressure drop in flowing fluid related to a flow rate of the fluid through the meter element. The meter element has metal to metal sealing surfaces for engagement with corresponding sealing surfaces on the respective ends of the first and second couplings.
