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.

An intelligent fluid flow regulation device that includes a pressure regulator within a fluid flow passage that has an associated throttling element moveable in the flow passage. A number of sensors in communication with the fluid flow passage and the throttling element are provided that communicate information from the sensors to a processor also contained within the regulation device. A communication unit is also included within the regulation device that affords communication between one or more devices that are external to the fluid flow regulation device and the processor within the regulation device.

A reporting regulator for use in a gas transportation system includes an electrical interconnection that couples a plurality of input ports to a processor and a memory. Sensor data is received at the input ports and the data is stored into the memory. The reporting regulator is assigned a unique identification number such as a MAC address. The reporting regulator marks the received sensor data with attributes such as an identification number, a time stamp or a date stamp. After marking the data, the data is transmitted to a database location. The marked data can be reassembled in time and space by a central computer using the attributes. A processor can utilize this data to monitor, characterize and control an entire gas transportation system. System events can be pinpointed in time and space using the marked data. Further, system characterization and performance metrics can be utilized to improve system efficiency, emergency management, scheduling of preventive maintenance, and billing methods.

A storage tank monitoring system may include a stored media sensor adapted to sense a storage tank media parameter which may responsively generate a stored media signal, a blanket gas sensor adapted to sense a storage tank blanket gas parameter which may responsively generate a blanket gas signal, and a blanket gas flow sensor adapted to sense the flow of blanket gas which may responsively generate a blanket gas flow signal. The storage tank system may further include a controller unit adapted to receive at least one of the stored media signal and the blanket gas signal, and the blanket gas flow signal, and responsively generate a blanket gas leak indicator signal. As such, a blanket gas leak indicator includes at least one of a first and a second state wherein the first state is indicative of a blanket gas leak and the second state is indicative of no blanket gas leaks.

An intelligent pressure regulator for maintaining a fluid in a process at a predetermined pressure includes an electronic controller which enhances regulator performance and provides self-diagnostics and communications capabilities. The electronic controller includes a pressure sensor which provides a signal indicating the pressure of the fluid being controlled, an adjusting pressure for adjusting the position of a throttling element; and a PID controller which receives the signal indicating the pressure of the fluid being controlled and applies the adjusting pressure to the actuator in response to the signal.

A fluid control valve having a valve body, a cage, and a flexible elastomeric diaphragm with a formed convolution to fully open the cage opening. An elastomeric diaphragm regulator with a flow diverter in the fluid flow path to reduce fluid flow separation and thereby reduce the required flow recovery area before pressure throttling. A raised knife edge seat located on the cage top in a position of stagnant fluid flow to reduce the build-up of contaminants on the seat. An elastomeric diaphragm regulator with a valve actuator coupled to a guided valve stem attached to the regulator diaphragm.
