Abstract: A chemical injection system includes a pump in fluid communication with a chemical reservoir and a pipeline; a motor coupled to the pump and adapted to drive the pump to transfer a chemical fluid from the reservoir to the pipeline; a motor controller electrically coupled to a power module and the motor and adapted to adjust a rotational speed of the motor; and a central controller communicably coupled to the motor controller and a remote computing device. The controller includes a translator adapted to receive a signal from the remote computing device in a first communication protocol and translate the signal from the remote computing device to a command in a second communication protocol distinct from the first communication protocol, where the command is operable to adjust the motor controller to adjust the rotational speed of the motor.

Abstract: Process measurement may be achieved by systems and techniques generating output signals based on the measured process. In certain implementations, process measurement systems and techniques may include the ability to generate a magnetic field and successively change the orientation of the magnetic field. The systems and techniques may also include the ability to sense the presence of at least a first orientation of the magnetic field with a magnetic field sensor including a conductor and at least two Wiegand-effect conductors as the magnetic field orientation is changed and to generate an electrical pulse in the conductor with each Wiegand-effect conductor when the first orientation of the magnetic field is sensed.

Abstract: In fluid flow measurement applications, apparatus and associated systems, computer program products, and methods may include a positive displacement fluid flow meter having an actuator to control fluid flow through the meter, and further having two or more rotating members with substantially parallel axes that rotate in response to the actuator and to fluid flow through the meter. In various implementations, the actuator may promote and/or retard a fluid flow being measured through the meter. In some examples, the fluid flow meter may operate as a pump to controllably increase a line pressure, controllably regulate a fluid flow rate by opposing rotation of the rotating members, substantially stop a fluid flow, and/or reverse a base fluid flow direction. In an illustrative example, the meter may operate to accurately monitor and control fluid flow (e.g., fluid pressure, velocity, and/or volume) before, during, and/or after a line break.

Abstract: An architecture to supply electrical operating power in fluid flow measurement applications, apparatus and associated systems, computer program products, and methods include a receiver tunable to various radio frequencies to capture radio frequency (RF) energy that may be used to supply regulated voltage to electronic fluid flow measurement data processing circuitry. In an example implementation, the power module searches for at least one RF signal that contains substantial energy. The received energy may be converted to a rectified waveform. The converted energy may be, for example, used to supply operating power to circuits in the fluid flow measurement circuitry, and/or it may be stored, such as in a capacitor or in a battery. Preferred embodiments may store signal strength information for one or more frequencies in at least one range of frequencies, and may tune the receiver to a frequency selected from the stored frequency information.

Abstract: To provide a fault-tolerant architecture to supply electrical operating power in fluid flow measurement applications, apparatus and associated systems, computer program products, and methods include an intelligent power module with redundant and electrically independent battery strings to supply regulated voltage to electronic fluid flow measurement data processing circuitry. In a preferred implementation, the intelligent power module transmits operating power and battery status information over a two wire interface. Circuitry may encode information about the status of individual battery strings in a DC supply voltage. The fluid meter processing circuitry operates from the DC supply voltage and decodes the battery status information. Preferred embodiments may also include a switched-mode power supply capable of extracting substantially all available stored energy capacity from each of the battery strings, each of which is electrically isolated by a unidirectional current circuit.
