Systems, devices, and methods are provided for measuring fluid flow across a pump used in a system for precisely and accurately metering fluid. The systems, devices, and methods can use contactless approaches to measure the properties of the fluid being pumped. The measured properties can be used to precisely and accurately determine the flow rate through the pump.

Described herein is a modular device for dispensing a lubricant. A first coupling end is attachable to a source of lubrication. A second coupling end is attachable to a lubrication receiver. A control module is arranged between the first coupling end and the second coupling end. The control module includes a flow measuring device in fluid communication between the first end coupling and the second end coupling. The control module is configured to enable dispensing of the lubricant.

A magnetic sensor assembly for rotary gas meters includes a counter module electronic volume corrector (“EVC”). In one aspect, the assembly includes a magnetic sensor probe configured to be releasably secured within an aperture of a first gas meter body. The sensor probe may alternatively be positioned within an adapter sleeve. The adapter sleeve is configured to be releasably secured within an aperture of a second gas meter body. In another aspect, the counter module EVC includes a base coupling member, and the assembly includes first and second magnetic sensor probes, the probe being configured to be releasably secured within apertures of first and second gas meter bodies, respectively. Each probe has a probe coupling member that is releasably engagable with the base coupling member.

A positive displacement fluid flow meter that may have a rotary piston that rotates inside a chamber as a fluid flows through it. The rotating piston may create fixed volume discrete parcels from the passing fluid. The piston may be buoyant relative to the fluid flowing through the meter. Buoyancy of the piston may reduce friction and noise in the meter to result in a more accurate fluid flow measuring meter.

A process for injecting an immiscible liquid stream comprising a co-catalyst for a hydrocarbon conversion into a larger liquid stream that is an ionic liquid catalyst for the hydrocarbon conversion, comprising: a. feeding the immiscible liquid stream towards one or more injection quills in an additive delivery system comprising a transfer drum; b. transferring the immiscible liquid stream from the additive delivery system to the one or more injection quills in a solvent flushing system, fluidly connected downstream from the additive delivery system, wherein the solvent flushing system injects a solvent into one or more additive addition lines in the solvent flushing system; and c. continuously injecting the immiscible liquid stream into the larger liquid stream in an additive injection and mixing system comprising the one or more injection quills.
