A flow sensor includes a fluid chamber configured to receive a fluid. A diaphragm assembly is configured to be displaced whenever the fluid within the fluid chamber is displaced. A transducer assembly is configured to monitor the displacement of the diaphragm assembly and generate a signal based, at least in part, upon the quantity of fluid displaced within the fluid chamber.

By implementing an oil monitoring in a rotary meter, the meter can check the oil level, condition and/or both level and condition and report any issues detected such as out-of-limit low oil condition, contamination, etc. The function can trigger a preventative maintenance on the rotary gas meter with a view to improving its longevity. Oil level monitoring may be signalled using sensors such as switches. Oil colour, clarity, aeration and foaming, corrosion, varnish, wear debris, or other quality monitoring may be signalled using sensors such as spectrometers. A rotary meter may be configured with one or more such sensors for (multi-)parameter monitoring and the one or more sensors positioned in respective locations such as at an oil reservoir.

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.

In one embodiment, the present disclosure includes a dispenser vane comprising a flexible outer surface and a plurality of flexible teeth arranged along the length of the outer surface. The flexible outer surface and flexible teeth are radially moveable.

Method for adjusting the volumetric flow ratio of at least two different fluids (F1, F2) with a control-device. The control-device comprises a first chamber with a chamber-volume (V.sub.C1) for the first fluid (F1) and an inlet-element and an outlet-element for the first fluid (F1) and at least one rotating or nutating element. The control-device further comprises at least one second chamber with a chamber-volume (V.sub.C2) for the second fluid (F2), wherein the second chamber has an inlet-element and an outlet-element for the second fluid (F2) and at least one rotating or nutating element. The rotating or nutating elements are coupled so as to rotate or nutate at a defined rotational or nutational frequency ratio and are driven by the fluids (F1, F2). The chamber volume ratio (V.sub.C1:V.sub.C2) and the rotational or nutational frequency ratio are selected such that the fluids (F1, F2) flowing out of the outlet-elements have a predefined volumetric flow ratio. The input resistor (R.sub.i) of the respective inlet-element and the output resistor (R.sub.o) of the respective outlet-element of the first chamber and/or the second chamber are chosen so as to satisfy the equation: (I), wherein η.sub.F is the viscosity of the respective fluid (F1, F2) and Cn designates the respective chamber.

By implementing an oil monitoring in a rotary meter, the meter can check the oil level, condition and/or both level and condition and report any issues detected such as out-of-limit low oil condition, contamination, etc. The function can trigger a preventative maintenance on the rotary gas meter with a view to improving its longevity. Oil level monitoring may be signalled using sensors such as switches. Oil colour, clarity, aeration and foaming, corrosion, varnish, wear debris, or other quality monitoring may be signalled using sensors such as spectrometers.

A volume fraction meter that includes a flow meter coupled to a flow line. The flow line includes a turned portion and the flow meter is positioned upstream from the turned portion with respect to a flow direction. The flow meter is configured to measure a volumetric flow rate of a multiphase fluid flowing in the flow direction through the flow line. The flow line includes a nozzle opening downstream the turned portion. The volume fraction meter also includes a strain gauge coupled to the flow line between the flow meter and the turned portion of the flow line. The strain gauge is configured to measure a bending strain on the flow line upon discharge of the multiphase fluid through the nozzle opening, such that the bending strain and the volumetric flow-rate provide inputs for determining a mixture density of the multiphase fluid.

A side view fluid meter counter assembly comprises a mounting bracket to mount a mechanical counter to an end of a fluid meter (e.g. gas meter) and a drive mechanism to drive a counter shaft of the mechanical counter from rotational movement of a rotationally driven member of the fluid meter. The rotationally driven member has a drive shaft extending in an end facing direction to connect to the drive mechanism and the mounting bracket mounts the mechanical counter in an orthogonal direction to the end facing direction such that a face of the mechanical counter is viewable from a side of the meter. The drive mechanism may comprise a worm drive. The drive mechanism may further comprise a pair of bevel gears. The mounting bracket further mounts the drive mechanism. Further provided is a fluid meter having a side view counter.
