An apparatus, method and system providing for calibration and/or control of a liquid dispensing system is disclosed. The hand-held calibration auditing tool includes a flow meter (36-37) with inlets adapted for quick connection to one or more liquid inputs to a liquid dispensing system (10). A sensor (94-95) having a data output of liquid flow information for a liquid input to the dispensing system (10) is operably connected to a controller (12) to receive the liquid flow information for the liquid input. The controller (12) provides a dilution rate and other liquid flow information for a liquid product input to a dispenser.

A gas meter with a rated maximum flow capacity of greater than 3,000 CFH (Cubic Feet per Hour)for example, between 3,500 CFH and 7,000 CFHis provided with 2-inch flange connectors. One or more undercuts are provided in the meter body to promote satisfactory performance in terms of, for example, differential pressures at the meter inlet and outlet.

A fluid flow meter is described, that includes intermeshing gears that rotate synchronously. The fluid flow meter has a nominal operating range between a maximum volumetric flow rate and a minimum volumetric flow rate. The flow meter has a flow sensor to produce a pulsed output and a controller operatively coupled to a data storage medium. The controller can receive detection signal from the flow sensor to generate input pulses and determine an input pulse frequency. The controller can determine whether the fluid flow meter is operating outside the nominal operating range and apply a correction function to input pulses to generate linearized output pulses. The controller may generate the correction function based on the input pulse frequency and a predetermined pulse frequency; or based on the time interval between input pulses and a predetermined interval between input pulses; or based on a generic calibration of the fluid flow meter.

A gas meter (100) and like metering systems that are configured for use underwater. The gas meter may embody a positive displacement rotary gas meter having a meter body with impellers that counter-rotate in response to material flow. The gas meter can also comprise an index unit having an electronics assembly to generate a value that equates rotation of impellers with a parameter of the material flow. The gas meter can further comprise a connective interface having a first part and a second part, one each disposed on the meter unit and the index unit, respectively, the first part and the second part coupling with one another to provide data to the electronics assembly, the data corresponding with operating conditions on the meter unit and rotation of the impellers. In one example, the first part and the second part are configured so that the meter unit and the index unit are operable underwater to generate the value.

In one embodiment, the present disclosure includes a solid dispenser including dispensing vanes coupled rotationally about respective parallel horizontal axes. The two dispensing vanes including a surface at a radial distance from the corresponding parallel horizontal axis with teeth arranged on and projecting from the surface. The surfaces of the dispensing vanes may be in contact between the parallel horizontal axes and are flexible in radial directions of the dispensing vanes. In one example embodiment, the dispensing vanes are configured to rotate in opposing directions about the respective parallel horizontal axes to selectively dispense ingredients from a hopper.
