This invention concerns a volumetric meter used to measure the empty volume of a reservoir/tank (RT) in automobiles, industrial reservoirs, and others, which may be irregular in shape, undeformable and hermetic, stationary or moving, flat or on an incline. This innovative electro-pneumatic volumetric meter allows the volume of the contents of a reservoir/tank to be measured precisely.

The current invention discloses a fluid dispenser especially suitable for ophthalmic treatments and delivering of ophthalmic agents such as eye drops. The fluid dispenser incorporates a tube made from compliant materials as the key dosing component. A first point and a second point on the tube may be acted upon by folding the tube or by external elements, making the segment between the first point and the second point a squeezing section that houses a dosing chamber. The squeezing section may be pressed by an anvil or other structures, pressurizing the fluid contained in the dosing chamber so that once the tube is released on one point, the fluid in the dosing chamber is discharged. With each dosing process, a single dose of the fluid is discharged. In addition, the fluid dispenser is capable of delivering a series of doses of the fluid by repeating the dosing process.

A method of a method of controlling a volume of material dispensed by a constant pressure adhesive and sealant dispensing system controlled by a controller during shots includes automatically adjusting a proportional valve control setting for an orifice size of a controlled pressure regulator. An orifice size control pressure corresponding to the proportional valve control setting is applied to an orifice size control inlet of the controlled pressure regulator. A volume of the material dispensed during each shot is monitored and when the volume of material dispensed during each shot of a predetermined number of successive shots is outside a target range, the proportional valve control setting is automatically adjusted by the controller.

An apparatus (10) is provided for dispensing a flowable product from a collapsible container (12) comprising an air-tight cavity (14) and an opening (16). The apparatus (10) includes a reservoir (18) comprising a chamber (20) for storing flowable product, the chamber (20) comprising a product inlet (22) for receiving flowable product delivered from the air-tight cavity (14) of a connected collapsible container (12) through the opening (16) thereof, and a product outlet (24) for the flowable product. A piston (46) is positioned inside the chamber (30) and is movable to vary the volume of the chamber (30), for example between a first position defining a maximum chamber volume and a second position defining a minimum chamber volume.

Embodiments provide a fluid metering device, including: a first fluid supply port for receiving a first fluid; a first fluid dispense port for dispensing the first fluid; a second fluid supply port for receiving a second fluid; a second fluid dispense port for dispensing the second fluid; a waste discharge port for discharging a mixture of the first fluid and the second fluid; a valve assembly including a plurality of valves; a manifold connected to the metering pump, wherein the manifold includes a plurality of fluid channels, and the manifold is used for communicating between the valve assembly and each port; a first tube connected between the second valve and the third valve for accommodating the mixture or the first fluid; and a second tube connected between the third valve and the fourth valve for accommodating the second fluid.
