A dispensing apparatus in which product is dispensed by moving, preferably by manually applied forces from a user, an actuation mechanism, preferably a lever, from a first position to a second position and in which a potentiometer sensor, preferably a rotary potentiometer sensor, senses the relative movement of the actuation mechanism with time and permits the amount of fluid dispensed to be accurately calculated.

A system for metering at least one substance includes at least one inlet for fluid to be metered and one inlet for displacement fluid or transfer fluid, both giving access to a reservoir having an outlet from the reservoir which in turn gives access to a circuit portion in which only the displacement or transfer fluid circulates. The pump is located in this portion of the circuit, such that it works by suction for the portion of the system up to the reservoir and by impulsion beyond its position in the system.

An automatic changeover valve switches fluid communication between a fluid outlet and either a first cylinder or a second cylinder, wherein the first and second cylinders hold one or more fluids, such as a liquified gas fuel. A detection device detects acceleration information of the automatic changeover valve. A processing unit analyzes the detected acceleration information and determines when the detected acceleration information indicates that the automatic changeover valve is switching the fluid communication of the gas fuel outlet from the first cylinder to the second cylinder. An alert to a remote computing system is generated of the changeover event.

A fluid measurement device includes a container configured to contain a volume of fluid. The container defines an inlet and an outlet. A plurality of sensors are operatively coupled to the container. The plurality of sensors are configured to detect a fluid level within the container. A processing device is operatively coupled to the plurality of sensors. The processing device is configured to process data transmitted by the plurality of sensors to determine at least one rate-based property relating to the fluid.

A system to detect static volume in the material cartridge includes a mass flow meter to measure a volume of air delivered to the material cartridge. A controller is configured to determine a volume of assembly material in the material cartridge upon determining the volume of air in the material cartridge. A method to detect static volume in the material cartridge includes measuring a volume of air delivered to a material cartridge.

A probe for a closed transfer system, the probe including a probe body and a probe tip. The probe body defines an inlet, an outlet, and a plurality of channels. The outlet is in fluid communication with the inlet via at least one of the plurality of channels. The probe tip is located at a top end of the probe body and defines a first passageway. The first passageway is in fluid communication with at least one of the plurality of channels. The probe body is configured to be slidably moveable within a coupler body between a first position where the probe tip is received within the coupler body and a second position where the probe tip extends at least partially away from the coupler body to open a fluid flow path through the coupler body.

A flow control apparatus includes a body, a door, a drip chamber holster, and a valve. The door is pivotally coupled to the body. The drip chamber holster is coupled to one of the body or the door to retain a drip chamber. The valve is disposed within the body and is configured to receive a fluid line coupled to the drip chamber when the door is in an open position. The valve is operatively coupled to the door to secure the fluid line within the valve when the door is in a closed position.
