Abstract: One or more techniques and/or systems are disclosed for accurately determining the volume of liquid in a container, such as after or prior to a fluid transfer into/from the container. The volume of liquid flowing through a flow meter can be measured at multiple data intervals by a flow meter. Further, the height of a liquid inside the container can be measured by a liquid level sensor at the multiple data intervals. A register can receive data indicative of the respective measurements, and the volume of liquid in the container can be determined based on the relationship between data indicative of the measurement of the volume of liquid flowing through a flow meter at the multiple data intervals and the measurement of the height of a liquid inside the container at the multiple data intervals.

Abstract: An improved fluid transfer accuracy, information collection, and overall management. A system may utilize a pump to transfer fluid from a source to a target vessel, a meter for measuring an amount of fluid transferred, a density meter to detect actual fluid density, and a control unit to determine actual fluid transfer amount based on density. As an example, a fluid flow meter can be coupled with a flow conduit to determine fluid volume, along with the density meter to detect real-time density of transferred fluid. During a fluid transfer event, such as aircraft refueling, LPG fueling, or other refined fuels or valuable liquids, fluid volume can be converted to fluid weight in real-time based on actual density. The real-time fluid weight can be used to determine if a target fluid weight has been reached, and fluid flow can be shut off at the appropriate time.

Abstract: One or more techniques and/or systems are disclosed for providing for improved liquid fuel delivery, by helping to mitigate damage to pumps when operated in an undesired condition. A sensor detects the presence of a liquid fuel at the inlet to the pump during pump operation, and sends the signal to a controller. Based on the detection signal from the sensor, the controller can determine whether a desired amount of liquid is present at the inlet to the pump. If a desired amount of liquid is not identified at the inlet to the pump, the controller may interrupt the power provided by a power supply, which is supplying power to operate the pump, thereby interrupting operation of the pump.

Abstract: One or more techniques and/or systems are disclosed for providing for improved fluid transfer information collection and management. Such a system may utilize scannable codes to collect fluid transfer information, mitigating the use of printable tickets, manual collection, or wireless connection and transmission to remote external devices while improving security. As an example, a fluid flow meter can be coupled with a register that collects flow information from the meter and other collected information associated with fluid transfer. Upon completion of a fluid transfer event, such as aircraft refueling, LPG fueling, or other refined fuels or valuable liquids, data associated with the transfer event, such as amount, type, conditions, operator, time, etc., can be converted into an encryptable, scannable code, such as a QR code. The scannable code can be displayed on a display screen, and captured by a portable device, and stored.

Abstract: A flow meter with a metallic case and bearing plates but with a blocking rotor and displacement rotors that are polymeric. The rotors may be sized for a reduced clearance between the rotors and surfaces of the case, bearing plates and blocking rotor. Using closer clearances between the rotors and the case bearing plates reduces leakage and provides for a more accurate measurement of the fluid through the flow meter.

Abstract: A rotary positive displacement flowmeter of the type utilizing two displacement rotors and a blocking rotor with the blocking rotor having a single recess and the displacement rotor cylinders being of substantially similar size as the blocking rotor, resulting in a uniform flowpath through the flowmeter with alignment of the rotor axes in a 180 degree plane.
