Abstract: A fluid management controller includes a processor, a wireless interface, and a memory. The wireless interface is configured to communicate between the processor and one or more fluid management components. The processor is configured to authorize control of the one or more fluid management components over the wireless interface. The memory is encoded with instructions that, when executed by the processor, cause the processor to provide dispense authorizations to the one or more fluid management components and record fluid dispense information from the one or more fluid management components in the memory.

Abstract: A fluid management system includes an authentication device and a fluid dispensing meter, and the fluid dispensing meter includes a processor and a memory. The authentication device is configured to provide data to the processor. The processor is configured to recall information from the memory, to compare the information to the data received from the authenticator, and to control a trigger control mechanism between the activated state and the deactivated state based on the comparison.

Abstract: The lubricant level within a reservoir is difficult to monitor, leading to the reservoir being refilled more often than necessary to ensure that the reservoir always contains lubricant. A lubricant level sensing system is connected to and monitors various aspects of the pump assembly that draws lubricant from the reservoir. The pump assembly displaces a known volume of lubricant with each pump stroke. A lubricant-level estimator calculates an estimated lubricant level remaining in the reservoir based on a stroke-count value as sensed from the pump assembly and on a reference value stored in a memory. The estimated lubricant level provides the lubricant remaining and the rate of usage such that maintenance can be scheduled ahead of time to prevent the reservoir running dry.
