  • Patent number: 12025593
    Abstract: Described herein are a selectable flow restriction device and a fluidic network for chromatographic sample dilution during injection. A selectable flow restriction device is used in combination with a splitter to define an adjustable splitter for separating a high-pressure solvent flow into two separate solvent flows having the same solvent composition. The first solvent flow passes to a sample manager where a sample is injected as a discrete fluidic plug at an injection valve into a flow comprising at least one solvent. The second solvent flow is merged downstream from the location of injection with the first solvent carrying the sample fluidic plug. The second solvent flow dilutes the sample plug during the mixture of the two solvent flows.

  • Patent number: 12007040
    Abstract: An overfill-prevention valve system includes a testing mechanism, operable by a user from the inlet end of the drop tube, which can be used to verify proper valve function without actually filling the storage tank. The testing mechanism allows the user to actuate the valve manually using a test probe, such as by elevating a float to simulate a full storage tank. The testing mechanism may be located upstream of the valve to facilitate the testing operation without interfering with the valve body. The mechanism may further provide non-contact functionality, such as with magnetic actuators on either side of the drop tube wall, to eliminate a potential test mechanism leak points. The test probe used to actuate the test mechanism may be shaped to define a desired rotational position at the test location within the drop tube, ensuring proper rotational alignment of the magnetic actuators.

    Abstract: A monitoring system that monitors a steam-using facility includes a temperature sensor that is a trap temperature sensor configured to detect a temperature of a steam trap provided in a steam discharge unit and/or a steam temperature sensor configured to detect a temperature of steam flowing into the steam trap and a pressure sensor configured to detect a pressure of steam flowing into the steam trap. The monitoring system determines that there is an occurrence of an abnormality or a sign of the abnormality in the steam trap when (i) a temperature detection value obtained by the temperature sensor and/or statistical temperature data obtained by performing statistical processing on the temperature detection value deviates from a predetermined criterion thereof and (ii) a pressure detection value obtained by the pressure sensor and/or statistical pressure data obtained by performing statistical processing on the pressure detection value deviates from a predetermined criterion thereof.

  • Patent number: 11292710
    Abstract: A fluid management system includes a fluid management controller and a fluid dispenser. The controller authorizes control of the one or more fluid management components over a wireless interface. A dispensing meter can be activated by an authentication device. The fluid meter includes a cartridge valve with a valve cartridge and a valve stem. The cartridge valve guides the valve stem and provides the only sealing surface for the dynamic seals and control seal disposed on the valve stem. The handheld meter dispenses through a nozzle, which includes an overmolded stem tip that generates a laminar fluid flow as the fluid exits the nozzle. The handheld fluid meter includes circuitry configured to invert the orientation of a visual output provided by a display of the handheld fluid meter to facilitate installation of the handheld fluid meter for use in an oil bar application.

  • Patent number: 11261887
    Abstract: The present disclosure relates to the field of fluid process systems and discloses a manifold system for fluid delivery. The system comprises a first set of Solenoid Operated Valves (SOVs), a second set of SOVs, a plurality of isolating valves, at least one first shuttle valve, and at least one redundant shuttle valve. Each set of SOVs includes at least two SOVs arranged in parallel. The SOVs together form a series-parallel redundancy. Each isolating valve is coupled to an SOV and facilitates hot swapping of that SOV. The redundant shuttle valves provide redundancy to the first shuttle valve and facilitate the flow of a fluid from each of the first set of SOVs to each of the second set of SOVs, thereby promoting system safety and availability.
