Abstract: An optical device configured to pass an input light signal through a medium under test, for example, a fluid, and to retrieve an output light signal. A comparison of the output light signal to the input light signal is indicative of the medium and can be used to determine if another unknown medium is the same. Another optical device passes an input signal through a known medium and an unknown medium and corresponding output light signals are received. A comparison of the output light signal corresponding to the unknown medium with the output light signal of the known medium can be used to characterize the unknown medium as against other mediums.

The spring is positioned between the holder and the base, the spring being positioned to exert a repelling force between the holder and the base to secure the holder to the base.

Abstract: A method and system for controlling a transfer of liquid from or to a transport vehicle uses a memory module on the vehicle to keep track of vehicle parameters. When a transfer request, having a plurality of transfer parameters, is received, transport vehicle parameters representative of a current condition of the transport vehicle are retrieved. The transfer parameters are compared to the transport vehicle parameters. The transfer proceeds as a result of determining that each comparison of a transfer parameter to a transport vehicle parameter is correct.

Abstract: A fluid detection flange for a product transfer verification system includes a coupling frame having an opening defining a fluid path configured to be fluidly coupled with a fluid source. A sensor in the flange measures at least one characteristic of a fluid in the opening and the sensed characteristic is used to determine the type of fluid pending for transfer. In operation, if the pending fluid is the same type as is meant to be placed in a destination container then the transfer is allowed.

Abstract: A portable fluid monitoring controller tester system for fluid monitoring equipment includes a control panel, electrical interfaces, and associated circuitry for simulating the fluid overfill sensors and other features of a trailer. The tester is a self-contained device that meets or exceeds various safety standards applicable to operating in an explosive environment. The tester may be powered, at least partially, by the fluid monitoring controller to which it is connected or from another power source, such as a battery. The tester has intrinsically safe outputs, and is configured to simulate different types of sensor systems found in fuel tanker trailers, including 2-Wire Optical, 5-Wire Optical, and Thermistor sensors. The tester is further configured to simulate ground circuits and the truck identification module (T.I.M.) of the fuel tanker trailer. The tester includes an enclosure that is impact and temperature resilient, and provides protection against windblown dust, rain and splashing water.

Abstract: An interlock monitoring system includes a magnetic proximity sensor within a poppet valve type coupler to detect whether the poppet valve is opened or closed. An open poppet valve indicates a proper connection. The sensor consists of dedicated electronics that prevent cheating, or bypassing, by either shorting out or opening the contacts to the sensor. In addition, a ferrous metal proximity switch is used to provide a redundant confirmation of proper connection of the coupler. The ferrous magnetic proximity switch will indicate whether or not the coupler is actually in contact with an appropriate connection. Each of the magnetic proximity sensor and the ferrous magnetic proximity switch must indicate a respective proper condition in order to determine a valid interlock condition.

Abstract: A fluid overfill detection and control system for controlling the transfer of fluid into a transport vehicle having multiple fluid compartments includes a plurality of overfill sensors that are connected in series with one another and that each produces an output pulse when the fluid level in its associated compartment is below a threshold level. A diagnostic line connected to each of the overfill sensors provides a diagnostic signal indicative of the number of overfill sensors that generate an output pulse, while a module on the vehicle provides an indication of the total number of overfill sensors located in the vehicle. To prevent a hazard due to the possible bypass of a overfill sensor, the controller compares the overfill sensor count signal to the diagnostic signal and inhibits the transfer of fluid into the vehicle if the values do not match.

Abstract: A hand held portable truck safety equipment tester uses loading rack criteria to confirm proper operation of the truck but is contained in a small portable battery operated unit. This unit allows for correlation to a rack controller's test and includes direct readout via an LED screen showing the error condition. Additionally, the tester has the capability to test all types of trucks without the need for adapters to accommodate different connectors and allows for remote diagnostics. The tester automatically determines which type of sensor and what grounding system is used.
