摘要： There is a controller connected to a plurality of probes via a transmission line. The controller provides a command signal including a probe identifier signal and a probe data signal. Each probe includes a plurality of different sensors, each providing one or more status signals on a plurality of probe data channels. Each probe also includes a comparator for comparing the probe identifier signal to a local probe address, a multiplexer responsive to the data signal for selecting one of the data channels, and a switch responsive to the comparator to provide the selected data signal to the controller when the identifier signal correlates with the local probe address.

摘要： A strip of resistive carbon is deposited on a longitudinal plastic film and a strip of conductive copper is deposited on a second film. The two film strips are glued together with the resistive and conductive strips opposing to form a sealed envelope having a longitudinal cavity. This sandwich is placed in a flexible extruded tube membrane and the whole inserted in a longitudinal slot in a frame, with a channel communicating with the slot and the exterior of the frame. Liquid in a tank compresses the envelope, causing the copper and carbon strips to contract at a point depending on the level. The change in resistance of the carbon-copper circuit with level produces a changing voltage which is processed to provide a signal indicative of the level of in the tank. Temperature sensors in the frame provide the temperature of the at various levels.

摘要： A fluid detection system includes a central monitor, an overfill probe for detecting the approach of the overfill condition of a tank of liquid, and n other probes, where n is an integer greater than or equal to 1. The probes are connected to the monitor via electronic cables. The monitor communicates with the probes by producing probe identifier signals comprising integers starting with zero up to the number n. Each probe includes a signal receiving and sending means which compares the identifier signal sent by the monitor to a preset identifier number for that probe and sends a status signal indicative of the fluid status at that probe when it receives the identifier signal that is the same as the preset number. The overfill probe is set with the identifier zero. The monitor includes a timing circuit which determines a six second probe check cycle. The monitor checks one probe every probe check cycle according to the following sequence: probe zero, probe number one, probe zero, probe number two, probe zero, probe number three, etc. until all n probes are checked. The monitor also includes an interrupt mode which may interrupt the probe check function. Whenever the monitor returns from interrupt, it first checks the zeroth probe then continues in the probe check cycle from which it was interrupted.

The probe assembly may also include a detector for detecting the state of the fluid. If the fluid has a non-liquid state then the logic circuit has a third state which indicates the non-liquid state of the fluid. The probe assembly may also include a second fluid sensor mounted beneath the float in vertical spaced relationship to the one sensor.

摘要： There is a plurality of probes electrically connected to a central controller. Each of the probes is capable of providing a hydrocarbon signal, a water signal and a dry signal upon sensing these respective environments. The controller includes an audible alarm transducer and a switch for activating circuitry providing either a first alarm mode which provides an alarm in response to a hydrocarbon signal or a second alarm mode which provides an alarm in response to a hydrocarbon signal and also a water signal. A continuous alarm tone is provided upon receiving a hydrocarbon signal while an intermittent alarm tone is provided upon receiving a water signal. A yellow label links a "water" sign and the transducer and a red label links an "oil" sign and the transducer. The yellow label encircles only a small portion of the transducer and the red label encircles the major portion of the transducer so as to provide a visual indication that the shorter, intermittent tone indicates water while the longer, continuous tone indicates hydrocarbon.

摘要： A microprocessor controlled timer is installed in a petroleum service station product dispensing system that includes a pump relay, a pump, a dispenser, and a leak detection monitor. The timer activates pump relays to pressurize a liquid product line that runs from a tank to the dispenser at predetermined intervals to compensate for thermal contraction during product line leakage testing. Prior to activating pump relays, the timer has circuitry to determines if product is currently being dispensed. If product is being dispensed, the timer waits until dispensing has halted before activating pump relays to pressurize the product line. Also prior to activating pump relays, the timer has circuitry to determine if pump operation should be inhibited and if so halts before activating pump relays. Optical isolation is used between the timer and pump relays and a dispenser switch.

摘要： A fluid detection system capable of displaying the conditions in the environs of a large number of fluid detection probes and correlating each condition with the particular probe that detected it. There are a plurality of probes, each having a comparator preset with a unique probe identifier, such as a binary number. A counter produces digital signals representative of the binary numbers. The probe comparators are responsive to the numbers outputted by the counter and are connected to the probe power circuitry. When each comparator receives the signal corresponding to its preset number, it triggers its associated probe to produce status signals. A display circuit responds to both the number output by the counter and the probe status signals to simultaneously display the probe number and an indication of probe status.
