A fluid supply system includes: fluid lines, fluid controllers and joints, in which each of the fluid lines linearly extends in an extension direction that substantially perpendicularly intersects an alignment direction of the fluid lines, each of the fluid controllers is disposed in an aligned manner in the alignment direction with connection surfaces directed to the same direction, a diameter of the pipings is equal to or less than a surface width of the connection surfaces in the alignment direction, and diameters of the joints are equal to or greater than the surface width, and the pipings that are adjacent to each other in the alignment direction are positioned with the joints displaced from each other in the extension direction.

In a gas supply system of one embodiment, if first detection information of a high-pressure sensor exceeds a first threshold value, a gas control ECU causes a pressure adjustment range to overlap a second error range of second detection information of a mid-pressure sensor, the second error range being defined with a second threshold value as a reference point. If the first detection information is less than or equal to the first threshold value, the gas control ECU offsets the pressure adjustment range relative to the second error range defined with the second threshold value as the reference point.

Techniques for detecting a high gas pressure situation within a gas delivery system (e.g., for natural gas delivery to homes and businesses) are described. In one example, a device measures gas pressure. If a pressure over a threshold value is detected, a nearby device is messaged. The nearby device either confirms the over-pressure condition or indicates it may be more localized. If the condition is present within an area of the gas delivery system and/or within a group of devices within the gas delivery system, protective measures may be taken, such as closing valves providing gas to a number of service sites.

Techniques for using data indicating if a gas regulator supplying gas at a regulated pressure to a gas meter (e.g., the gas meter of a house or business) within a gas distribution system has one or more lock-up failure events or venting events, wherein gas is vented to the atmosphere. The data may identify the identity of gas regulators at which the lock-up failure events or venting events occurred. Based at least in part on the identified gas regulators, a number of gas regulators having at least one of lock-up failure events or venting events that are connected to a same gas supply line may be identified. If the number of gas regulators having at least one of lock-up failure events or venting events on the identified gas supply line exceeds a threshold number this may indicate the presence of debris in the gas supply. Remedial steps may be taken, and the situation may be monitored and reassessed.

A system that can eliminate engine combustion emissions in addition to raw and fugitive methane emissions associated with a gas compressor package. The system may comprise an air system for starting and instrumentation air supply; electrically operated engine pre/post-lube pump, compressor pre-lube pump, and cooler louver actuators; compressor distance piece and pressure packing recovery system; blow-down recovery system; engine crankcase vent recovery system; a methane leak detection system; and an overall remote monitoring system.
