A wastewater sewage system is disclosed. The sewage system includes a flow control valve that controls the flow of wastewater through the sewage system such that the sewage pipes in the sewage system are substantially full.

A flow meter includes a background pattern disposed behind a drip chamber, an image sensor, and a processor. The image sensor has a field of view and is configured to view the drip chamber within the field of view. The processor is coupled to the image sensor to receive image data therefrom and captures, using the image sensor, an image of the drip chamber and at least a portion of the background pattern, examines the image, and adjusts a flow rate of fluid flowing through a fluid line in accordance with the examination of the image.

A system and method for detecting phase separation in storage tanks is provided. At least one float has a density calibrated to detect a density differential among surrounding fluids. The float is buoyant on a relatively more dense lower layer of fluid such as phase separated fuel or pure water, while remaining submerged in a relatively less dense upper layer of fluid such as a gasoline/ethanol blend. A detection device sends a signal when the float rises or falls above or below a preset acceptable level.

Method and apparatus for furnishing process machines with liquid color from a supply thereof provides a loop conduit having respective ends receiving liquid color from the supply and discharging liquid color back into the supply, pumping liquid color through the loop conduit and discharging liquid color from the loop conduit at an intermediate position into a reservoir associated with a process machine upon liquid color level in the reservoir being at a low level limit.

A system and method removes well fluids, which include gas and liquids, from a storage tank. The storage tank has a gas relief valve that opens to admit atmospheric air into the storage tank when the pressure of a gas cap decreases below a vacuum threshold pressure. Well fluids flow into the storage tank and the level of liquid is monitored. When the level reaches a first level, a pump is operated by a controller to remove liquid from the storage tank. The pressure in the gas cap is monitored while the pump is operating. The speed of the pump is adjusted to maintain the gas cap pressure above the predetermined pressure and avoid the introduction of atmospheric air into the gas cap.

A liquid transport apparatus includes: a U-shaped vessel for storing the liquid; an inverse conically shaped body which is hollow and has an opening part of an upper end and an opening part of a lower end; and a rotating disk driving motor part for rotating the inverse conically shaped body on an axis extending along a substantially vertical direction. The opening part of the lower end of the inverse conically shaped body is immersed in the liquid stored in the U-shaped vessel. In the liquid transport apparatus, an overflow opening part for keeping constant a distance between the opening part of the lower end of the inverse conically shaped body and a surface of the liquid stored in the U-shaped vessel is formed.

A flow meter includes a background pattern disposed behind a drip chamber, an image sensor, and a processor. The image sensor has a field of view and is configured to view the drip chamber within the field of view. The processor is coupled to the image sensor to receive image data therefrom and captures, using the image sensor, an image of the drip chamber and at least a portion of the background pattern, examines the image, and adjusts a flow rate of fluid flowing through a fluid line in accordance with the examination of the image.

A cold bathing water to toilet diverting apparatus includes a diverter that is configured to be fluidly couplable to a bathing water conduit. The diverter is positionable between a shut off valve and a spout each fluidly coupled to the bathing water conduit. An outlet conduit is fluidly coupled to the diverter. The diverter diverts water from the bathing water conduit and into the outlet conduit when the diverter detects water in the diverter having a temperature less than a threshold temperature. A storage tank is fluidly coupled to the outlet conduit to receive water from the diverter. An auxiliary conduit is fluidly coupled to the storage tank and is configured to be fluidly coupled to a toilet's water tank to allow the storage tank to supply water to the water tank through the auxiliary conduit.

The present invention provides a smart water flow apparatus capable of maintaining a desired level of water in a reservoir using sensor technology while having an override or shutoff feature that is programmable to address variations in water pressure or to prevent flooding due to sensor malfunction or power failure.

A flow meter includes an image sensor, a coupler, a support member and one or more processors. The coupler is adapted to couple to a drip chamber. The support member is operatively coupled to the coupler. The image sensor has a field of view and is operatively coupled to the support member. The image sensor is positioned to view the drip chamber within the field of view. The processor receives data from the image sensor and is configured to: receive a first image from the image sensor, compare the first image to a second image, and generate a difference image based upon the comparison between the first and second images.
