Abstract: A flow detection device comprises a fluidic input port connected to a fluidic output port via a channel and a float located within the channel. A specific weight of the float exceeds a specific weight of a fluid injected in the flow detection device. Respective locations of the fluidic input port, of the channel and of the fluidic output port on the flow detection device cause the float to rise within the channel when a sufficient flow of the fluid is injected in the flow detection device. A sensor is provided to detect a position of the float within the channel. The flow detection device may be integrated in a cooling circuit having a cooling device for an electronic device to detect an eventual lack of a flow of a cooling fluid in the cooling circuit. A status of the flow of the cooling fluid is reported to a processor.

Abstract: A flow meter for intravenous liquids comprising a vertical inlet passage (2), a parallel indicating chamber (9), a ‘U’ shaped flow-resistant liquid passage (6), and an exit chamber (11). Liquid to be dispensed enters the inlet passage (2) via inlet (5) and moves down the passage to a junction with both the ‘U’ shaped flow-resistant passage (6), and the indicator passage. From the junction, the liquid rises up the indicator passage to a height proportional to the flow rate set by an external flow meter, and also through the flow resistant passage, which has an outlet (8) that delivers the liquid to the exit chamber (11) and from there to a patient through an outlet (12). The meter may be formed by an assembly of two injection molded components, thus reducing manufacturing costs.

Abstract: Milk meter for measuring a flow rate of a milk flow, provided with an inlet, an outlet, and a liquid flow path from the inlet to the outlet. The milk meter has a measuring chamber and a float in the measuring chamber configured to float on milk. The milk meter determines the flow rate from the level of milk and the milk meter is provided with a magnetic unit for generating a magnetic field and the magnetic field varies in height direction of the measuring chamber, and the float has an electronic measuring unit for measuring the strength of the magnetic field. The measured strength of the magnetic field is a measure of the height at which the float is floating on the milk and the measured strength of the magnetic field is a measure of the flow rate of the milk flow.

Abstract: An apparatus for the measurement of liquid quantity, comprising a frame (12) with a chamber space (13) inside it, an inlet duct (8) in the top part of the frame to pass a liquid into the chamber space (13), an outlet duct (11) in the bottom part of the frame to pass the liquid out of the chamber space (13) and elements (1, 2) placed in the chamber space (13) to form a weir container, said elements comprising a wall (2) and at least one orifice (1) formed in the wall, through which orifice (1) the liquid is passed out into the outlet duct (11), and means (3) for measuring the level of the liquid in the chamber space (13). The apparatus comprises means (10) for directing the liquid entering the chamber via the inlet duct (8) into at least two sub-flows (14, 15) and for directing these sub-flows from different directions to a point near the orifice (1) in the wall so that when the sub-flows (14, 15) meet again, they substantially damp the flow.

Abstract: To measure flow rates, the cross-sectional shape of the flow path is changed by inserting a multiple position gate into the flow path and altering the position of the gate to maintain the head of liquid constant with a reduced flow cross section. The position of the multiple position gate is correlated with the depth as measured with a bubbler to provide an indication of flow rate. To purge the bubbler line, a purge tank is located near the bubbler line. At timed periods or as manually initiated the controller causes an increase in pressure in accumulator portion of the purge tank. When a predetermined pressure is reached, a purge valve in the purge tank opens, rapidly allowing a burst of air at a substantial pressure and velocity to flow through the bubbler line to remove any material adhering to the bubbler outlet port. For this purpose, the purge tank acts as an accumulator until the pressure in the tank against the effective area of the inner portion of a purge valve element overcomes the resisting force of a spring, at which time the valve element moves slightly, permitting air to flow over a larger area of the valve element. This increases the area receiving the accumulator air pressure to include an outer portion of the valve element and this increased effective pressure area of the valve increases the force rapidly to cause the valve to snap open.

Abstract: To measure flow rates, the cross-sectional shape of the flow path is changed by inserting a multiple position gate into the flow path and altering the position of the gate to maintain the head of liquid constant with a reduced flow cross section. To maintain the head at a desirable range, the depth is measured and controls the position of the gate as a feedback signal. The position of the multiple position gate is correlated with the depth to provide an indication of flow rate. For this purpose, a flow path housing is clamped to a pipe and a multiple position gate is moved by pneumatic pressure into the flow stream to change the flow cross section. The depth of the head upstream of the gate is measured and the position of the gate is measured. Flow rate is determined from these two measurements. Sampling may be performed at an increased depth caused by the gate.

Abstract: This specific density of the liquid/air mixture is measured at successive levels within the reception vessel for the liquid using a reference measurement (Io) representing the specific density of the degasified liquid within a reference measuring path. The ratio of each obtained density value measurement and the reference value is calculated for each measuring level and multiplied with the specific density of the liquid to allow an accurate measurement of the overall liquid volume or flow-rate. Preferably the reception vessel (1) has a respective measuring electrode (El..En) at each measuring level with a common counter electrode (Eo) coupled to an oscillator (4) via a constant voltage circuit (5) and a coupling capacitor (6). Each measuring electrode (El-En) is coupled via a multiplexer (7) and an active rectifier (9) to an A/D converter (10) coupled to a microprocessor (11) controlling a read-out display (12).

Abstract: A testing device for determining the amount of liquid having been doctored through the Fourdrinier fabric or wire at the wet end of a Fourdrinier-type paper machine. Included is a pick-up for insertion beneath the foil blades of the paper machine, having an opening for insertion into the stream of the liquid being doctored from the pulp. A container is connected in liquid communication with the pick-up. A weir is positioned within the container to divide the container into a collection well upstream from the weir and a discharge well downstream from the weir. The container includes a still well positioned in liquid communication with the collection well. A proximity sensor is provided, and positioned with respect to the still well to sense the level of liquid in the still well. A microprocessor controlled display is provided for receiving a signal from the proximity sensor and displaying a flow rate based on the level of the liquid in the still well. The size and shape of the weir opening, and of the pick-up opening, are adjustable to bring the flow rate through the device into a suitable range for purposes of the display.

Abstract: A sewer flow measurement method and system for determining flow conditions of a sewer line system wherein separately located monitors make and record precisely synchronized and time identifiable pressure measurements, utilizing pressure-to-signal transducers positioned on the bottom of pipes where they exit into manholes. A cassette recorder records the different pressure related signals from the monitors together with a discrete identification signal from each monitor. The outputs of the recorder are then fed to a pressure-to-flow computer which provides location identified, time synchronized, flow data for the system.
