Abstract:
A fluid level transmitter combination (200) for placement on a tank (205) having ≤ 2 tank apertures. At least one flange (207a, 207b) provides a first, second and third flange aperture (207a1, 207a2, 207a3) over the tank aperture(s) (205a, 205b). A temperature sensor (216) over the first flange aperture senses a temperature. A first pressure sensor (215a) over the second flange aperture senses a first pressure. A level transmitter (230, 230') extends through the third flange aperture for transmitting a pulse signal into the process fluid or at its surface and receiving a pulse echo or a second pressure sensor (215b) senses a second pressure. A processor (225) is coupled to the level transceiver or to an output of the second pressure sensor that implements a compensated fluid level determination algorithm (227) using the temperature, first pressure, and pulse echo or second pressure to generate a compensated fluid level measurement for the process fluid. A transmitter (235) is coupled to an output of the processor.
Abstract:
A level measurement device comprising a container and a fluid that partially fills the container, the fluid having a surface that is exposed to a second fluid of lesser density wherein the surface has two ends spaced apart, the container having a window through which one end of the surface is visible. A reference line carried by the window indicates the relative level of the fluid.

Abstract:
An apparatus for determining a density-compensated liquid level in a vessel containing a mixture of liquid and vapors comprises a temperature sensor which produces a signal that is proportional to the temperature of the mixture; and a processing apparatus that includes one or more pressure sensors that allow for a measurement of an operating pressure and a differential pressure between the mixture in the vessel and a constant reference leg. The processing apparatus further includes an integral microprocessor for calculating the respective specific gravities of the liquid and vapor portions of the mixture based on the operating pressure, and then computing the density-compensated liquid level in the vessel based on such calculations of specific gravity and the differential pressure.
Abstract:
An appliance for monitoring in sterile conditions the rate of flow of a body fluid flowing out of a catheter according to the principle of Pitot has a measurement cell (3) upon which the body fluid is applied from above through an inflow chamber (25). The measurement cell (3) has a measurement chamber (31) separated from the inflow chamber (25) by a partition (26), and a covering part (10) with two ventilation openings (28, 28a) closed by bacteria-proof filters (110, 111) by means of which the measurement chamber (4) and the inflow chamber (25) are ventilated. The measurement cell (3) further contains a Pitot tube (43) that may be connected by a connecting pipe (39) to a pressure gauge (2). The Pitot tube (43) is also sealed by a bacteria-proof filter (60) with respect to the connecting pipe (39). Wetting of the bacteria-proof filters (60, 110) by the liquid to be measured is prevented by the liquid barriers (101, 105) arranged within the central part (9) of the measurement chamber (4) or at the lower end of the Pitot tube (43).

Abstract:
The innovation concerns a level indicator for reading the level of a liquid, preferably wine, in a bag-in-box. The indicator comprises a bag (3) containing a liquid and a tube (4) connected to the bag. The level indicator bag is put between the box and the bag which holds the wine and the tube can be arranged vertically. The liquid rises in the tube in proportion to the weight of the wine in the bag and the level in the tube discloses the level of the wine in the bag.
