摘要： An apparatus (10) is provided that includes a spatial array of at least two unsteady pressure sensors (18 - 21) placed at predetermined axial locations x1 - xN disposed axially along a pipe (14) for measuring at least one parameter of a fluid (12) flowing in the pipe (14). The pressure sensors (18 - 21) comprise a plurality of pressure sensing elements such as piezoelectric film sensors (23) for measuring unsteady pressures associated with acoustical pressures and/or vortical disturbances. The sensing elements are disposed circumferentially around the pipe and spaced a predetermined distance. The pressure signals P1(t) - PN(t) provided by the pressure sensors (18-21) are processed by a processing unit to provide an output signal indicative of a parameter of the fluid.

摘要： A fluid dispensing system for monitoring a weight of a fluid dispensed by a fluid dispenser (10, 201). A first monitoring device (50, 212) determines a first flow characteristic, for example, pressure, of the pressurized fluid flowing through the fluid dispenser; and a second monitoring device (209) determines a second flow characteristic, for example, viscosity, of the pressurized fluid flowing through the fluid dispenser (10, 201). A monitor control (216) produces an output representing a weight of the fluid dispensed by the fluid dispenser (10, 201) as a function of the first and second flow characteristics. The monitor control (216) also stores values relating to a size of an orifice through which the pressurized fluid is dispensed and a density of the pressurized fluid. The weight value is determined as a function of the orifice size and the density values. The present invention also includes a method of monitoring a weight of a fluid being dispensed by a fluid dispenser (10, 201).

摘要： A method in a pressure transmitter (144) and a pressure transmitter (144) for determining a mass flow rate of a fluid in a conduit (132) measure a differential pressure between two points (136, 138) in the fluid, where the conduit (132) has a substantially constant cross-sectional area between the two points. In one aspect, the mass flow rate is calculated by multiplying the square-root of the differential pressure by a mass flow constant.

摘要： Die erfindungsgemässe Messvorrichtung zum Messen eines mit Druckgas erzeugbaren Beschichtungspulver-Massenstroms in einer Pulverleitung, umfasst eine Steuer- und Auswerteeinheit (15), die derart ausgebildet und betreibbar ist, dass sie zwischen einem Offset-Modus und einem Be-triebsmodus wechseln kann. Die Steuer- und Auswerteeinheit (15) sorgt im Offset-Modus dafür, dass eine Einstelleinrichtung (16) die Pulverleitung (9, 10) mit Druckgas (DRL) beaufschlagt und den Beschichtungspulverfluss in der Pulverleitung (9, 10) unterbindet, und dass sodann ein Drucksensor (2) den Druck in der Pulverleitung (9, 10) erfasst. Die Steuer- und Auswerteeinheit (15) interpretiert den erfassten Druck als Offset-Druckwert (poff). Die Steuer- und Auswerteeinheit (15) sorgt im Betriebsmodus dafür, dass die Einstelleinrichtung (16) den Beschichtungspulverfluss in der Pulverleitung (9, 10) freigibt, und ermittelt sodann anhand des vom Drucksensor (2) in der Pulverleitung (9, 10) erfassten Drucks (p), des Offset-Druckwerts (poff) und eines Korrekturwerts (k) den durch die Pulverleitung (9, 10) strömenden Beschichtungspulver-Massenstrom (ṁ).
