摘要： The invention relates to a conditioning unit (3) comprising a base (20) and a buffer store (21), a medium being conducted through the base (20) and a temperature control unit (23) being arranged between the buffer store (21) and the base (20) and having a first heating surface (24) and a second heating surface (25), and a temperature spread being adjusted between the first heating surface (24) and the second heating surface (25) by means of the temperature control unit (23). The aim of the invention is to devise a conditioning unit which allows the temperature of a gaseous or liquid medium to be precisely set and maintained constant despite strong variations in through-flow or pressure of the medium. For this purpose, the conditioning unit (3) is operated in a feed-back control to maintain a predetermined desired temperature (T
soll ) of the medium, a manipulated variable (Y) for the feed-back control of the conditioning unit (3) being combined from a model part (A), which calculates the power (P
v ) required for the temperature control of the medium in the conditioning unit (3), and a feed-back control part (R), which corrects the power (P
v ) calculated by means of the model part (A), a feed-back control error (F) composed of a desired temperature (T
soll ) and an actual temperature (T
ist ) being integrated exponentially into the feed-back control part (R).

摘要： A matched venturi assembly is provided and includes a venturi component (20) configured to provide for fluid communication between an inlet (21) and an outlet (23), sensors (30) coupled to the venturi component and configured to generate readings of characteristics of fluid flows proceeding through the venturi component and a venturi controller (40), which is receptive of the readings from the sensors. The venturi controller is configured to interpret the readings and is trimmable in a test phase where fluid flows with known characteristics are flown through the venturi component and interpretations of the readings are calibrated in accordance with differences between the readings and the known characteristics.

摘要： A multivariable process fluid transmitter module includes a base having a pair of recesses. A pair of pedestals is provided with each pedestal being disposed in a respective recess and being coupled to a respective isolation diaphragm. At least one line pressure assembly is mounted proximate one of the pedestals. The at least one line pressure assembly couples a respective isolation diaphragm to a line pressure sensor. A differential pressure sensor has a sensing diaphragm fluidically coupled to the isolation diaphragms by a fill fluid. At least one additional sensor is disposed to sense a temperature of a process fluid. Circuitry is coupled to the line pressure sensor, the differential pressure sensor, and the at least one additional sensor to measure an electrical characteristic of each of the line pressure sensor, the differential pressure sensor, and the at least one additional sensor. The circuitry is configured to provide an indication of fluid flow based on the measured electrical characteristic of each of the line pressure sensor, the differential pressure sensor and the at least one additional sensor.

estim (t) and J
measurement , and in which, when J
measurement corresponds to a rise in pressure of the gas in the enclosure, J
estim (t) is calculated according to the equation: (I) and when J
measurement corresponds to a fall in the pressure of the gas in the enclosure, J
estim (t) is calculated according to the equation: (II)

摘要： A small and light-weight flowmeter realizes the compensation of a zero point drift. A mass flowmeter includes: a centrifugal force/centripetal force detection strain gauge adhered to a part acted upon by a centrifugal force or a centripetal force of fluid in a pipe line in which the fluid flows and a flow rate zero point drift compensation strain gauge adhered to a position different from that of the centrifugal force/centripetal force detection strain gauge. A pulse wave propagation time between the two points is used to compensate a zero point drift of a flow rate.
