摘要： For controlling energy transfer (Q) of a thermal energy exchanger of an HVAC system, a control system determines flow-dependent model parameters (M) for modelling performance of the thermal energy exchanger, using a plurality of measurement data sets, each measurement data set including for a respective measurement time a value of a measured flow of fluid (Φact), a value of a measured supply temperature (Tsup) of the fluid, and a value of the measured return temperature (Tret) of the fluid. The control system calculates an estimated energy transfer (Qest) of the thermal energy exchanger, using the flow-dependent model parameters (M), and controls (S4) the energy transfer (Q) of the thermal energy exchanger by regulating (S5) the flow of fluid (Φ) through the thermal energy exchanger, using the estimated energy transfer (Qest).

摘要： An automated meter testing system that includes a fluid inlet valve fluidly coupled both to a fluid source and an inlet on the at least one meter. The fluid source provides fluid pressure to move fluid through the at least one meter. A flow control valve is fluidly coupled to the at least one meter opposite the fluid inlet valve. A valve controller that operates the flow control valve. A controller is electrically connected to the valve controller. The controller sends at least one signal to the valve controller to incrementally open or restrict the flow control valve to increase or decrease a flow rate of the fluid through the at least one meter.

摘要： Drive techniques for a digital flowmeter are described. The drive techniques account for delays caused during digital signal processing of sensor signals that correspond to a motion of a flowtube, as well as drive signals that impart motion to the flowtube. Such delays may be caused by a variety of factors, including delays associated with analog/digital conversion of the signals and/or filtering of the signals. The techniques include open-loop techniques and closed-loop techniques, which can be used separately or together during the start-up and operation of the digital flowmeter.

摘要： A flow rate of a fluid flowing in a tubing is determined using a flow meter. The flow meter measures a value related to the flow rate. The tubing has a valve for controlling the fluid flowing through the flow meter. The method of determination of the flow rate includes closing the valve and measuring a first zero flow rate value at a first time and a second zero flow rate value at a second time, estimating an error of the value measurement based on the first and second zero flow rate values, opening the valve and measuring value of the flowing fluid, applying an error correction to the measured value of the flowing fluid, and calculating a corrected flow rate based on the corrected value of flowing fluid.

摘要： A thermal mass flow meter and a thermal mass flow control device addresses a thermal siphon error, even if they are in a compact and inexpensive structure, without using a flow path converting block. A control computing process portion is configured to correct a measurement error caused by thermal siphon by calculating a correction value based on a measurement value at time of depressurizing fluid flow path and flow rate measuring conduit to an atmospheric pressure or less, a difference between the measurement value and a measurement value at time of charging an actual fluid into the flow rate measuring conduit, kind of the actual fluid, pressure at time of charging the actual fluid, and flow ratio of the fluid flowing in the fluid flow path and the flow rate measuring conduit, storing the correction value, and correcting an actual measured output flow value by the stored correction value.

摘要： A sensor includes one or more sensor transducers coupled with a signal conditioning IC incorporating signal conditioning circuitry and memory devoted to storing end-user downloadable coefficients. In a preferred embodiment, the IC is an ASIC and the end-user downloadable coefficients are pre-selected by the end-user based on its needs, and the coefficients are pre-stored in the ASIC when the sensor is calibrated. This results in a more cost-effective and space-efficient sensor device with improved functionality over that available in the prior art.

摘要： A method for delivering a process gas to a reaction chamber of a plasma processing system using a recipe having a recipe flow rate is provided. The method includes delivering the process gas by a gas flow delivery system controlled by a mass flow controller (MFC) to an orifice. The predicted flow rate is previously computed by pressurizing a gas. The predicted flow rate further being previously computed measuring a set of upstream pressure values of the gas via at least one pressure sensor. The method also includes applying, using a programmed computing device, a calibration factor of a set of calibration factors to determine the predicted flow rate, the calibration factor being a ratio of an average of the set of upstream pressure values to an average of a set of golden upstream pressure values.
