  • Patent number: 11988543
    Abstract: An abnormality detection method is performed in a gas supply system including a flow rate control device having a restriction part, a control valve, a flow rate control pressure sensor for measuring upstream pressure, and a control circuit. The inflow pressure sensor measures the supply pressure. An upstream on/off valve is provided upstream of the inflow pressure sensor. The method includes closing the upstream on/off valve when the gas flows at a controlled flow rate at the downstream of the restriction part by controlling an opening degree of the control valve based on the output of the flow rate control pressure sensor; measuring a drop in supply pressure on the upstream side of the control valve after closing the upstream on/off valve while keeping the control valve open; and detecting the presence or absence of abnormality in the flow rate control device based on the measured supply pressure drop.

The controller is configured to receive a flow rate measurement from the flow rate sensor, adjust a control deadband based on an actuator command history, and determine a compensated position setpoint using the flow rate measurement, the adjusted control deadband, and a proportional variable deadband control technique. The controller is further configured to operate the motor to drive the drive device to the compensated actuator position setpoint.

  • Patent number: 11041749
    Abstract: Mass flow controllers and methods for controlling mass flow controllers are disclosed. One method includes providing a process gas through a flow sensor of the mass flow controller, obtaining a gas-adjusted sensitivity coefficient for the flow sensor, and obtaining gas-adjusted nonlinearity data for the flow sensor. The method also includes producing gas-adjusted characterization data for the flow sensor using the gas-adjusted sensitivity coefficient and the gas-adjusted nonlinearity data. A flow value from the gas-adjusted characterization data is obtained using a flow sensor signal from the flow sensor, and the flow value is used along with a setpoint signal to control a valve of the mass flow controller.
