Fluid control device with zero output function for negative flow rates
The granted patent (Publication Number: US11953924B2) discloses a fluid control device that includes a fluid control valve, an upstream pressure sensor, and a downstream pressure sensor on a flow path. The device features an actual flow rate calculation unit that computes the flow rate based on the pressures measured by the sensors. Additionally, a flow rate output unit is included to output the calculated flow rate. Notably, the flow rate output unit incorporates a negative burst cutting function that outputs a zero value when the fluid control valve is open and the calculated flow rate is negative, ensuring accurate flow rate monitoring.
Furthermore, the patent details the functionality of the negative burst cutting function, specifying that it ceases after a predetermined time has elapsed since the fluid control valve was opened. The set time for this function is adjustable, allowing for customization based on specific requirements. Additionally, the patent mentions that the decision to activate the negative burst cutting function on the flow rate output unit is selectable, providing flexibility in operation. The patent also includes a storage medium storing a program for the fluid control device and outlines a fluid control method utilizing the device, emphasizing the steps involved in calculating and outputting the flow rate while implementing the negative burst cutting function when necessary.
