[0001] The present application relates to the field of flow sensing and control devices, in particular to a flow sensing and control device. BACKGROUND

[0002] Flow sensing and control devices are a class of equipment systems for monitoring and measuring fluid flow, and adjusting and controlling the flow according to preset conditions or real-time data, which are widely used in industrial production, water conservancy engineering, heating ventilation, environmental monitoring and other fields. The core function is to realize accurate perception and dynamic management of fluid flow state.

[0003] The existing flow sensing and control device is the core component of the conveying system, which realizes accurate monitoring and control of liquid or fixed flow. In food and beverage production, accurate flow control is crucial for the realization of formula proportioning. When dispensing alcohol-containing syrup beverages, if the flow sensing device measures turbulently when the medium is switched, the mixing ratio of syrup and alcohol solution will be inaccurate, which will seriously affect the product quality.

[0004] The existing flow control device may need to switch different properties of medium during production, such as switching from high-viscosity syrup to low-viscosity alcohol solution. During switching, the flow sensing device is prone to measurement disorder, and the flow of high-viscosity liquid will adhere to the inner wall of the pipeline during switching, resulting in the mixing of high-viscosity liquid flow during switching, which will result in inaccurate mixing ratio of flow, seriously affecting the product quality.
