Impulse flow meters (punch plate flow meters) are mainly used for measuring material fluids in chemical, cement, metallurgical mining, steel mills, electrolytic aluminum, grain processing, pharmaceuticals, water treatment, environmental protection, and other industries. Flow meters can continuously measure the flow rate of various materials online, with multiple output functions such as instantaneous flow rate, cumulative flow rate, proportional batching, and quantitative control.
The flowmeter is designed as a whole, eliminating waste and pollution of factory products and reducing factory maintenance. Ensuring product quality and factory efficiency. Due to its tightly dust-proof design, the flow meter can provide us with a healthy working environment. Especially for working conditions with hazardous substance detection.

After the dry bulk solid material falls freely and impacts the sensing detection plate (punch plate), the sensing detection plate undergoes mechanical displacement. Then the bulk material flow passes continuously and unobstructed. That is, due to the impact force having a certain angle with the sensing detection board, the force is decomposed into a horizontal component and a vertical component. The vertical force component is overcome by the mechanical structure of the transmitter and does not work, while the horizontal force component has a differential sensor (linear adjustable differential transmitter), and this signal is detected and processed by an integrator connected to it to obtain instantaneous flow rate and cumulative flow rate.
Due to only measuring the horizontal force component, the vertical gravity generated by the hanging material in the non collision zone has no effect on the measurement. There is no zero drift. There is no need for frequent recalibration.

　　This instrument is equipped with a powder impulse flow transmitter (primary meter); (Secondary table) Powder impulse flowmeter; The steady flow device (generally designed and manufactured by the manufacturer under the guidance of the user) consists of three parts (a flow regulator should be equipped when flow regulation is required), and the system is matched as shown in the following figure
