A correctly installed orifice plate should have the constriction facing the direction of the fluid. The fluid contracts locally at the throttling center, increasing the flow rate and reducing the static pressure, so a static pressure difference is generated before and after the orifice plate, and this pressure difference has a certain functional relationship with
Why can’t the flow orifice be installed upside down? Read More »

Liquid level measurement of liquid chlorine storage tanks is a key link in the chemical industry. Due to the special properties of liquid chlorine, strict requirements are placed on the safety and corrosion resistance of the measuring equipment. Lined F46 magnetic flap level gauge has become an ideal choice for liquid level measurement of liquid
1. What is Ammonia Slip? Ammonia slip refers to the phenomenon where ammonia, used as a reducing agent in industrial denitrification processes, escapes into the atmosphere without fully reacting. Denitrification technologies such as Selective Catalytic Reduction (SCR) and Selective Non-Catalytic Reduction (SNCR) are employed to reduce nitrogen oxides (NOx) emissions by converting them into nitrogen
