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

Types of Errors Reference Error: Definition: Reference error is the ratio of absolute error to the measurement range, expressed as a percentage. Formula: Reference Error (%) = (Absolute Error / Measurement Range) × 100 Absolute Error: Definition: The difference between the measured result and the true value. Formula: Absolute Error = Measured Value – True

Process instruments are devices used in the field of industrial automation to measure and control process variables (such as temperature, pressure, liquid level, flow, etc.). In process control systems, sensors or transmitters communicate with the control system through electrical signals, and this communication method is usually divided into two-wire, three-wire and four-wire systems. These three
