Transmission error of oil-water interface instrument

　　1. Measurement principle error: The measurement principle of the oil-water interface instrument is based on physical principles such as buoyancy and pressure, but due to complex environmental factors in practical applications, it often leads to certain errors.

　　2. Error caused by liquid flow: During the production process, the liquid may be in a dynamic flow state, which may affect the measurement results of the oil-water interface instrument.

　　3. Errors caused by temperature changes: Temperature changes may cause changes in the physical properties of liquids such as density and viscosity, thereby affecting the measurement accuracy of oil-water interface instruments.

　　4. Errors caused by impurities in liquids: Impurities in liquids may interfere with the measurement process of oil-water interface instruments, resulting in errors.

　　Executive standards for tuning fork level switches

　　1. Standardize product design and manufacturing: The standard specifies the requirements for the design, materials, and manufacturing process of tuning fork level switches, which is conducive to improving product quality and reliability.

　　2. Promoting product technology innovation: The formulation of standardization helps to concentrate scientific research efforts and promote the innovation and development of tuning fork level switch technology.

　　3. Convenient for users to choose and use: Unified standards make it more convenient for users to choose and use tuning fork level switches without worrying about compatibility issues with products produced by different manufacturers.

　　The execution standards of the tuning fork level switch refer to a series of regulations and standards that the equipment needs to comply with during use. The execution standards mainly include the following aspects:

　　1. International standard: The commonly used international standard is the IEC (International Electrotechnical Commission) standard, among which IEC 60947-5-2 is the execution standard for tuning fork level switches. This standard specifies the requirements for the appearance, size, and working principle of the tuning fork level switch.

　　2. National standard: Currently, there is no independent national standard for tuning fork level switches in China, but international standards and relevant national standards can be referred to, such as GB/T 14048.5 "Low voltage electrical appliances - Part 5: Control switches and electronic equipment".
