Initially, the company used turbine flow meters However, in practical applications, it was found that the measurement error was large. After analysis, it was found that the high viscosity oil caused unstable turbine rotation, affecting the measurement accuracy. Subsequently, the company switched to mass flow meters Through temperature compensation technology, the measurement accuracy was significantly improved.

2. Case 2: Measurement of liquids containing solid particles A water treatment company used electromagnetic flow meters when treating wastewater containing solid particles.
