Abstract:

Flow measurement is a frequent and critical task in petrochemical production. A wide variety of flow measuring instruments are available, each offering distinct features and suitability for specific operating conditions. This paper introduces six commonly used flow instruments in petrochemical units, including differential pressure flow meters, rotameters, electromagnetic flow meters, vortex flow meters, mass flow meters, and ultrasonic flow meters. For each type, the measurement principles, typical composition, key characteristics, and applicable selection criteria are discussed, offering practical guidance for engineering designers in the type selection of flow meters.

Key words: measurement accuracy, turndown ratio;instrument
