Incorrect flow measurement can lead to product quality issues, safety hazards, and significant financial losses in industrial processes.
Flow meters are used to measure and monitor fluid movement in pipes, essential for process control, billing, research, and safety applications across various industries.
Flow Meter Industrial Applications
Let me share my experience with flow meter applications across different industries.
What is the Most Commonly Used Flow Meter?
Selecting the wrong flow meter type can result in wasted investment and unreliable measurements.
Magnetic flow meters are the most commonly used type, particularly in water and wastewater industries, due to their reliability, accuracy, and lack of moving parts.
