The Vortex Flowmeter with Temperature & Pressure Compensation is designed for accurate flow measurement of steam, compressed air, and gases where density changes significantly with operating conditions. By integrating high-precision temperature and pressure sensors, the flowmeter automatically compensates for variations in process conditions and directly outputs mass flow or standard volume flow. This makes it an ideal solution for energy management, cost allocation, and precise process control.
