WP820 Vortex Flow Meter
Summary:
The vortex flow meter is a volumetric flow meter designed and manufactured based on the Karman vortex shedding principle, used to measure the volumetric flow rate, standard-condition volumetric flow rate, or mass flow rate of gases, steam, or liquids. It is primarily employed for flow measurement in industrial pipelines carrying various media, including gases, liquids, and steam, and is widely utilized in industries such as chemical processing, food production, district heating, and power generation. Its key features include low pressure loss, a wide measurement range, high accuracy, and minimal sensitivity to fluid density, pressure, temperature, viscosity, and other operating parameters when measuring flow under actual process conditions. With no moving mechanical parts and employing a piezoelectric stress-type sensor, it offers high reliability, low maintenance requirements, and long-term stable performance. It provides both analog standard signals and digital pulse outputs, making it easily compatible with computer-based digital systems, and is thus a relatively advanced and ideal measuring instrument.
