Introduction to Vortex Flow Meter Vortex flow meter is a volumetric flow meter developed and produced based on the Karman vortex principle to measure the volumetric flow rate, standard condition volumetric flow rate, or mass flow rate of gases, vapors, or liquids. Mainly used for flow measurement of industrial pipeline media fluids, such as gases, liquids, steam, and other media. Its characteristics are small pressure loss, large range, high accuracy, and almost unaffected by parameters such as fluid density, pressure, temperature, viscosity, etc. when measuring volumetric flow rate under working conditions. No movable mechanical parts, therefore high reliability and low maintenance. The instrument parameters can be stable for a long time. The vortex flowmeter adopts a piezoelectric stress sensor with high reliability and can operate within a temperature range of -20 ℃ to+250 ℃. It has both analog standard signals and digital pulse signal outputs, making it easy to use in conjunction with digital systems such as computers. It is a relatively advanced and ideal measuring instrument. 2. How to install ultrasonic flowmeter
The key to installing ultrasonic flowmeter lies in the accurate positioning of the sensor and the accurate setting of system parameters, which directly determine the measurement accuracy.
.1. Preparation before Installation 1 On site investigation • Pipeline conditions: confirm the pipe material (steel, cast iron, PVC, etc.), diameter range (usually DN15-DN6000mm), wall thickness (to meet the requirements of sensor installation) • Fluid properties: clarify the medium type (clean water, sewage, alcohol, etc.), temperat
