Description vortex flowmeter
Vortex flowmeter is based on Karman vortex principle research and production, mainly for industrial pipeline fluid flow measurement, such as gas, liquid, vapor and other media. It is characterized by small pressure loss, large measuring range and high accuracy. It is hardly affected by parameters such as fluid density, pressure, temperature, viscosity and so on. No moving mechanical parts, high reliability, low maintenance. Instrument parameters can be long-term stability. Vortex flowmeter using piezoelectric stress sensor, high reliability, in -20 ℃ ~ +250 ℃ working temperature range. There are analog standard signal, there are digital pulse signal output, easy to use with the computer and other digital systems, is a more advanced and ideal measurement instruments.
