Description vortex flowmeter
Vortex flowmeter is based on Karman vortex principle research and production, mainly for industrial piped 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 e digital pulse asy to use with the computer and other digital systems, is a more advanced and ideal measurement instruments.

Features vortex flowmeter
1, the body temperature and pressure compensation at the same time integrated compensation function, the standard volume flow measurement of fluid or standard mass flow.2, all intelligent, digital circuit design, can automatically compensate for the measured fluid density or standard volume calculation.
3, a new digital filtering and correction of the flow measurement more accurate and reliable.
4, battery-powered without external power supply can work continuously for more than two years.
5, a new lattice LCD characters, the use of more convenient operation.
