Product Introduction
Vortex flow meter is a non-contact measuring instrument, which is mainly used for flow measurement of industrial pipeline medium fluid, such as gas, liquid, steam,air and other media.
The instrument uses piezoelectric stress sensor to detect and output pulse signal. By using it together with display totalizer, the total volume flow index can be obtained. Because of its good medium adaptability, high pressure resistance and wear resistance, it is widely used in the measurement control process of petroleum, chemical, metallurgy, electric power and other industries.
Product Features
Simple and firm structure, no movable parts, high reliability, and very reliable long-term operation. It is easy to install and maintain.
The detection sensor does not directly contact the measured medium, with stable performance and long service life.
The output is a pulse signal proportional to the flow, without zero drift and with high accuracy.
The measuring range is wide and the range ratio can reach 1:10.
The pressure loss is small, the operating cost is low, and it is more energy-saving.
4-20mA, pulse with HART; Optional pulse with RS485

Production Line
2. The anti vibration performance is particularly good. Through a lot of waveform analysis and spectrum analysis on the vortex flow meter for a long time. We have designed the excellent probe shape, wall thickness, height, probe rod diameter and the matching piezoelectric crystal are processed with advanced CNC lathe to ensure the coaxiality, smoothness and other technical parameters. Cooperate with special process treatment. So as to largely overcome the common problem that the inherent self oscillation frequency of vortex flow meter affects the signal. This is our technology advantages in manufacturing vortex air flow meter . Make the vortex flowmeter manufactured by our company has excellent anti vibration capability.
3.Wide application range, steam, air flow and gas flow ,lpg flow can be measured.
