Vortex flowmeter is a volumetric flowmeter that measures the volumetric flow rate, standard volumetric flow rate, or mass flow rate of gas, steam, or liquid, based on the Karman vortex street principle. It is primarily used for flow measurement of medium fluids in industrial pipelines, such as various media including gas, liquid, and steam.

Its characteristics include low pressure loss, wide measurement range, high accuracy, and almost no influence from parameters such as fluid density, pressure, temperature, and viscosity when measuring volumetric flow under operating conditions. With no moving mechanical parts, it has high reliability and requires minimal maintenance. The instrument parameters remain stable over a long period of time. The vortex flowmeter adopts a piezoelectric stress sensor, which is highly reliable and can operate within an operating temperature range of -20℃ to +250℃. It has both analog standard signal and digital pulse signal outputs, making it easy to use with digital systems such as computers. It is a relatively advanced and ideal measuring instrument.

Product Features:

1. Small pressure loss, wide measurement range, and high accuracy;  

2. When measuring volumetric flow under operating conditions, it is almost unaffected by parameters such as fluid density, pressure, temperature, and viscosity;  

3. There are no moving mechanical parts, thus ensuring high reliability and minimal maintenance;  

4. The instrument parameters can remain stable over a long period of time. This instrument adopts a piezoelectric stress sensor, which is highly reliable and can operate within an operating temperature range of -25℃ to +320℃;  

5. Wide range of applications, capable of measuring flow rates of fluids such as steam, gas, and liquid;  

6. The user-friendly menu and interface based on dot matrix display, coupled with bright backlighting, support both Chinese and English languages, making it suitable for various customer groups;  

7. Support temperature and pressure measurement to facilitate the compensation of temperature and pressure for gaseous media;  

8. Support flow rate conversion and display function, facilitating on-site observation of current flow rate;  

9. Support split-screen display function, allowing for enlarged display of a single or two parameters (temperature, pressure, flow rate and velocity under working and standard conditions, etc.) on the screen;  

10. Simulation output function, supporting 4-20mA current simulation and frequency output simulation, facilitating on-site non-actual flow debugging;  

11. Supports 4-20mA output, pulse (equivalent) output, alarm output, and RS485 communication output;  

12. Both two-wire and three-wire systems are isolated by DCDC (DC1000V);
