DN25 spiral vortex flowmeter

Description :

　　This product can be used to measure the flow rate and total amount of gases. It is widely used in measurement and control systems in petroleum, chemical, metallurgical, scientific research and other fields, especially suitable for measuring natural gas, dry coal gas, compressed air, etc.

　　1、 Product features:

　　No mechanical movable parts, not easily corroded, stable and reliable, long service life, long-term operation without special maintenance.

　　The shell is available in stainless steel and aluminum alloy options.

　　Built in pressure, temperature, and flow sensors, high safety performance, compact structure, and beautiful appearance; It can directly measure fluid pressure, temperature, and flow rate, and automatically track compensation and compression factor correction in real time.

　　Adopting advanced computer processing chips, it has high integration, small size, good performance, and strong overall functionality. It adopts a circuit micro power consumption design, with low overall power consumption. It can be powered by an internal battery (3.6VDC) or an external power supply (24VDC).

　　3、 Installation:

　　Before installing the flow meter, the welding slag and other debris in the pipeline should be removed first.

　　When put into operation, the upstream and downstream valves of the flowmeter should be slowly opened to avoid sudden rapid airflow and damage to the starter;

　　When the flowmeter is running, it is not allowed to open the back cover and change the instrument parameters at will, otherwise it will affect the normal operation of the flowmeter;

　　When installing the flowmeter, it is strictly prohibited to directly weld at its inlet and outlet flanges to avoid burning out the internal parts of the flowmeter;

　　For newly installed or overhauled pipelines, they must be cleaned to remove debris before installing flow meters;

　　The flowmeter should be installed in a location that is easy to maintain, free from strong electromagnetic field interference, strong mechanical vibration, and thermal radiation effects.
