Description :

　　DN200 Intelligent Spiral Vortex Flow Meter

　　The main technical indicators of this product have reached the advanced level of similar foreign products. Widely used in industries such as petroleum, chemical, power, metallurgy, and coal. It has the advantages of strong functionality, wide flow range, simple operation and maintenance, and easy installation and use.

　　1、 Characteristics:

　　No mechanical movable parts, stable and reliable, long service life, low long-term operation and maintenance rate;

　　Adopting advanced computer chips, high integration, small size, good performance, and strong overall functionality;

　　The intelligent flowmeter is equipped with built-in pressure and temperature sensors, which directly measure the flow rate, pressure, and temperature of the fluid, and automatically track compensation and compression factor correction in real time;

　　Adopting a novel dedicated display screen with multiple digits for intuitive and convenient reading, it can directly display the volume flow rate in the working state, the volume flow rate and total amount in the standard state, as well as parameters such as medium pressure and temperature;

　　The dual probe structure can eliminate measurement errors caused by vibrations in air ducts and pipelines;

　　The flow integrator can display locally or remotely, with a remote transmission distance of up to 100m;

　　The pressure and temperature transmitters adopt a built-in structure, making the structure more compact and safer;

　　● Low power consumption, can be powered by an internal battery or an external power source.

　　3、 Installation:

　　1. The directional signs can be installed in vertical, horizontal, or any inclined position.

　　2. When the pipeline is long or close to the vibration source, supports should be installed upstream and downstream of the flowmeter to eliminate the impact of pipeline vibration.

　　3. The installation location of the vortex flowmeter should have sufficient space for inspection and maintenance of the flowmeter, and should meet the environmental requirements of the flowmeter.

　　4. Avoid interference from strong external magnetic fields.

　　5. When installed and used outdoors, there should be a cover to avoid direct sunlight and rainwater erosion, which may affect the service life of the instrument.

　　6. During pipeline pressure testing, attention should be paid to the pressure measurement range of the pressure sensor equipped with the intelligent vortex flowmeter to avoid damage to the pressure sensor due to overpressure.

　　7. Attention should be paid to the influence of installation stress. The upstream and downstream pipelines of the flowmeter should be coaxial, otherwise shear stress will be generated. The installation location of the flowmeter should consider the thickness of the sealing gasket or install an elastic expansion joint on the downstream side.
