DN250 Intelligent Spiral Vortex Flow Meter

Description :

　　This product is widely used in industries such as kerosene, chemical industry, power sector, metallurgical manufacturing, industrial boilers, etc. It is a gas flow detection instrument for measuring the volume flow rate and total amount of low viscosity gases in natural gas and gas pressure regulating station pipelines, as well as gas thermal measurement.

　　1、 Characteristics:

　　No mechanical movable parts, corrosion-resistant, stable and reliable, long service life, long-term operation without special maintenance;

　　Using 16 bit computer chips, high integration, small size, good performance, and strong overall functionality;

　　The intelligent flowmeter integrates a flow probe, microprocessor, pressure, and temperature sensors, and adopts a built-in combination to make the structure more compact. It can directly measure the flow rate, pressure, and temperature of the fluid, and automatically track compensation and compression factor correction in real time;

　　Cooperate with our company's FM type data collector to enable remote data transmission via the internet or network;

　　Pressure and temperature signals are input to the transmitter, with strong interchangeability;

　　The whole machine has low power consumption and can be powered by internal batteries or external power sources.

　　2、 Technical parameters:

　　1. The flow range is the flow range verified at the time of product delivery (at room temperature and atmospheric pressure, the medium is air 1.205Kg/m3); As the pressure increases, the flow range also expands.

　　2. Standard state conditions; P=101.325kPa，T=293.15K。

　　3. Usage conditions: Environmental temperature: -30~+60 ℃, medium temperature: -20~+80 ℃, relative temperature: 5%~95%, atmospheric pressure: 86kPa~106kPa.

　　4. Electrical performance indicators

　　Working power supply: external power supply:+24VDC, internal power supply: 3.6V lithium battery, overall energy consumption: external power supply,<1W, internal power supply,<0.3MW, lithium battery can be used for more than two years.

　　Output mode: frequency signal, 4-20mA signal, RS485 communication (capable of transmitting temperature, pressure, instantaneous flow rate, and cumulative flow rate parameters).

　　3、 Installation precautions:

　　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.

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