Operation Instructions for DN100 Spiral Vortex Flow Meter

Description :

　　This product is widely used in the measurement and control systems of petroleum, chemical, metallurgical, scientific research and other fields, especially suitable for measuring natural gas, dry coal gas, compressed air, etc.

　　1、 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).

　　2、 Characteristics:

　　1. Has higher stability and corrosion resistance;

　　2. Imported high-quality specialized bearings with long service life;

　　3. The isolation between the measuring room and the ventilation room ensures the safety of the instruments;

　　4. Intelligent instrument coefficient multi-point nonlinear correction;

　　5. Built in pressure and temperature sensors, high safety performance, compact structure, and beautiful appearance;

　　6. The instrument has explosion-proof and protective functions, with explosion-proof markings of Exd Ⅱ BT6 and Exia Ⅱ CT6, and a protection level of IP65;

　　7. The system operates with low power consumption, and a 3.2V10AH lithium battery can be used continuously for more than 3 years;

　　8. The instrument coefficient and cumulative flow value will not be lost for ten years after power failure.

　　3、 Installation:

　　1. Sensors can be installed in vertical, horizontal, or any inclined position according to the flow direction indicator;

　　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 sensor should have sufficient space for the 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. When conducting pipeline pressure testing, attention should be paid to the pressure measurement range of the pressure sensor equipped on the intelligent flowmeter to avoid damaging the pressure sensor due to overpressure.
