DN32 spiral vortex flowmeter

Description :

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

　　1、 Technical parameters:

　　Measuring fluids: natural gas and other gases

　　Caliber series: DN25-DN200

　　Accuracy level: ± 1.00/, ± 1.50%

　　Repeatability: less than one-third of the absolute value of the basic error limit

　　Working power supply: 24-28VDC (two-wire system), external 12-28VDC (three wire system), dry battery

　　Output signal: frequency pulse signal, 4-20mA, RS485 communication

　　Electrical interface: M20X1.5

　　Protection level: IP65

　　Environmental temperature: -30 ℃~+55 ℃

　　Relative humidity: 5% to 95%

　　Atmospheric pressure: 86KPa~106Kpa

　　Working conditions: Medium temperature: -20 ℃ --+70 ℃

　　Nominal pressure: 1.6, 2.5, 4.0, 6.3 MPa

　　Pipeline connection: flange connection

　　2、 Main features:

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

　　2. Implemented mechatronics integration, eliminating the need for manual monitoring in daily measurement processes;

　　3. The installation conditions for the process are not strict, and the straight pipe sections upstream and downstream of the instrument can be greatly shortened compared to orifice plates and vortex flowmeters;

　　4. The measurement accuracy of the system can meet the current trade measurement requirements (≤ 1.5%);

　　5. The flow measurement range is wide (qmax/qmin=15-20), which can effectively work in small flow areas that orifice plates and vortex flowmeters cannot access;

　　6. Small size, light weight, and convenient offline calibration;

　　7. The measurement signal can be displayed locally or transmitted remotely as needed.

　　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.
