Supply LUGB-250 vortex flowmeter

Description :

　　Supply LUGB-250 vortex flowmeter

　　This product is widely used for measuring fluids in industries such as petroleum, chemical, metallurgical, papermaking, power generation, and water conservancy. The flowmeter has no movable parts, strong reliability, high accuracy, and long service life. It can accurately measure the instantaneous flow rate and cumulative flow rate of fluids over a wide flow range.

　　1、 Characteristics:

　　1. Steam, gas, and liquid can all be measured;

　　2. Low pressure loss;

　　3. No compensation is required when measuring volumetric flow rate;

　　4. Components with simple structure and no motion wear and tear;

　　5. High precision, high reliability, no need for on-site debugging;

　　6. Easy to install and maintain;

　　7. It can transmit traffic signals over long distances, connect with computers, and achieve integrated management.

　　9. Table body material: ICr18Ni9Ti;

　　10. Pressure loss: △=1.2 × r × V2 × 10-6. In the equation: △ P - pressure loss r - measured fluid density (Kg/m3) v - average flow velocity inside the pipe (m/s)

　　11. Environmental temperature: -20 ℃~+55 ℃ (special requirements for ordering instructions)

　　12. Environmental humidity: ≤ 90% RH

　　13. Atmospheric pressure: 86-106KPa

　　14. External power supply: 3.6-224VDC

　　15. Internal power supply: 3-4.5VVDDC

　　3、 Selection:

　　1. Before selecting, the type and flow rate value of the measured medium (which can be an estimated value) should be determined first, and then the specifications of the vortex flowmeter should be selected according to the flow range corresponding to different media measured by the vortex flowmeter in the table.

　　2. The flow rate of the measured medium in the pipeline must be within the flow range of the flowmeter, otherwise it cannot be used and is located at 1/2 to 2/3 of the flow range of the flowmeter.

　　3. If the actual diameter of the pipeline is larger or smaller than the selected diameter of the flow meter, a contraction tube or expansion tube should be used to reduce the diameter to ensure the correct use of the flow meter.

　　4. Select the vortex signal output method based on the purpose of the vortex flowmeter.
