Overview

Product Details

The flange vortex flowmeter is a new type of flowmeter that measures fluid flow in closed pipelines based on the Karman vortex principle. Due to its excellent medium adaptability, it can directly measure the volumetric flow rate of steam, air, gas, water, and liquid without temperature and pressure compensation. Equipped with temperature and pressure sensors, it can measure the volumetric flow rate and mass flow rate under standard conditions, making it an ideal alternative to throttling flowmeters as shown in Figure 1.

1、 Product Overview

The LUGB series flange vortex flowmeter is a new type of flowmeter developed based on the principle of liquid vibration, widely used in the measurement of fluids in industries such as petroleum, chemical, metallurgy, and papermaking. This 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 liquids over a wide flow range. It is not affected by the temperature, pressure, viscosity, and composition of the medium, and is not blocked, stuck, easy to scale, resistant to high temperature and high pressure, safe and explosion-proof, suitable for harsh environments. Integrated display and remote transmission of flow scoring, and can output pulse signals or current signals to be networked with a microcomputer.

2、 Main features

1. The structure is simple and sturdy, with no movable parts, high reliability, and very reliable for long-term operation.

2. Easy to install and very convenient to maintain.

3. The detection sensor does not directly contact the measured medium, with stable performance and long lifespan.

4. The output is a pulse signal proportional to the flow rate, with no zero drift and high accuracy.

5. The measurement range is wide, and the range ratio can reach 1:10.

6. Less pressure loss, lower operating costs, and more energy-saving significance.

7. Within a certain Reynolds number range, the output signal frequency is not affected by the physical properties and composition changes of the fluid. The instrument coefficient is only related to the shape and size of the vortex generator, and there is no need to compensate when measuring the fluid volume flow rate. After replacing the accessories, there is generally no need to recalibrate the instrument coefficient.

8. Widely applicable, the flow rates of steam (saturated steam), gases (air, oxygen, nitrogen, coal gas, natural gas, gas, hydrogen, liquefied petroleum gas, hydrogen peroxide, flue gas, methane, butane, chlorine, gas, biogas, carbon dioxide, nitrogen, acetylene, phosgene, oxygen, compressed air, argon, toluene, benzene, xylene, hydrogen sulfide, sulfur dioxide, ammonia), steam, liquids and water, liquids (water, high-temperature water, oil, food liquids, chemical liquids, etc.), liquids, and gases can be measured.

Precautions

Legend

1. Installation of expansion pipe

For small diameters and large flow rates, it is necessary to expand the pipe installation and ensure that the front straight pipe section of the flowmeter is ≥ 15D and the rear straight pipe section is ≥ 5D

2. Installation of shrink tubing

For large caliber and small flow, it is necessary to install a reduction pipe, while ensuring that the front straight pipe section of the flowmeter is ≥ 15D and the rear straight pipe section is ≥ 5D

3. Installation of bent pipes

If the front end of the flowmeter has a 90 ° elbow or T-shaped joint, it is necessary to ensure that the front straight pipe section of the flowmeter is ≥ 15D and the rear straight pipe section is ≥ 5D

4. Installation of two bent pipes on the same plane

If there are two 90 ° elbows at the front end of the flowmeter, it is necessary to ensure that the front straight pipe section of the flowmeter is ≥ 20D and the rear straight pipe section is ≥ 5D

5. Installation of two curved pipes in different planes

If there are two 90 ° elbows at the front end of the flowmeter, it is necessary to ensure that the front straight pipe section of the flowmeter is ≥ 25D and the rear straight pipe section is ≥ 5D

6. Installation of regulating valve

If regulating valves need to be installed before and after the flowmeter, it is necessary to ensure that the front straight pipe section of the flowmeter is ≥ 25D and the rear straight pipe section is ≥ 5D
