1、 Product Overview

LUX spiral vortex flowmeter is a new type of gas flow meter that adopts advanced microprocessing technology and has the advantages of strong functionality, wide flow range, simple operation and maintenance, and easy installation and use. Its main technical indicators have reached the advanced level of similar foreign products, as shown in Figure 1.

2、 Product principle

The flow profile of a flow sensor is similar to the profile of a Venturi tube. Place a set of spiral guide vanes on the inlet side, which force the fluid to generate intense vortex flow when it enters the flow sensor. When the fluid enters the diffusion section, the vortex flow is subjected to backflow and begins to undergo secondary rotation, forming a gyroscopic vortex precession phenomenon. The precession frequency is directly proportional to the flow rate and is not affected by the physical properties and density of the fluid. By measuring the secondary rotation precession frequency of the fluid with the detection element, good linearity can be obtained over a wide range of flow rates. The signal is amplified, filtered, and shaped by a preamplifier into a pulse signal proportional to the flow rate, and then sent to the microprocessor for integration processing along with temperature, pressure, and other detection signals. The measurement results (instantaneous flow rate, cumulative flow rate, temperature, pressure data) are displayed on the LCD screen.

3、 Product Features

1. Built in pressure, temperature, and flow sensors with high safety performance, compact structure, and beautiful appearance.

2. On site display of temperature, pressure, instantaneous flow rate, and cumulative flow rate.

3. By adopting a new type of signal processing amplifier and unique filtering technology, the interference signals generated by pressure fluctuations and pipeline vibrations are effectively eliminated, greatly improving the anti-interference ability of the flowmeter and making small flow rates have excellent stability.

4. The unique functions of time display and real-time data storage ensure that internal data will not be lost in any situation.

5. The whole machine has extremely low power consumption and can operate for a long time with internal battery power supply, making it an ideal on-site display instrument without the need for external power supply.

6. The anti-theft function is reliable, with password protection to prevent parameter changes.

7. The header can rotate 180 degrees freely, making installation convenient.

5、 Installation skills

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.
