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

3. By using advanced signal processing amplifiers and unique filtering techniques, interference signals generated by pressure fluctuations and pipeline vibrations are effectively eliminated, greatly improving the anti-interference ability of the flowmeter and providing excellent stability for small flow rates.

4. The unique functions of time display and real-time data storage ensure that internal data will not be lost and can be saved for a long time under any circumstances.

5. The overall power consumption of the machine is extremely low, and it can operate on long-term power supply with internal batteries, 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.

This series of products complies with the national JJG198-94 "Verification Regulations for Velocity Flowmeters" and Q/320831C S003-2007 "LUXZ Series Intelligent Spiral Vortex Flow Meter" enterprise standards.

This series of products has been verified and approved by the National Instrument Meter Main Explosion Safety Supervision Station (NEPSI), and complies with the relevant provisions of national standards GB3836.1-2000 and GB3836.2-2000. The explosion-proof mark of the explosion-proof type is Exd Ⅱ Bt4.

2、 Structure and working principle of HQ-LUXZ series intelligent vortex gas flowmeter

1. Flow meter structure (see Figure 1)

1. Shell 2, vortex generator 3, flow sensor 4, pressure sensor 5, flow integrator 6, temperature sensor 7, guide vane

2. Working principle of flowmeter (see Figure 2)

When the fluid passes through a spiral vortex generator, it is forced to vigorously rotate around the center of the vortex generator, forming a vortex flow. The vortex flow accelerates, passes through the contraction section along the flow direction, and the flow intensity increases. When the vortex enters the diffusion section, it undergoes a secondary rotation under the action of the backflow of the guiding fluid, and the frequency of the secondary vortex is proportional to the flow rate. When the flowmeter is designed, the vortex frequency is linearly related to the flow rate over a wide range of flow rates. This frequency is detected by a piezoelectric sensor and processed by a flow integrator. Display the instantaneous flow rate and cumulative total amount of flow, and transmit the corresponding 4-20mA current signal for output.

3. Working principle of flow integrator (see Figure 3)

The principle block diagram of the flow integrator is shown in Figure 3. The CPU receives the pulse signal from the preamplifier and the pressure and temperature signal obtained through the A/D converter, and finally calculates the instantaneous flow rate, cumulative flow rate, temperature, and pressure values. Meanwhile, display these parameters on the LCD. The flow display can display both standard flow and non standard flow. The three function keys on the instrument panel,<SET>key,<INC>key, and<SHT>key, can be used to set internal parameters.
