1. The menu unlock password for the Aoxin ASL-20 swirl vortex flowmeter is 1485. The effective operation time after unlocking is 10 minutes. 1. Unlocking operation steps - When the instrument panel is in normal display state, press the [S] key. At this time, the bottom of the LCD screen will display "CD", indicating that the password input state has been entered. -Set the password high code to "1485" by pressing the [A] key (increase value) and the [Z] key (shift). -Finally, press the [S] key again to confirm and unlock the menu.
2. Important bad feature description - Password validity: After successful unlocking, the instrument panel will only maintain an operable time of 10 minutes. If it exceeds the time limit, it will automatically re lock. -Initial state: Before unlocking, the instrument panel will not respond to hunger or any other password input except for the unlock password.

2. Working principle of vortex flowmeter

The flow profile of the 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 Instruction Manual for Spiral Vortex Flow Meter

flow is subjected to backflow and begins to undergo secondary rotation, forming a gyroscopic vortex precession phenomenon. The precession frequency is 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 conditions. The signal is amplified, filtered, shaped, and converted into a pulse signal proportional to the flow rate by a pre roll amplifier, and then sent to the microprocessor for integration processing along with temperature, pressure, and other detection signals. Finally, the measurement results (instantaneous flow rate, cumulative flow rate, temperature, pressure data) are displayed on the LCD screen. The structure of the vortex flowmeter is compact, mainly composed of a housing, a vortex generator, sensors (temperature, pressure, flow), a rectifier, a bracket, and a converter. The conditions for using a spiral gas flowmeter are: ambient temperature: -30 ℃~+55 ℃ relative humidity: 5%~95% medium temperature: -30 ℃~+80 ℃ atmospheric pressure: 86kPa~106kPa
