Product Description
Series of intelligent precessing vortex gas flow meters
Adopting the latest microprocessing technology, it has the advantages of strong function, wide flow range, simple operation and maintenance, and convenient installation and use. This intelligent precessing vortex gas flow meter It integrates flow, temperature and pressure detection functions and can automatically compensate for temperature and pressure. Its main technical indicators have reached the advanced level of similar foreign products. It is widely used in various gas measurement in petroleum, chemical industry, electric power, metallurgical coal and other industries.
Structure
Intelligent precession vortex gas flow meter
It consists of the following seven basic components (picture)
, vortex generator, shell, Intelligent flow meter totalizer, temperature sensor, pressure sensor, piezoelectric crystal sensor, decyclator
Working principle
The flow profile of the flow sensor of the intelligent precessing vortex gas flow meter
is similar to The profile of the venturi tube (picture). A set of spiral guide vanes is placed on the inlet side. When the fluid enters the flow sensor, the guide vanes force the fluid to produce a violent vortex flow. When the fluid enters the diffusion section, the vortex flow begins to rotate twice due to the backflow, 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. The detection By measuring the secondary rotational precession frequency of the fluid, the element can obtain better linearity within a wider flow range. The signal is amplified, filtered, and shaped by the preamplifier and converted into a pulse signal proportional to the flow rate, and then sent to the microprocessor together with detection signals such as temperature and pressure for integration processing, and finally the measurement results are displayed on the LCD screen. (Instantaneous flow, cumulative flow, temperature, pressure and other data).
Main features
Built-in pressure, temperature and flow sensors, with high safety performance, compact structure and beautiful appearance.
Display temperature, pressure, instantaneous flow and cumulative flow.
Using new signal processing amplifiers 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 flow meter and enabling excellent stability for small flow rates.
It has the function of time display and real-time data storage. No matter what the situation, it can ensure that the internal data will not be lost and can be saved permanently.
The power consumption of the machine is extremely low, and it can run on long-term power supply from the internal battery. It is an ideal local display instrument without external power supply.
The stolen function is reliable and has password protection to prevent parameter changes.
The head can be rotated at will and is easy to install.
The converter can output frequency pulses and ~analog signals, and has an interface that can be directly connected to the computer network, and the transmission distance can reach meters.
The machine has low power consumption and can be powered by internal battery or external power supply.
