The rotary vortex flowmeter integrates flow, temperature and pressure detection functions, and can automatically compensate for temperature, pressure and compression factors. It is a meter for gas measurement in petroleum, chemical, electric power, metallurgy and other industries.
The working principle of the swirling vortex flowmeter:
The flow sensor's flow profile is similar to that of a venturi tube. A set of spiral guide vanes are placed on the inlet side, and when the fluid enters the flow sensor, the guide vanes force the fluid to produce a vigorous swirl flow. When the fluid enters the diffusion section, the vortex flow is subjected to the recirculation, and the second rotation starts to form a gyro-type 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 element measures the secondary rotation precession frequency of the fluid to obtain good linearity over a wide flow range. The signal is amplified, filtered, and shaped by the preamplifier into a pulse signal proportional to the flow rate, and then sent to the microprocessor for integration processing together with the temperature, pressure and other detection signals, and finally the measurement is displayed on the liquid crystal display. Results (instantaneous flow, cumulative flow and temperature, pressure data).
Main features of the vortex flowmeter:
1, no mechanical moving parts, not easy to corrode, stable and reliable, long life, long-term operation without special maintenance;
2, using 16-bit computer chip, high integration, small size, good performance, the machine features strong;
3. Intelligent flowmeter integrates flow probe, microprocessor, pressure and temperature sensor. It adopts built-in combination to make the structure more compact, can directly measure the flow, pressure and temperature of the fluid, and automatically track the compensation and compression factor in real time. Amend
4. Double detection technology can effectively improve the detection signal strength and suppress the interference caused by pipeline vibration;
5. Adopting the domestic leading intelligent seismic technology, effectively suppressing the interference signals caused by vibration and pressure fluctuations;
6, using Chinese character dot matrix display, display more digits, the reading is intuitive and convenient, can directly display the volume flow in the working state, the volume flow under the standard state, the total amount, as well as the medium pressure, temperature and other parameters;
7, using EEPROM technology, parameter settings are convenient, can be permanently saved, and can save up to one year of historical data;
8, the converter can output frequency pulse, 4 ~ 20mA analog signal, and has RS485 interface, can be directly connected with the microcomputer, the transmission distance can reach 1.2km;
9. Multi-physical parameter alarm output, which can be selected by the user;
10, the flow meter head can be rotated 360 degrees, easy to install and use;
11. In conjunction with the company's FM data collector, remote data transmission pressure and temperature signals can be input to the sensor via the Internet or telephone network, and the interchangeability is strong;
12, the whole machine has low power consumption, and can be powered by internal battery or external power supply.
