swirl type flow meters advantages
- Accuracy:1.5% standard,1% optional
- Medium Temperature:-20~80℃
- Flow Range:1.2 m³ ~ 3600 m³
♦ Without movable mechanical parts inside, incorruptible,reliable&stable, long service life, long time runing no need special maintenance.
♦ Adopt 16bits computer chip, high integrity, small size, good performance, powerful functions.
♦ Adopt the advanced intelligent anti-vibration technology, restrain the interference signal caused by vibration and pressure fluctuate.
♦ Adopt EEPROM technology, convenient parameter setting, can save permanently, it can save the one year historal data.
♦ The flow converter could output frequency pulse, 4~20mA analogue signal, and has RS485 interference, it could connect computer network, the transmission distance can reach 1.2km.
♦ Multi physical quantity parameters alarm output, the end user can select any of them.
♦ Flow meter converter could rotate 360degree, easy and convenient installation.
♦ Match with our company FM model data gather, it could carry out the remote data transmission via internet or telephone or internet.
♦ Pressure, temperature signal is flow sensor input method, strong interchangeability.
♦ Lower power consumption, could use the battery powered and connect the external power
The flow sensor flow profile like the venturi tube shaped wire (pic 2), install one group sprial guide buffle in the side of entrance, while the fluid enter the flow sensor, the guide buffle will press the fluid generate strong swirl flow, when the fluid enter expansion section, the swirl flow will generate second time rotating under the effect of counterflow, and shape the swirl precession phenomenon of gyroscopic shape. The precession frequency in proportion to flow volume, it will not influenced by fluid physical property and density, when get the fluid second time precession, the testing element will get better linearity in the wide flow range. The signal will be magnified via front amplifer, filting and transform into the pulse signal in proportion to flow rate, then send to the micro processor undertake totalizering process with the temperature, pressure testing signal, fianlly it will display the measured result on the LCD displayer ( instantaneous flow total flow and temperature, pressure data).
