Philemon Vortex - Precession Flow Meters

• Without movable mechanical parts insideincorruptible,reliable&stablelong service lifelong time runing no need special maintenance.
• Adopt 16bits computer chiphigh integritysmall sizegood performancepowerful functions.
• Intelligent flow meter integrate the flow sensormicro-processorpressure and temperature sensor togetheradopt the embedded type make the structure compact,it can measure the flowtemperature and pressureand carry out the real-time tracking compensation and compression factor amendment.
• Adopt the double checking technology could enhance the measured signal strength effectivlyand restrain the interference caused by pipeline vibration.
• Adopt the advanced intelligent anti-vibration technologyrestrain the interference signal caused by vibration and pressure fluctuate.
• Adopt the Chinese character dot matrix display screenwith more display bitand convenient readingit can display the volume flow rate under working conditionvolume flow ratetotal flow and medium pressuretemperature parameters under standard condition.
• Adopt EEPROM technologyconvenient parameter settingcan save permanentlyit can save the one year historal data.
• The flow converter could output frequency pulse4~20mA analogue signaland has RS485 interferenceit could connect computer networkthe transmission distance can reach 1.2km.
• Multi physical quantity parameters alarm outputthe end user can select any of them.
• Flow meter converter could rotate 360degreeeasy and convenient installation.
• Match with our company FM model data gatherit could carry out the remote data transmission via internet or telephone or internet.
• Pressuretemperature signal is flow sensor input methodstrong interchangeability.
• Lower power consumptioncould use the battery powered and connect the external power also.

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).
