Product DescriptionIntroductionF56 metal Tube Float Flow meter Series are used for measureinstantaneous and accumulated flow rate of liquid, gas and steam inclosed pipelines. It is suitable for metering flow value on site orelectronic remote. The measuring principle is based on thehydrodynamic effects, This makes float moving from bottom to top invertical Pipe. As the displacement of float is in related to flowrate, which can be read from the indicator by means of the magneticdrive system in non-contact form . Also, flowmeters outputelectrical signal (4-20)mA / hart communication protocol with high/ low limit Warning switches/integrating flow PCB broad can beconfigured.
Operating principle
F56 series variable area flowmeters is made up of flow sensor andflow indicator. Float is placed vertically inside of conicalmeasuring tube and can freely move up and down along the conicaltube owing to hydrodynamic effects.A high-performance permanentmagnet is set inside float, by this way the magnetic field aroundpermanent magnet will change along with the float moving up anddown.When fluid keeps a stable flow value and float locates in adynamic balance state in position, the magnetic field aroundpermanent magnet keeps constant also.The magnetic signal will betransmitted in non-contact form by means of the flow Indicatormechanically connected to conical tube. In another word, theindicator is able to detect and process flow value of liquid bymagnetic drive system and finally the corresponding flow rate valuecan be read from the scale on site. Also it can indicate outputs asstandard electrical signal (4-20)mA / hart communicationprotocol.
Measurement of gases
When the valve is opened suddenly in pipeline or pressure isunstable during metering gases, airflow will be pulsating. As aresult, float moves up and down along the conical tube ceaselessly.In the meantime, system is out-of-control since pointer swingingconstantly lead to output signal instability. In this conditions,damping device must be installed inside measuring tube (seefig.2-2). The damping device become a self-centering damper ofpreventing block through special design
and precision work of numerical control machine centre. The dampingdevice is consists of aluminum oxide ceramic (purity is 99.99%) andcharacterized by a long service life, resistant to corrosion,structure novelty, practicality better.
