Product Description
Introduction
F*6 Metal Tube Variable area air Flow meter Series are used for
measure instantaneous and accumulated flow rate of liquid, gas and
steam in closed pipelines. It is suitable for metering flow value
on site or electronic remote. The measuring principle is based on
the hydrodynamic effects,This makes float moving from bottom to top
in vertical Pipe. As the displacement of float is in related to
flow rate, which can be read from the indicator by means of the
magnetic drive system in non-contact form . Also, flowmeters output
electrical signal (***0)mA / hart communication protocol with high
/ low limit Warning switches/integrating flow PCB broad can be
configured.
Operating principle
F*6 series variable area flowmeters is made up of flow sensor and
flow indicator. Float is placed vertically inside of conical
measuring tube and can freely move up and down along the conical
tube owing to hydrodynamic effects.A high-performance permanent
magnet is set inside float, by this way the magnetic field around
permanent magnet will change along with the float moving up and
down.When fluid keeps a stable flow value and float locates in a
dynamic balance state in position, the magnetic field around
permanent magnet keeps constant also.The magnetic signal will be
transmitted in non-contact form by means of the flow Indicator
mechanically connected to conical tube. In another word,the
indicator is able to detect and process flow value of liquid by
magnetic drive system and finally the corresponding flow rate value
can be read from the scale on site. Also it can indicate outputs as
standard electrical signal (***0)mA / hart communication
protocol.
Measurement of gases
When the valve is opened suddenly in pipeline or pressure is
unstable during metering gases, airflow will be pulsating. As a
result, float moves up and down along the conical tube ceaselessly.
In the meantime, system is out-of-control since pointer swinging
constantly lead to output signal instability. In this
conditions,damping device must be installed inside measuring tube
(see fig.**2). The damping device become a self-centering damper of
preventing block through special design and precision work of
numerical control machine centre. The damping device is consists of
aluminum oxide ceramic (purity is *9.*9%) and characterized by a
long service life, resistant to corrosion, structure novelty,
practicality better.
