The Sapcon Fluidofork (SLF Series) is a tuning
fork based liquid level indicator for single
point control. The instrument has an adjustable
switching delay for covered and uncovered
conditions. The electronics is integral with the
fork and can be mounted in different ways such
as wall/back panel mounting or remote mounting.
If the use is in hazardous area, you could
choose the flame proof version. You also have
the flexibility of choosing the insertion
length.
The Fluidofork (SLF... Series) has no moving
parts and is not affected by the turbulence in
the tank, floating particles, suspensions or gas
bubbles. If you are using any viscous liquids,
Fluidofork can be your best bargain. The
instrument neither requires adjustments nor it
is dependent on the position, thus making it the
best choice for liquid level indication in small
tanks, pipes and mixing tanks.
Applications
Liquid level detection is
easy with Fluidofork. It can be used for all
types of liquids in storage tanks, mixing tanks
and pipe lines having temperature between -20°C
and +80°C (standard version), viscosity up to
10,000 cP, density greater than 0.7 gm/c.c.
Fluidofork is suitable for most of the
applications, where float switches were
previously used and for liquids, which are
viscous, corrosive, agitated, splashing and
foaming.
Where is it used
Fluidofork (SLF… series)
liquid level switches are successfully used in
processing plants for liquids having viscosity
up to 10,000 cP in food, power, chemicals,
sugar, detergent, steel, minerals, textile and
many other industries. It also has replaced the
float operated switches in some of the
applications. It is also not affected by
electrical properties of the service material.
Principle
A specially shaped tuning
fork is kept vibrating by piezo-electric
elements. The frequency of the fork changes when
the tines are immersed in the liquid. The change
in the frequency is detected and used for
switching a relay. The output contacts of the
relay can in turn be used for annunciation or
control.
