Liquid Level Switch
|
 |
|
|
This microprocessor based liquid level
switch which consumes low power and can be used
for liquids up to 10000 cP and is suitable up to
temperature limits of 200°C. This liquid level
indicator is extremely compact making it
suitable for constricted places.
This single point level switch for liquids
uses the RISC Core micro-controller technology
which makes it reliable & more accurate for
level detection of any liquid or slurry (even
highly viscous up to 10,000 cP). The level 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 Elixir liquid level control switch has no moving
parts and is not affected by the turbulence in
the tank, floating particles, suspensions or gas
bubbles. This makes it a superior choice over
the traditional float switch based level
indicators. If the liquid/slurry service
material is very viscous, Elixir IS the
instrument of choice. The instrument neither
requires adjustments nor is dependent on the
position, thus making it the best option for
liquid level indication in small tanks, pipes
and mixing tanks. |
| Applications |
| You can use the Elixir liquid
level indicator for level detection of all types
of liquids in storage tanks, mixing tanks and
pipe lines having temperature up to 200°C and
viscosity up to 10,000 cP and density greater
than 0.7 gm/c.c. Elixir is suitable for most of
the applications, where traditional float
switches were previously used and for liquids,
which are sticky, corrosive, agitated, splashing
and foaming. |
| Where is it used |
| Liquid level control switch has well used in the
food, power, chemicals, sugar, detergent, steel,
minerals, textile and many other industries.
Anywhere you use a float operated switch for
liquid level indication, Elixir level switch comes as a
better solution. |
| Principle |
| A specially shaped tuning
fork is kept vibrating by piezo-electric
elements at a set frequency. 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. |
