As inventors of the
reflex glass we retain world market leadership and more experience
in level gauge applications than other manufacturer in the world.
They are five type of level gauges in the Klinger range :
- Reflex glass
- Transparent glass
- Bi - colour
- Magnetic
- Glass tube
Reflex Gauges
On steam boiler where the pressure does not exceed 32 bar,
reflex gauges are the best and most economical solution. In
the process industry too, the reflex gauges given the clearest
indication, regardless of whether the medium is water clear
or coloured. |
Transparent
Gauges
Transparent gauges are offered for the pressure range up to
120 bar. Transparent gauges on steam boiler are provided with
an illuminator to ensure prefect visual indication. If the medium
is dirty, viscous on aggressive, flat transparent glasses surface
can be protected by mica shields against serious attack by the
medium. Bi-colour Gauges
Klinger have developed bi-colour level gauges
for steam pressure up to 180 bar. These give clearest indication
possible. Such gauges are used exclusively on steam boilers.
Observation can be made by monitoring via-closed-circuit T.V.
The KLINGER
liquid level gauges are suitable for virtually all media,
pressure up to 400 bar and temperature ranging from -196 C
bis +400 C. |
The well proven Klinger
Magnetic Level Gauge is particularly suitable for duties where
dangerous and toxic liquids or gasses are involved and where
the following features, benefits and options are required:
- Immediate and accurate response
to level changes, giving clear and sharp legibility
- Continuous control of liquid
level
- Local and remote display
- Alarm switching facilities
- Robust, shockproof and completely
sealed for safety
- No leakage to atmosphere
- Particularly suitable for
dangerous or toxic fluids
|
 |
- Ideal for liquid interface
applications.
- Powerful omni-direction magnet
system - guide - free float
- Display can be rotated through
360º irrespective of float position
- Automatic float warning
- High pressure capability -
up to 157 bar unvented
- High temperature capability
- standard up to 400º C
- Standard SG range 0.4 - 2.2
- Unlimited length
- Top mounted options
- PTFE / PFA lined, PP and PVDF
and uPVC versions
- Simple to engineer and easy
to install
- Eliminates preventives maintenance
- An economical alternative
to:
Conventional level gauges and other level measuring systems

| Klinger gauge glasses are manufactured from
high quality Borosilicate Glass "extra hard"
with low thermal expansion co-efficient. They are especially
treated to ensure:
- Exceptionally high mechanical strength
- High resistance against thermal shock
- Resistance against static temperature
differential in the glass.
|
Circular Sight Glasses "extra-hard"
borosilicate glass for visual control of chemical and
physical processes. |
|
| The quality of a sight glass
depends mainly on the chemical composition and mechanical strength
of the glass material. Uniform glass quality is maintained through glass
analyses and acid / alkali tests. The mechanical strength
is attained through thermal pre-stressing. In this procedure
the sight glass is brought to a high temperature then quickly
cooled - rather as in increases the bending strength and shock
resistance of the glass to the values stipulated in the standard.
Optical control
of the prestressing is carried out with the aid of a polarization
filter: the stress lines are made visible at the edge of the
sight glass as interference colours. Glass which has not been
thermally pre-stressed shows no stress lines and has much
lower mechanical strength. |
| Shut-off Fittings
for Liquid Level Gauges |
 |
 |
The shut-off fittings play a major role in the operating
safety and functioning of gauges. Even the first KLINGER liquid
level gauge was equipped with a quick and reliableshut-off fitting,
made in the company's own production facilities. Drain cocks are a standard are a standard
equipment of the shut-off units. Both, gauge cocks and gauge
valves may be retightened without difficulty. |
