ABLE's range of magnetic level gauges offer clear indication of
liquid level in any chamber configuration required to suit process connections. Standard chamber designs or customised chamber configurations can be built on short delivery times to suit customer requirements. Standard options include switches, reed chain transmitters, magnetostrictive transmitters or insulation for cryogenic applications. Exotic chamber materials or economic 'mini' chamber versions, particularly for refridgeration applications, are also available.
How Magnetic Level Indicators Work
The ABLE magnetic level gauge incorporates a float which contains an integral magnet. The buoyant float rises
and falls with the liquid or interface level whilst the magnet 'flips' the indication mounted externally to the chamber. The white and
red indication flaps represent air and liquid or the interface level
respectively.
The magnetic level gauge can be mounted
in various orientations, typically onto the side
or top of a vessel.
Magnet System
Each of the coloured flaps contains
a small magnet which rotates through 1800 when passed by the bar magnet within the float.
The bar magnet design does not lose magnetic field
strength even at temperatures of 4500C,
guaranteeing continuous operation in the most extreme
applications.
The indication rail magnetic field
is interlocked by the individual magnets in each
of the flaps, which ensures a stable indication
under the most severe operating conditions such
as vibration, fast changes in liquid level (surging)
and de-gassing / boiling of the product.
Floats
ABLE Floats are specifically calibrated
to match the conditions of the vessel. The density,
operating pressure and temperature are taken into
account, ensuring that the inferred level is accurate
and repeatable.
