Magnetrol Vizual and Atlas magnetic level indicators
Posted: 24 October 2003
Vizual and Atlas are 2 separate Magnetic Level Indicator product
designs of Magnetrol International — each built to serve different
needs. Vizual is a basic, robust and low cost level gauge series,
while Atlas is the ultimate complete product offer allowing custom
made features.
Magnetrol’s decision to split the existing MLI offer into
2 separate designs is inspired by a long tradition in building mechanic
controls and the knowledge that a flexible design can not be built
economically.
Vizual units have basic features but are precision engineered and
manufactured to guarantee a long lifetime.
The use of standard material and dimensions is the basis of the
Vizual design. The standard 2” gauge is made of 316/316L (1.4401/1.4404)
and incorporates a 316 TI (1.4571) float with ring magnet. The indication
rail can be either in polycarbonate with rollers or aluminium with
stainless steel flags.
The unique rail design (click on system) allows the mounting of
a polyester scale, bi-stable DPDT micro switch / reed switch or
transmitter options without the need for straps. Vizual is designed
for operating conditions up to 90 bar (600lbs rating)/ +280°C.
Atlas gauges are almost not limited by design criteria to meet
the customers’ specifications. A wide choice of metal alloys
and plastics are standard available. Atlas cages can be either 2”,
2,5” or 3” following density/pressure rating.
Atlas gauges are standard equipped with an inert gas filled indication
rail to eliminate the possibility of condensation inside the rail.
Magnetrol has designed a float with a flux system, containing precisely
aligned vertical magnets to reach a higher magnetic coupling between
the float’s magnet and the indication rail / external mount
output devices such as switches and transmitters. Atlas floats are
designed following the operating conditions. These conditions can
mount up to 310 bar (2500 lbs rating) / +540°C.
Vizual and Atlas maintain high quality standards. Float designs
are sealed (non vented nor gas filled), cage construction is per
Magnetrol’s standard in compliance with PED regulations and
safety approvals on output devices include ATEX intrinsically safe
and explosion proof.
Both Vizual and Atlas units are produced at Magnetrol Zele in Belgium.
