External Chambers

& Stilling Wells

External chambers are utilized for mounting Shridhan

or other process level instruments to a vessel. This external

mounting allows for isolation of the instrument during routine

maintenance while ensuring uninterrupted plant operation.

It is particularly useful when in-tank restrictions prevent

instruments mounting directly on the vessel. Chambers

are used to obtain a level or interface measurement

from the outside of a process vessel. Custom solutions

are offered for high temperature and corrosion resistance,

including special high temperature resistant painting on them. 

Chambers are used in many applications
for following types of instruments - 

  • Radar transmitters - Guided Wave
    and Non-Contact 

  • Tuning fork switches 

  • Vertical float switches 

  • Horizontal float switches 

  • Magneto strictive level transmitters 

  • Displacer level switches and transmitters 

  • Hydrostatic level transmitters 

  • With Magnetic level gauges
    (dual chamber assemblies) 

Features

  • Global quality assured design and manufacturing according to various International standards. 

  •  Conforms to Pressure Equipment Directive (PED) 2014/68/EU for liquids in Groups 1 and 2. 

  •  Industry standard weld neck flanges are used throughout, increasing safety by minimizing stress levels and the number of welds. 

  •  All welds are full penetration - to increase integrity and reduce corrosion. 

  •  Drain options for even easier maintenance of the instrument. 

  • Optional vent allows gas in the upper zone above the liquid to be vented off

Stilling wells

Stilling wells are cylindrical cages installed within tanks to protect level instrumentation from fluid agitation,

which could cause measurement errors. They effectively dampen disruptions such as waves, turbulence, and reduce

foaming, providing a stable surface for accurate level measurement. Stilling wells are compatible with float and displacer

level switches, float-operated level transmitters, as well as ultrasonic and radar sensors.
