A modern boiler room requires numerous control systems to ensure a reliable and trouble free operation, some of them governed by Regulations. Diverse regulations prevail in some countries although there is a increase trend to homogenize them into International Regulations. Our Technical Dept can provide good and professional advice on regulations and minimum requirements. One of the most important regulations refers to the unattended boiler room control aimed at ensuring the minimum water level at the boiler drum. Each steam generator should be provided with a water level control system or a remote visual level gauge with two indicators in order to show compliance with The TRD 421 Standard. In an automatic water level control system, the measuring sensors and associated controller govern the feed water control valve or the start up / stop pump.
- Visual Bicolour Boiler Level Gauges
Visual Gauge, commonly referred to as a Sight Glass or Level Gauge, is the only technology available to provide “Direct” indication of steam drum water level thus satisfying the ASME Boiler and Pressure Vessel Code requirements.
The Aquarian 3000 Visual Bi-Color Water Level Gauge is rated to 3000psi (207Bar) and produces
a red/green image to indicate the water level in a high pressure steam drum.
With a one piece trapezoidal shape body, light projected through steam produces a red image.
Light projected through water is refracted and produces a green image.
Viewable from wide angles, the solid state LED Illuminator provides a clear red/green image and
offers a 10 year maintenance free service life.
Two discs of premium V-1 quality mica protect and extend the glass life and the Belleville washers
eliminate hot re-torqueing. With nipple ends or flanged connections, this gauge fulfills
the requirements of the ASME Boiler and Pressure Vessel Code.
The standard features of this high performance gauge reduce plant maintenance and the total cost of operation.
Optional Intrinsic Safety Protection and Explosion Proof Protection is available to meet hazardous area classification requirements
All components are assembled on to pressure water column level and can be supplied integrally skided.
