Subsea Bullseye Level and Slope Indicator

These subsea bullseye level and slope indicators are used to level or measure the angle of subsea structures and equipment. They are designed to be easily readable by ROV’s and subsea cameras, and have been used successfully on subsea projects down to 6000m (20,000ft). Our experience in designing and building circular bullseye type levels and inclinometers has resulted in a range of products whose performance and price cannot be matched.

Construction

  • Body made entirely from cast acrylic for optical clarity and to reduce overall weight
  • Precision machined and then annealed prior to assembly to maintain strength
  • Top and bottom section chemically welded to form a perfect hermetic seal, keeping manufacturing costs low.
  • 316 Stainless Steel or black ceramic ball resists corrosion
  • Backing disc underside printed with graduations to eliminate parallax error
  • Liquid filled with Glycol to damp ball movement and equalise pressure

Features

  • Background colour eliminates glare for improved visibility from ROV
  • ±3°, ±5°, ±7°, ±10° or ±15° measurement range
  • 250 or 300mm diameter options (others on request)
  • Simple mounting arrangement with 3 holes in flange
  • Custom sizes, ranges and graduations can be made to order
  • Pressure tested to 6,000m (20,000ft)
  • Precision radius gives accurate and repeatable ball movement
  • Scale printed on ball surface to eliminate parallax error
  • Custom built handles and bases to suit customers application. Please click here to see an example.
  • STANDARD SIZES AVAILABLE FROM STOCK
