The Officine Orobiche float & board level indicators provide a simple, reliable and low-cost measurement system for any type of storage vessels. Thanks to this type of level indicators, you can check at a glance the liquid level, even from a long distance. The installation kit is complete and ready to be used; the range includes a standard non-vapor sealed version (TLQ-38W) and a watertight version (TLQ-41W). Both are available in a wide variety of materials including special alloys and thermoplastic materials. On request, it is possible to supply a 20” “Manhole Flange” on which it is possible to obtain a rectangular  hatch (generally with 400x152 mm size) to allow inspection of the inside of the tank.
