04.09 How are tank accessories installed with low ceiling heights?

Tanks inside buildings are often installed in rooms with limited ceiling heights. This can be a problem for the installation of tank equipment. For example, there may be 3 feet of clearance above the tank and with a tank diameter of 8 feet a level transmitter installed into the top of the tank may be 10 feet in total length/

One solution is to provide floor openings and access doors in the floor slab above the tank, but in most cases this is impractical.

Level transmitters are available from several manufacturers in flexible models which can bend to be inserted into the tank. Drop tubes and suction pipes may be installed as segmental pipes which are joined as they are installed into the tank.

It is recommended that gauges and instruments be installed at the end of the tanks where they can be readily inspected and maintained without having to have a person gain access to the top of the tank.
