What is a hose spirit level

Hose spirit is a device that measures horizontal on the structures. It can be measured much more accurately than traditional spirit level. Hose spirit is not very complex from a structural point of view. Basically, these are just two vessels that connect a hose that is filled with water. The containers are usually made of glass or plastic and are about one and a half centimeters in diameter and a height of about two and a half centimeters. The pots are marked in centimeters. Unlike a common spirit level, the hose type must be operated by two people. If they are well-sampled, they can achieve the same precision as geodetics with optical devices.
