What Is An Automatic Level?



civil surveyor course in Rawalpindi

The automatic level is one of technology's more recent versions of the construction level. Technical Data used in the field explained in civil surveyor course in Rawalpindi, How is the automatic level different from earlier versions of construction levels such as the wye and dumpy level? In order to understand what an automatic level is, we must first know a little about construction levels in general.
Construction levels can be compared to carpenter's levels. Carpenter's levels are used to determine if two points a few inches apart have equal elevation or are horizontal. Like the carpenter's level the construction level incorporates the spirit level, which is the little slightly curved glass vial filled with a colored spirit. In this case the spirit is alcohol with a bubble floating in it. But in order to transfer a horizontal line a distance to another point, construction levels were developed with the spirit vial attached to a telescope. The telescope is mounted on a vertical axis, about which it can swing horizontally and is adjusted by four leveling screws. All of this makes up the instrument which is mounted on a tripod to stabilize it and to bring it up to the operator's eye. Some more details of civil surveyor course in Rawalpindi are as under.
Examples of earlier versions of the construction level that utilized the spirit vial are the wye level, also written "Y level"; the dumpy level; and the tilting dumpy level. The wye has the spirit vial attached to the telescope. The telescope rests on a horizontal bar that is rigidly attached to the vertical axis and adjusted by three to four leveling screws. The wye is unique in that the telescope can be unclamped and removed from the horizontal bar, turned end for end, and replaced. This is done when testing the bubble for adjustment. The wye is generally no longer available as a new instrument.
