Perimeter Projection

A projection perimeter (P.) is a device that is used to measure the circumference. It consists of a light source, an optical device and a measuring arc or hemisphere.

The optical device allows you to change the position, size and brightness of the light spot on the measuring arc or hemisphere. This allows you to accurately measure the circumference and other parameters of the object on which the length is measured.

Perimeter projection is widely used in various fields such as furniture manufacturing, textile industry, automotive industry, etc. It allows you to quickly and accurately measure the length and width of objects, which greatly simplifies the production process and improves product quality.

Projection perimeters are divided into two types: optical and electronic. Optical perimeter. Optical instruments have high measurement accuracy, but require a special source to use them. And the devices themselves are already more expensive. So it's relatively easier to start with an electronic peristaltic meter. The basic principle of operation of electronic mechanisms is to “press the liquid against the measuring head and stop it.” Since all devices are of the type of automatic meters, it is necessary to set the parameters of this procedure directly on the device and install the dispenser. It will allow you to measure volumes in milliliters with an error of up to 0.5%. The devices also differ in the diameter of the edge of the measuring cup. The most common size is from
