Water metres with protective cover

Protective cover

— special cover covering the counter scale. Usually, such a cover is closed, it is opened only to check the readings. Such a cover protects, first of all, the transparent plastic with which the scale is covered — from bumps, scratches and dirt; thanks to this, the plastic remains transparent for a long time, does not become foggy and does not interfere with reading data from the scale. However, the role of the cover is not limited to this, it often provides additional protection for the case as a whole; and in some models, sensors are mounted in the cover to transmit data from the metre, used in remote control systems. Note that all these functions can be provided both in industrial and domestic metres (see "Water temperature").
