In modern electric teapots to determine the level of water in the body of the kettle establish or to the body of the kettle attach водомерную a tube that is connected with the tank teapot, as communicating vessels, or establish водомерное glass.
Kettles with the water pipe or transparent inserts have the following disadvantages:
1. It significantly increases the complexity of manufacturing the kettle, as the metal or plastic casing should be cut to install transparent inserts, or tube.
2. It is difficult to ensure the tightness of metal teapot in the place of the connection housing with transparent inserts or snorkel because of differences (5-6 times) temperature coefficients of expansion of the metal and plastic (glass) in the temperature range (10-100)deg C.
3. The consumer can hardly see the level filled the kettle with water through the transparent inserts, have to strain your eyes. Besides, tube and insert eventually мутнеют, thus further complicating the visualization of the water level.
