They measure the flow of water by means of a turbine that turns with the passage of water.<br /> The number of turns is converted to total consumption.
The water passes through fixed volume chambers that are filled and emptied.<br /> Counting these operations determines the total volume.
They combine mechanical metering with an electronic totalizer and show consumption on a digital display.
They measure water flow without any moving parts.<br /> The entire measurement and recording process is electronic, guaranteeing high precision.
Only the turbine is in contact with water.<br /> The drive train and totalizer are completely dry.<br /> Transmission is magnetic, without direct contact with water.<br /> Electronic meters fall into this category.
Part of the drive train is in contact with water, but the totalizer remains dry.<br /> The connection between the drive train and the totalizer is made by means of a magnetic coupling.
The entire drive train is submerged in water, but the totalizer is encapsulated and protected in a special liquid (such as glycerin).<br /> The transmission is done mechanically.
All components (turbine, drive train and totalizer) are in contact with water.<br /> There are no isolated parts and the transmission is completely mechanical.
