Ciepłomierze / Chłodomierze
The ultrasonic heat meter is one of the flattest devices on the market and, thanks to its removable calculator, can be easily installed even in particularly inaccessible places. The ultrasonic meter can be installed variably as a heat, cold or combination meter. The current consumption, the due date and the due date value can be conveniently recorded with just the push of a button via a display loop.
