摘要

The metering device uses a counter (3,6) with a vol. flowmeter (4) and a circulation temp. sensor (7), coupled to a control and processing circuit (5) which is linked to a display (9). The latter is incorporated in a common housing with the circulation temp. sensor (7), or in a common housing with a return feed temp. sensor (10). The control and processing circuit may also be contained within this housing or in a common housing with the vol. flowmeter (4). ADVANTAGE - Provides simple read-out of display.
