AN ELECTROMAGNETICAL WATER AND HEAT COUNTER

Invention belongs to the class of consumed water and heat meters in the thermofication heating systems of closed and open types. The meter consists of three debit sensors (1, 2, 3), four temperature sensors (4, 5, 6, 7), indicator (8), voltage polarity commutator (9), analogous commutator (10), interference compensation block (11), microchip (12) with the control block (13), memory block (14), standard output signal block (15), input amplifier (16), normalising amplifier-commutator (17), bearing resistor (18) connected to one of the inputs of the polarity commutator (9) and analogous commutator (10), which digital data link is connected to the data link of the microchip (12), while its command link is connected in parallel to the microchip's (12) command block (13), analogous signal commutator (10), normalising amplifier-commutator (17), interference compensation block (11) and the voltage polarity commutator (9) while the output data and address link is connected in parallel to the indicator (8), memory block (14), standard output signal block (15), having digital and analogous inputs. The other inputs of the tetragonal commutator (10) are connected with the outputs of the temperature sensors (4, 5, 6, 7), while the sixth input is connected to the output of the normal amplifier-commutator (17), the inputs of which are connected to each of the debit sensors (1, 2, 3) via the interference compensation block (11) and input amplifier (16). Each of the debit sensors is composed of two serially connected excitation curls (19, 20), two signal electrodes (21, 22) and measuring curls, serially connected by the outputs in the chain of the signal electrodes. The excitation curls (19, 20) of the debit sensors outputs are connected to the voltage polarity commutator (9).
