The system to treat a motor exhaust gas flow has a storage tank holding a urea and water solution, with a dosage unit to feed the solution into the exhaust gas flow near the selective catalyst reduction unit. An electronic evaluation unit measures the concentration of the urea and water solution, to set the required dosage levels. The system to treat a motor exhaust gas flow (1) has a storage tank (6) holding a urea and water solution (5), with a dosage unit (7-13) to feed the solution into the exhaust gas flow near the selective catalyst reduction unit (3). An electronic evaluation unit (15) measures the concentration of the urea and water solution, to set the required dosage levels. At least one pressure sensor (14) is at the solution holding tank, together with a thermal sensor (16).
