FIELD: measurement technology; internal combustion engines. ^ SUBSTANCE: flowmeter has case, which is covered by protecting casing. Electromagnet unit and electromagnet valves are tightly fastened to the casing. Internal space of case is divided to two parts by means of elastic diaphragm. Electromagnet valves are connected of photodiode and light-emitting diode and are disposed at top part of case. Photodiode and light-emitting diode are tightly fixed onto internal part of case. One more control element is made in form of flag, which is rigidly connected, with diaphragm. Elements for getting measuring signal are disposed at lower part of case. The elements include photodiode and light-emitting diode, which are both connected to electron unit. Plank is provided with optical raster and it is also disposed at lower part of case as well as measuring circuit. Two branches of measuring circuit intend for measuring total and current discharge. Any branch has digital output. ^ EFFECT: improved precision of measurement. ^ 1 dwg |
