FIELD: measurement technique. ^ SUBSTANCE: invention is intended for hot water flow measuring. Watermetre contains divided by nonmagnetic screen 4 chamber with impeller 2 and chamber of reducing-counting mechanism with two dials. Spiral temperature detector (TD) 3 is connected by its one end with screen 4 and by its other end - with ring-shaped magnet 5 with possibility of interaction through screen with magnet 8. Reducing-counting mechanism contains magnetic cam clutch 10 which switches rotation transmitted from impeller to one of dials depending on water temperature. Readings of one dial correspond to "hot" water flow (T>40C) and of the other dial - to "cold" water flow (T<40C). Presence of TD which can be made as bimetallic plate or tube filled with liquid makes possible to determine border of "cold" and "hot" water. ^ EFFECT: invention improves measurement efficiency due to possibility of separate water recording depending on its temperature. ^ 3 cl, 2 dwg |
