FIELD: medicine. ^ SUBSTANCE: sensor includes a vessel for liquid, a pressure measuring device and fluid flow channel, an air chamber. The camera is equipped with a support panel, deformable panel, the first junction panel. The pressure measuring device is located outside the vessel to measure the deformation of the deformable panel and is a device for measuring the pressure in the air chamber, which is connected to the inlet/outlet air hole of the air chamber. The fluid flow channel is connected to the inlet. The air chamber includes an opposed panel which is not deformed by pressure and is separate from the deformable panel. The second junction panel is not deformed by pressure and connects the opposing panel with deformable panel to create enclosed airtight space in the said chamber. Some mathematical expressions are introduced, which are satisfied to the values of VA is the volume of air chamber in the initial state, VL - is a vessel for liquid volume in the initial state, and Vr - is the volume of the connecting section. ^ EFFECT: providing measurements without delay and without contact with air. ^ 17 cl, 19 dwg |
