The invention relates to control-measuring equipment. Strain indicator for volumetric-weight liquid density measuring device and volumetric-weight liquid measuring device on its basis include flow-sensitive pipe, strain indicator and measuring device. Strain indicator includes sensitive spring element with glued tensiometric transformers, flexible elastic pipe that is tightly connected to outlet of inlet pipeline and to inlet of flow-sensitive pipe, inlet means for connection connected to outlet of inlet pipeline and rigidly connected to fixed with respect to earth support, and outlet means for connection rigidly connected to flow-sensitive pipe. Each of sensitive elements is connected to means for connection at outside of flexible pipe. The outlets of tensiometric transformers are connected to inputs of measuring device and strain indicator is deformed under effect of weight of flow-sensitive pipe. Flexible pipe is arranged as silphon that is rigidly attached to its ends to means for connection. Each of sensitive elements is arranged as rigid beam that is rigidly connected to those means for connection, at that the beams are arranged along the silphon and have possibility to prevent deformation of tension-indicator in vertical direction at elongation or compression of silphon. Technical result of the invention is in increase of accuracy of measurement. |
