FIELD: measuring equipment.
SUBSTANCE: invention relates to a measuring sensor of vibration type for measuring held in fluid conduit, in particular a gas, liquid, powder or other flowable material, in particular for measuring density and/or percentage of mass flow, in particular also summed in a certain time total slot mass flow flowing in a pipeline, at least periodically with mass flow rate of more than 1,000 t/h, in particular more than 1,500 t/h medium. Measurement sensor includes a housing receiver (71), located at inlet end of which is formed by having eight, respectively, spaced apart flow openings (201A, 201B, 201C, 201D, 201E, 201F, 201G, 201H) located on intake side of flow separator (20,1) and located at outlet end of which is formed by having eight, respectively, spaced apart flow openings (202A, 202B, 202C, 202D, 202E, 202F, 202G, 202H) located on side of separator of outlet (202) stream; and a system of pipes in formation of an eight-fluidic parallel connected flow paths connected to separator (201, 202) curved flow measuring tubes (181, 182, 183, 184, 185, 186, 187, 188) for fluid, each of eight measuring tubes, respectively, located at inlet end of measuring tube includes, respectively, one of separator flow openings (201) flow and located at outlet end of measuring tube includes, respectively, one of separator flow openings (202) stream. Electromechanical device (5) of field sensor is used to generate and/or maintain mechanical oscillation of measuring tubes (181, 182, 183, 184, 185, 186, 187, 188). Distinctive feature of sensor is that measuring tubes (181, 182, 183, 184) are curved and arranged in such a manner that height to calibre ratio D18/Q18 pipe system defined by ratio of calibre D18 of first measuring tube to maximum lateral elongation Q18 pipe system as measured from highest point of first measuring tube (181) to highest point of third measuring tube (183), is greater than 0.05.
EFFECT: technical result is creation of sensor of high sensitivity and quality fluctuations, which even at high flow rates up to 1,000 t/h ensures a small pressure loss, possibly less than 3 bar, and that also with a large nominal width of 100 mm is most compact design and also suitable for gaseous media and/or for environments with significantly changing temperatures.
