The invention relates to measurement technology and can be used in measuring the flow rate and volume of liquid and gaseous media and of steam in the thermal power, gas, chemical and other branches of industry. The technical result which the claimed invention aims to achieve is providing for the high sensitivity of a device at low flow rates, which allows for raising the useful signal level at minimal flow rates, and for decreasing the minimum sensitivity threshold, which allows for decreasing the minimum flow rate at which generation begins. Said technical result is achieved in that a jet generator contains a jet discrete element comprising a supply nozzle, a working chamber formed by the inner walls of two guides which deviate outward from a nozzle outlet, and a separator having a concave deflector, a U-shaped cutout is provided on the outer side of each of the guides, the sides of which cutout form an angle of no more than 90° with the tangent to the direction of flow in feedback channels. The angle between guides may be between 15 and 40°, preferably 30°, and the supply nozzle may be provided with a nozzle. |
