FIELD: measurement equipment.
SUBSTANCE: this invention relates to fluid medium flow controllers, such as fluid or gas flow controllers, and more specifically - to a controller having a flow modifier with pressure registration. The proposed fluid medium flow controller includes a body of a valve, comprising an inlet, an outlet, a throughput valve hole and a control element arranged inside the valve body with the possibility of movement. The control unit comprises a drive connected with the control element, and also a membrane arranged close to a membrane chamber. A probing nozzle comprises the first end, the second end and an intermediate section, at the same time the first end is installed into a position, making it possible to communicate with the membrane chamber, the second end is located close to the outlet, and the intermediate section is located close to the intermediate section of the valve body outlet. The probing nozzle comprises a ledge and a socket-like section, at the same time the socket-like section is located closely to the second end.
EFFECT: increased functional capability of a fluid medium flow controller in each class of accuracy.
