FIELD: measurement equipment.SUBSTANCE: water stage gauge for watercourses of a mountain and piedmont area includes a canal or a river, a water level recorder. The water state gauge is also equipped with a vertical pipe separated into two unequal parts with a vertical partition, and a vertical wall of the first part is equipped with upward inclined water-receiving slots-windows opposite to the flow. At the same time the pipe on top is equipped with a chamber with a recorder and communicates two unequal parts via a float and a stop element installed in a socket, built into the second part of the vertical pipe, communicated with the canal by calibrated openings, and is made in the form of two valves connected to each other as capable of axial displacement relative to each other. Besides, one of the valves is made in the form of a tilted cone with a perforated base and an axial hole in the cone top, through which one end of the guide stem is pulled, being rigidly connected at the bottom with the other valve in the form of a conical plug, and the other end of the stem is placed in the cavity of the second part of the pipe. At the same time the valve in the form of the conical plug in the upper part is additionally equipped with a guide stem stretching via a hole into the base of the tilted cone in its centre and connected by the other end with the float by means of a flexible drive.EFFECT: increased accuracy and reliability of flow measurement of nonpressure flows with rapid flow regime.3 dwg |
