A vertical limit groove is provided on the outer curved surface of the upper end of the lower overflow pipe, and a vertical limit boss is provided on the inner wall of the upper overflow pipe. An overflow port is fixedly installed on the upper end of the upper overflow pipe, and a secondary scale line for observing the position of the overflow port is provided on the inner wall of the metering tank. A supporting horizontal plate is fixedly installed on the top side end of the metering tank, and an electric telescopic rod is fixedly installed on the middle part of the supporting horizontal plate.
[0008] Preferably, the metering tank is fixedly mounted on the upper end of the support base.
[0009] Preferably, the telescopic part at the lower end of the telescopic cylinder is inclined inward, and is rotatably connected to the lower end of the swing rod through a pin shaft. The telescopic cylinder is connected to an external control air pump through an air pipe.
[0010] Preferably, a transparent plate is fixedly mounted on the inner wall of the observation tank.

[0013] Compared with the prior art, the beneficial effects of the present invention are:
[0014] 1. When the liquid to be measured is discharged into the metering tank, the flow meter of the utility model will detect the flow rate of the liquid passing through the feed pipe. When the liquid discharged into the metering tank through the feed pipe reaches the required flow rate, the discharge of the liquid can be closed. At the same time, when the discharge of the liquid is closed, the liquid in the metering tank exceeding the overflow port will be discharged into the upper overflow pipe through the overflow port and discharged to the outside through the lower overflow pipe, thereby facilitating the measurement of the liquid while the excess liquid will overflow and be discharged to the outside.
[0015] 2. The utility model also controls the electric telescopic rod to be turned on when it is necessary to adjust the upper and lower positions of the overflow port. When the electric telescopic rod is turned on, the overflow port is driven to move up and down. When the overflow port moves up and down, the upper overflow pipe is driven to move up and down in a straight line along the outer curved surface of the lower overflow pipe. The upper and lower overflow capacity heights of the overflow port can be observed through the auxiliary scale lines. When the overflow port moves straight upward, the metering capacity inside the metering tank will increase, and vice versa. This realizes overflow metering of the liquid while facilitating the up and down adjustment of the overflow capacity of the liquid. BRIEF DESCRIPTION OF THE DRAWINGS

A main scale line 11 is provided on the inner wall of the observation groove 10, so that the liquid level inside the metering tank 2 can be observed through the main scale line 11 and the observation groove 10;
[0023] The lower end side wall of the metering tank 2 is fixedly installed with a lower overflow pipe 12, and the upper end of the lower overflow pipe 12 is sealed and movably connected with an upper overflow pipe 13. The outer curved surface of the upper end of the lower overflow pipe 12 is provided with a vertical limit groove 14, and the number of vertical limit grooves 14 is several, which are symmetrically distributed in sequence according to the outer curved surface of the lower overflow pipe 12.

[0024] Working principle: When in use, the utility model discharges the required measured liquid into the metering tank 2 through the feed pipe 3. When the required measured liquid is discharged into the metering tank 2, the flow meter 4 will detect the flow of the liquid passing through the feed pipe 3. When the liquid discharged into the metering tank 2 through the feed pipe 3 reaches the required flow, the discharge of the liquid can be closed. At the same time, when the discharge of the liquid is closed, the liquid in the metering tank 2 that exceeds the overflow port 19 will be discharged into the upper overflow pipe 13 through the overflow port 19 and discharged to the outside through the lower overflow pipe 12, thereby facilitating the measurement of the liquid while the excess liquid will overflow and be discharged to the outside.
[0025] By controlling to open the telescopic cylinder 9, when the telescopic cylinder 9 is opened, the valve stem 6 will be driven to rotate through the swing rod 8. When the valve stem 6 rotates, the valve plate 7 will be driven to swing. When the valve plate 7 swings, the discharge pipe 5 can be opened. When the discharge pipe 5 is opened, the liquid measured in the metering tank 2 can be discharged outward for use. At the same time, when it is necessary to adjust the up and down position of the overflow port 19, the electric telescopic rod 18 is controlled to open. When the electric telescopic rod 18 is opened, the overflow port 19 is driven to move up and down. When the overflow port 19 moves up and down, the upper overflow pipe 13 is driven to move up and down along the outer curved surface of the lower overflow pipe 12. The upper and lower overflow capacity heights of the overflow port 19 can be observed through the secondary scale line 16. When the overflow port 19 moves straight upward, the metering capacity inside the metering tank 2 will increase, otherwise it will decrease, thereby realizing overflow metering of the liquid and facilitating the up and down adjustment of the overflow capacity of the liquid.
