Abstract

The utility model relates to a Venturi automatic water measuring device, which relates to a device for measuring water flow in a water channel. The device is composed of a Venturi tank, an ultrasonic water level sensor, a computer and a monitor; the Venturi tank is built in the canal and divides the canal into two parts; one of the two ultrasonic water level sensors is installed in the canal wall before the inlet of the Venturi tank , and the other is installed in the tank wall of the Venturi tank; two ultrasonic water level sensors are respectively connected with the computer for data collection and storage, and the monitor is connected with the computer. The working method of the device is: when the water in the canal flows through the Venturi tank, a certain drop will be generated. Two ultrasonic water level sensors can measure the corresponding water level, and the drop can be calculated by the computer. Then, calculate the flow velocity and flow rate of the water through the drop, and store it in the computer for viewing at any time. The device can measure the flow of the water channel all-weather and fully automatically, so the error is small, and no manual monitoring is required.

Description

Venturi automatic water measuring device

technical field

The utility model relates to a Venturi automatic water measuring device, which relates to a device for measuring water flow in a water channel.

Background technique

At present, current meters are mostly used to measure the water flow in the canal. Due to the characteristics of small flow, frequent changes, large amplitude changes, high sediment, many impurities, and slow slope decline in the end-stage channels of the plain irrigation area, there are large errors in calculating the full-day flow from the instantaneous flow measured by the current meter. The workload is also very large, and the degree of automation is not high, and it is not easy for farmers to monitor, so it is urgent to research, introduce and develop more advanced water measuring equipment.

Utility model content

The purpose of the utility model is to provide a device that can automatically and accurately measure the water flow in the canal.

The device is composed of a Venturi tank, an ultrasonic water level sensor, a computer and a monitor; the Venturi tank is built in the canal and divides the canal into two parts; one of the two ultrasonic water level sensors is installed in the canal wall before the inlet of the Venturi tank , and the other is installed in the tank wall of the Venturi tank; the two ultrasonic water level sensors are respectively connected with the computer for data collection and storage, and the monitor is connected with the computer.

The working method of the device is: when the water in the canal flows through the Venturi tank, a certain drop will be generated. Two ultrasonic water level sensors can measure the corresponding water level, and the drop can be calculated by the computer. Then, calculate the flow velocity and flow rate of the water through the drop, and store it in the computer for viewing at any time. The device can measure the flow of the water channel all-weather and fully automatically, so the error is small, and no manual monitoring is required. Data can be viewed at any time.
