Background

The open channel weir notch flowmeter is a channel flow metering device, and is extensively used for metering open channel water delivery flow in the links of cross-drainage basin water transfer, agricultural irrigation and intermediate water discharge, etc. its working principle is that a standard weir notch is set in the open channel, and the water level is measured according to the defined position, and because the flow rate passed through the weir notch and water level are formed into correspondent relationship, it can be converted into instantaneous flow rate according to flow rate formula or empirical relational expression of both them from measured real-time water level. The Bashel trough flowmeter is the most widely and mature open channel weir trough flowmeter at present, and accounts for more than 95% of the flow rate. The flowmeter for the Parshall tank is mainly composed of the Parshall tank and the open channel flowmeter, the Parshall tank can have various specifications, and the open channel flowmeter device has the functions of measuring water level in real time and converting the water level into instantaneous flow at a specified position, and has the functions of conventional flowmeters such as accumulated flow, data storage and real-time transmission.

In summary, the accuracy of the flow metering of the baschel tank flow meter is mainly affected by two aspects: the accuracy of the Parshall tank sizing and the accuracy of the open channel flowmeter water level measurements. The machining materials of the Parshall groove are greatly different according to different sizes, and comprise PVC, iron plates, stainless steel plates, concrete and the like. Due to factors such as processing level, use conditions and ambient temperature, the actual size and the designed size of the used Parshall cell are larger and larger, and the accuracy of flow measurement is affected. Meanwhile, the accuracy of water level measurement of the open channel flowmeter is deeply influenced by the installation position of the open channel flowmeter, the water surface floating amplitude and the like, and further the accuracy of flow measurement is also influenced.

In the prior art, the water level is mainly measured by the water level sensor and then converted into an instantaneous flow value according to the type of the Parshall tank, but the fluctuation range of the water level is severe, so that the measured data of the water level sensor is inaccurate, and meanwhile, the water level sensor is easy to incline, so that the measurement error is caused.
