Description

Equipment for measuring flow of open channel
Technical Field
The utility model belongs to the technical field of flow measurement, concretely relates to an equipment for measuring open channel flow.
Background
The existing open channel flow measurement methods include two, one is to adopt a measuring weir, and the other is to adopt a radar flowmeter for measurement. The measurement principle of the water measuring weir is that the upstream and downstream water levels of the water measuring weir are measured and converted into flow according to an empirical formula or an experimental curve, and a certain water level difference is required between the upstream and downstream water levels to realize the flow measurement, otherwise, the measurement cannot be carried out or the measurement accuracy is low. For example, when the head difference along the path of the open channel is small, the measuring weir can generate head loss to influence the channel water passing, and the flow measurement can not be realized. When the downstream of the equivalent weir is provided with water retaining objects such as a gate and the like, the measurement precision of the water measuring weir can be greatly reduced. Although the radar flowmeter has high measurement precision and convenient use, the price is too high.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve is that current open channel flow measurement precision is not high, the technical problem of high price to an equipment for measuring open channel flow is provided.
For solving the technical problem, the utility model discloses the technical scheme who adopts does:
