A flow rate and direction monitoring device suitable for turbid fluid

Abstract

The invention discloses a turbid fluid monitoring device, which comprises a touch rod, a connecting piece, an elastic damping body, a base, a light pipe, an optical lens, an optical positioning sensor, a light source emitting module and a data processor; the optical lens and the optical positioning The sensor and the touch rod at the rest position are coaxial; the scattered light emitted by the light source emitting module is exported through the light pipe, and is projected onto the optical positioning sensor after being concentrated by the optical lens; the data processor is connected with the optical positioning sensor by electrical signals, Based on receiving the coordinate information of the center of the light spot provided by the optical positioning sensor, the angle at which the current touch rod deviates from the rest position is obtained, and the flow velocity and flow direction of the fluid are calculated. The invention has low manufacturing cost, low energy efficiency, can be installed and used in batches, and can monitor fluid information in real time in harsh environments such as turbid water bodies.

Description

technical field [0001] The invention belongs to the fluid measurement technology, and relates to a flow rate and direction monitoring device suitable for turbid fluids. Specifically, a damping rod type flow rate and direction measurement device is proposed, which can be used for real-time monitoring of turbid fluids. Background technique [0002] In the field of fluid measurement, the current measurement technologies and methods mainly include advanced fluid measurement methods such as ultrasonic Doppler technology, laser technology, and hot-wire hot-film velocimetry technology. However, some of these technologies and equipment are expensive, and some are inconvenient to use. As an airborne device, it is installed on a space-constrained aircraft. With the deepening of human activities in shallow water such as offshore and lakes, it is becoming more and more important to obtain shallow water current information. The fluid turbidity in these areas is relatively high. Large, wh...
