Problems solved by technology

[0006] In addition, the Chinese patent CN 102830731 A in the prior art discloses an integrated flow and temperature control device, including: a housing; a two-way electric ball valve is provided in the housing, which controls the size and direction of the flow according to the control command; the interpolation type The digital temperature measuring device measures the temperature of the fluid in the pipe in real time; the two-way turbine flowmeter transmits the instantaneous or cumulative flow in real time by outputting electromagnetic, pulse or current signals; the integrated control circuit board controls the two-way electric ball valve to measure the temperature of the fluid in the pipe in real time And the flow rate is controlled by a two-way electric valve, but it cannot eliminate the influence of impurities in the fluid on the measurement data. The measurement data is inaccurate and unstable, which has an adverse effect on the stable control of intelligent water flow, and is not conducive to improving the temperature control of the dam. Crack resistance and construction level

Description

technical field [0001] The invention belongs to the technical field of intelligent water flow temperature control construction of water conservancy and hydropower projects, and in particular relates to an integrated flow temperature intelligent monitoring device. Background technique [0002] The existing ultrasonic flowmeters are mainly divided into two categories according to the principle: the time difference method (also called the time delay method) and the Doppler method. Among them, the working principle of Transit Time Ultrasonic Flowmeter is to use a pair of ultrasonic transducers to alternately (or simultaneously) send and receive ultrasonic waves, and indirectly measure the flow of the fluid by observing the forward and reverse propagation time difference of ultrasonic waves in the medium. An indirect measure of flow rate, and then calculate the flow rate from the flow rate. This method requires ultrasonic waves to penetrate the fluid, so the fluid must not conta...
