Description

technical field [0001] The invention belongs to the field of liquid temperature measurement, and in particular relates to an integral liquid temperature contact measurement device and a measurement method. Background technique [0002] Free-falling liquid temperature measurement has applications in many engineering fields, such as: using the pipeline water discharge valve to indirectly measure the temperature of the working fluid in the pipeline, and the temperature distribution measurement of the cooling tower water, etc. Taking a mechanical ventilation cooling tower group as an example, multiple cooling towers are arranged side by side, and the water return pools of each cooling tower are connected to each other. In order to study the thermal performance of a cooling tower unit, it is necessary to obtain accurate cooling tower water temperature, especially when it is necessary to analyze the detailed aerodynamic distribution of cooling tower fill, drift eliminator, sprinkl...

Problems solved by technology

In practice, this method will cause the measured temperature to not accurately reflect the real-time value of the liquid temperature in the pipeline due to the volume of the bucket (or beaker) being too large or too small, and the flow rate control.
