To ensure the accuracy of measurements, the installation of the temperature sensing element should follow these guidelines: it should be placed within the pipeline in such a way that it has full contact with the fluid; moreover, the element should face the flow direction of the medium being measured, or at least be in flow alignment with it. ( ) A. The working end of the temperature sensing element should be located at the point in the pipe where the flow velocity is highest. B. The working end of the temperature sensing element should be located at the point in the pipe where the flow velocity is lowest. C. The cover of the junction box should face upward. D. The cover of the junction box should face downward. E. There must be sufficient insertion depth. A C E
