<p>PROBLEM TO BE SOLVED: To provide a water level and water temperature measurement system that can be easily installed in a small space and is capable of performing temperature measurement in a water surface region way down to near the water bottom in accordance with a water level fluctuation.SOLUTION: A water level and water temperature measurement system 1 has an underwater placement unit 1a comprising a float 2, a temperature sensor 3, and a sinker 4, a water level gauge 10, a thermometer 12, and a take-up device 6. The sinker 4 is tided to a guide wire 8. The guide wire 8 is inserted into the float 2 in a loose-insertion state, serving as a guide for the movement of the float 2 in the vertical direction. The float 2 has a water level measurement wire 10a connected thereto that is tied to the water level gauge 10, detecting a water level by a delivery length thereof. The temperature sensor 3, provided at the lower end of the float 2, has a lead wire 12a connected thereto that is tied to the thermometer 12. An excess portion of the lead wire 12a is wound up in spiral form to the upper end of the float 2.</p> |
