PROBLEM TO BE SOLVED: To suppress the variation of a flow rate of oil in an oil tank so as to suppress the variation of quality of hardening, in oil hardening processing.SOLUTION: An oil flow rate measurement device 1 for measuring a flow rate of hardening oil in an oil tank includes: a plurality of probes 2 immersed in the oil; a plurality of probe fixing members 3 to which each of the probes 2 is fixed; and a display 4 for displaying a temperature history of each of the probes 2. Temperature sensors 6 are embedded in each of the probes 2. Each of the probe fixing members 3 is provided in a multi-stage shape in a vertical direction, and the plurality of probes 2 are provided to at least two of the probe fixing members 3.SELECTED DRAWING: Figure 2 |
