Measurement apparatus, measurement method, and computer-readable recording medium

[0037]Below, an example embodiment of the present invention will be described with reference to FIGS. 1 to 8.

[0038][Apparatus Configuration]

[0039]First, the configuration of a measurement apparatus according to the present example embodiment will be described with reference to FIG. 1. FIG. 1 illustrates an example of the measurement apparatus.

[0040]As shown in FIG. 1, the measurement apparatus 1 has a detection unit 2, a time specification unit 3, and a supplied amount calculation unit 4. Also, the detection unit 2 has a measurement unit 5 and an output unit 6. Further, the measurement device 1 shown in FIG. 1 is an apparatus capable of managing the supplied amount of a liquid while suppressing an increase in the cost of equipment (for example, drip irrigation equipment) using a tubular structure 7.

[0041]Of these, the detection unit 2 detects a pressure according to a shape change of the tubular structure 7, whose shape changes according to the supplied amount of a liquid that flows th

[First Modified Example]

[0118]In above step A3, when calculating the supplied amount FR of the liquid during the supply time TP, the supplied amount calculation unit 4 used the supplied amount FF measured by the flow measurement unit 22. In this first modified example, the supplied amount calculation unit 4 uses a number N of drips provided in each section 31 and a supplied amount FD of the irrigation water per unit time supplied from one drip to calculate the supplied amount FR. That is, in the modified example in step A3, the supplied amount calculation unit 4 calculates the supplied amount FR of the liquid during the supply time TP by multiplying the supply time TP in the section 31, the number N of drips provided in that section 31, and the supplied amount FD of the irrigation water per unit time supplied from one drip. See above Formula 2.

[Second Modified Example]

[0119]As a modified example of step A3, a supplied amount of fertilizer in liquid obtained by mixing the liquid with the fertilizer may be calculated. Specifically, when the fertilizer is mixed with the liquid using a specific mixing ratio, the supplied amount calculation unit 4 calculates a supplied amount FP of the fertilizer during the supply time TP by multiplying the supply time TP in the section 31, the supplied amount FF of the liquid per unit time in the section 31, and a mixing ratio R. See above Formula 3.
