In another example, the material of the bottom of the measuring cup 1 can be adsorbed by a magnet, and the magnetic base is provided with the magnet. For another example, the magnet is arranged on the material of the bottom of the measuring cup 1, and the material of the magnetic force can be adsorbed by the magnet. In this way, stability during the device collecting leakage can be ensured

It should be noted that the non-contact liquid level controller of the applicable type may be selected as needed, and the type of the non-contact liquid level controller is not limited in the present disclosure.
The non-contact liquid level controller 4 is connected with the timer 3, when the liquid level in the measuring cup 1 reaches the first scale, the non-contact liquid level controller 4 is triggered to generate a first control signal, and when the timer 3 receives the first control signal from the non-contact liquid level controller 4, the timer 3 is triggered to start timing;
in the timing process of the timer 3, the measuring cup 1 continuously receives the leaked liquid, so that the liquid level of the measuring cup 1 continuously rises, when the liquid level in the measuring cup 1 rises to reach the second scale, the non-contact type liquid level controller 4 is triggered to generate a second control signal, and the timer 3 stops timing and stores the currently timed duration when receiving the second control signal from the non-contact type liquid level controller 4.
