In step S310, a first measurement error value is determined according to the first measurement value and the first average value.

It should be noted that the first average value is selected as the first liquid level reference value.

The second measurement error value is a standard deviation calculated from the first measurement value and the average value. The multiple measurement can not only obtain the measurement value with higher precision, but also monitor the liquid level measurement data in real time.

For example, if the second liquid level measuring device measures m times the second measured value is Y₁，Y₂，Y₃… Ym, a second average value Y, i.e. the second average value Y, can then be obtained from these m second measured valuesSecond measured value Y from m measurements₁，Y₂，Y₃…, the standard deviation Pm of the current mth measurement is calculated from Ym and the second average value Y, i.e. the standard deviation PmThe standard deviation Pm is the second measurement error value. By measuring the liquid level data for many times, the change of the liquid level data can be monitored in real time.

In some embodiments, referring to fig. 5, fig. 5 is a liquid level measuring method according to another embodiment of the present invention, which includes, but is not limited to, step S510, step S520, and step S530.

It should be noted that the calculation method of the remeasurement error value is the same as that of the first measurement error value and that of the second measurement error value, and is not described herein again.

When the second measurement value from the second liquid level measurement device is obtained to recheck the first measurement value from the first liquid level measurement device, but after the second measurement value is checked, it is found that the second measurement value cannot meet the accuracy requirement, that is, the second measurement error value is greater than the error threshold value, and the first measurement value needs to be obtained again to obtain the second measurement value. And determining a remeasurement error value according to the remeasurement value and the first liquid level reference value, and if the remeasurement error value is smaller than or equal to an error threshold value, indicating that the remeasurement value meets the precision requirement, outputting the remeasurement value as liquid level measurement data. The second liquid level measuring device can recheck the first measuring device, and similarly, the first liquid level measuring device can also recheck the second measuring device, a closed feedback network is formed between the first measuring device and the second measuring device, and accurate measurement of liquid level measuring data is realized through mutual cooperation of the first measuring device and the second measuring device.

When liquid level height measurement is carried out, a measurement instruction sent by a user or computer software is received, a first measurement value from a first liquid level measurement device is obtained in response to the instruction, a first measurement error value is determined according to the first measurement value and a preset first liquid level reference value, and whether the first measurement error value is larger than a preset error threshold value or not is judged. And if the first measurement error value is smaller than or equal to the error threshold value, outputting a first measurement value as liquid level measurement data. And if the first measurement error value is larger than the error threshold, acquiring a second measurement value of a second liquid level measurement device, determining a second measurement error value according to the second measurement value and a preset second liquid level reference value, and judging whether the second measurement error value is larger than the preset error threshold. And if the second measurement error value is smaller than or equal to the error threshold value, outputting a second measurement value as liquid level measurement data. If the second measurement error value is larger than the error threshold value, the first measurement value measured by the first liquid level measurement device is obtained again to obtain a remeasured value, and the remeasured error value is determined according to the remeasured value and the first liquid level reference value and whether the remeasured error value is larger than the error threshold value is judged.

The accommodating area 710 and the U-shaped pipe 720 are made of transparent materials, so that the liquid level of the accommodating area 710 and the liquid level of the U-shaped pipe 720 are conveniently observed to be flush, and liquid level measurement is performed. For example, the material of the accommodating section 710 and the U-shaped tube 720 may be quartz glass.

The pressure-taking communicating pipe 730 and the constant temperature heater 740 are arranged on the first liquid level measuring device 620, so that the liquid pressure and the temperature on the two sides of the U-shaped pipe 720 are the same, the liquid in the U-shaped pipe 720 is ensured to be static, and the liquid level measuring data is prevented from being inaccurate due to the flowing of the liquid in the U-shaped pipe 720. The U-shaped tube 720 is provided with scales for reading the liquid level measurement data. The heating temperature of the constant temperature heater 740 may be adjusted by a program or manually.

In some embodiments, referring to fig. 8, the level measurement system 610 further includes a containment region 710, the containment region 710 for containing a liquid to be measured, the second level measurement device 630 comprising:

the lifting assembly 810 is arranged beside the containing area 710, and scales are arranged on the lifting assembly 810 and used for indicating the liquid level height of the liquid to be measured in the containing area 710;

a measuring assembly 820, the measuring assembly 820 disposed on the lifting assembly 810, the measuring assembly 820 comprising:

a measurement circuit 821, the measurement circuit 821 being provided with an indicator light 822;

the first conductive probe 823 and the second conductive probe 824 are electrically connected to the measurement circuit 821, respectively, the first conductive probe 823 is disposed in the liquid to be measured in the accommodation region 710, and the second conductive probe 824 is used for contacting the liquid to be measured;

the measuring assembly 820 moves up and down along the lifting assembly 810 so that the second conductive probe 824 contacts the liquid level to be measured, when the conductive probe 824 contacts the liquid level to be measured, a closed loop is formed between the measuring circuit 821 and the first conductive probe 823 as well as between the measuring circuit and the second conductive probe 824, and the indicator light 822 is on.

It should be noted that the second liquid level measuring device 630 measures the liquid level by using the conductivity of the liquid to be measured. When the liquid level to be measured is the tin liquid level and the second liquid level measuring device 630 is used for measuring the height of the liquid level of the tin liquid, the lifting component 810 adjusts the measuring component 820 to move up and down, so that the second conductive probe 824 moves up and down, when the second conductive probe 824 contacts the tin liquid, a closed loop is formed between the measuring circuit 821 and the first conductive probe 823 as well as the second conductive probe 824 due to the conductivity of the tin liquid, and the indicator light 822 is on. The indicator 822 lights up to indicate that the second conductive probe 824 is in contact with the liquid level of the molten tin to be measured, and the liquid level data measurement can be performed, otherwise, the lifting assembly 810 continues to adjust the measuring assembly 820 until the second conductive probe 824 is in contact with the liquid level of the molten tin to be measured. Wherein, be equipped with the scale on the lifting unit 810, can be used for the reading of the tin liquid level measured data that awaits measuring.

The liquid level measuring system 610 performs the measuring method according to the embodiment of the first aspect of the present invention, and the first liquid level measuring device 620 and the second liquid level measuring device 630 cooperate with each other, so that the accuracy of the measured data is improved.
