DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] like Figure 1-Figure 4 As shown, a magneto-actuated liquid level gauge type self-reading working volume device, bolts are arranged between the magneto-actuated liquid level gauge 5 and the magneto-actuated liquid level gauge mounting tube 4, the magneto-actuated liquid level gauge 5 and the magneto-actuated liquid level gauge mounting tube 4 are detachably connected by bolts, the magneto-actuated liquid level gauge 5 is mounted in the magneto-actuated liquid level gauge mounting tube 4 by bolts, the magneto-actuated liquid level gauge mounting tube 4 and the third fixing frame 12 are sleeved, the first fixing frame 8 and the working volume device cylinder 2 are detachably connected by the second screw 11, and the glass tube liquid level gauge 3 with a scale is detachably connected to the first fixing frame 8 by the first screw 9.

[0023] Install the magneto-fluid level gauge 5 and the magneto-fluid level gauge mounting tube 4 together through bolts, and then install the magneto-fluid level gauge mounting tube 4 and the working measuring instrument cylinder 2 together through the first fixing bracket 8 and the second screw 11, and then threadably install the glass tube level gauge 3 with a scale and the first fixing bracket 8 through the first screw 9 and the second fixing bracket 10, and the installation of the device is completed. The disassembly is the same.

[0024] like Figure 1-Figure 4 As shown, the magneto-liquid level gauge installation tube 4 and the working measuring instrument cylinder 2 are connected through the second connecting tube 13 and the first connecting tube 6. The sum of the internal volumes of the magneto-liquid level gauge installation tube 4 and the working measuring instrument cylinder 2 is the total volume of the working measuring instrument, which is designed to meet the calibration requirements of the total volume of the measuring instrument and the graduation volume of the metering neck.

[0025] The conventional reading method is to directly read the actual volume value on the glass tube level gauge 3 with a scale. Each scale is generally 1 / 1000 of the nominal volume. However, sometimes when reading, the eyes are not in a horizontal position with the liquid level, resulting in visual errors caused by refraction, etc.; the more accurate reading method is: the reading accuracy of the magnetic level gauge 5 is generally not more than 1mm, and when the measuring neck is designed, the rise distance per millimeter is not higher than 4 / 10000 of the nominal volume of the measuring instrument, so the reading precision and reading accuracy are improved. The magnetic ring of the magnetic level gauge 5 floats up as the water level in the magnetic level gauge installation tube 4 rises. After the meter is checked, the magnetic level gauge 5 reads the height signal of the actual liquid level, and the actual water consumption is converted through the equipment software. The reading accuracy is much higher than the visual reading method, and it can cooperate with the water meter calibration device software to increase the automation of the equipment.

[0026] It should be noted that the utility model is a magneto-level gauge type self-reading working measuring instrument. When in use, the magneto-level gauge 5 and the magneto-level gauge mounting tube 4 are mounted together by bolts, and then the magneto-level gauge mounting tube 4 and the working measuring instrument cylinder 2 are mounted together by the first fixing frame 8 and the second screw 11, and then the glass tube level gauge 3 with a scale and the first fixing frame 8 are threadedly mounted together by the first screw 9 and the second fixing frame 10, and the installation of the device is completed, and the disassembly is similar.

[0027] The conventional reading method is to directly read the actual volume value on the glass tube level gauge 3 with a scale. Each scale is generally 1 / 1000 of the nominal volume. However, sometimes when reading, the eyes are not in a horizontal position with the liquid level, resulting in visual errors caused by refraction, etc.; the more accurate reading method is: the reading accuracy of the magnetic level gauge 5 is generally not more than 1mm, and when the measuring neck is designed, the rise distance per millimeter is not higher than 4 / 10000 of the nominal volume of the measuring instrument, so the reading precision and reading accuracy are improved. The magnetic ring of the magnetic level gauge 5 floats up as the water level in the magnetic level gauge installation tube 4 rises. After the meter is checked, the magnetic level gauge 5 reads the height signal of the actual liquid level, and the actual water consumption is converted through the equipment software. The reading accuracy is much higher than the visual reading method, and it can cooperate with the water meter calibration device software to increase the automation of the equipment.
