Example 1-recording of level change: after the real-time liquid level meter which automatically records the passing floating highest position and the passing floating lowest position is installed and connected to the monitored equipment, the starting equipment is switched on, the working liquid level of the equipment is recorded, as shown in figure 2-3, when the liquid level of the equipment rises, the floater 3 rises along with the liquid level, the floater 3 drives the high position recording part 4 to move upwards along the floating groove 2, the high position recording part 4 pushes against the upper end of the floater 3 to move together, when the high position recording part 4 floats upwards, and the rear end of the high position recording part 4 passes through the high position limiting baffle blade 12, the upward acting force of the floater 3 enables the high position recording part 4 to slide upwards along the front end surface of the high position limiting baffle blade 12, because of the soft elastic material of the high position limiting baffle blade 12, the smoothness of the floating movement of the high position recording part 4 can be effectively kept, and the high position recording part 4 can not be clamped between the inner wall of the floating groove 2 and the front end surface of the high position limiting baffle blade 12, after the high-order recording part 4 completely passes through the high-order spacing fender leaf 12, the high-order recording part 4 continues to move up along with the liquid level, and when the high-order recording part 4 floats up and reaches the current highest liquid level, the lower end card of the high-order recording part 4 is put on the high-order spacing fender leaf 12 stretches out, and the recorder records the current highest liquid level through the scale observation part 26.

If the subsequent liquid level continues to rise, the high-level recording part 4 continues to rise along with the floater 3, passes through the upper high-level limiting baffle blade 12, is clamped on the high-level limiting baffle blade 12 at a higher position, and a recorder records the highest liquid level of the latest equipment operation through the scale observation part 26.

When the liquid level of the equipment descends, the high-position recording part 4 keeps clamped on the extending end of the high-position limiting baffle blade 12, the low-position recording part 5 is abutted against the lower part of the floater 3, the floater 3 and the low-position recording part 5 descend along with the liquid level, when the rear end of the low-position recording part 5 descends to pass through the low-position limiting baffle blade 20, the low-position recording part 5 slides downwards along the front end surface of the low-position limiting baffle blade 20 under the action of the gravity of the floater 3, the low-position recording part 5 can effectively keep the descending fluency of the low-position recording part 5 due to the soft elastic material of the low-position limiting baffle blade 20, so that the low-position recording part 5 cannot be clamped between the inner wall of the floating groove 2 and the front end surface of the low-position limiting baffle blade 20, and continues to descend along with the liquid level after the low-position recording part 5 completely passes through the low-position limiting baffle blade 20 until the low-position recording part 5 stays at the current lowest liquid level, the upper end of the low-position recording part 5 is clamped below the extending end of the low-position limiting baffle blade 20, the recorder records the current minimum level through the graduated view 26.

When the subsequent liquid level continues to descend, the low-level recording part 5 descends along with the floater 3, passes through the lower low-level limiting baffle blade 20 and is clamped on the lower low-level limiting baffle blade 20, and a recorder records the lowest liquid level of the operation of new equipment through the scale observation part 26.

Example 2-reset level gauge operation: when the equipment liquid level data record is obtained, the reset operation is needed.

First, reset the high position limit mechanism, as shown in fig. 6, press down the high position reset connecting rod 9 through the holding part 23, make the high position reset guide plate 10 slide down and move along the sliding chute 6, drive the rear end of the high position limit connecting rod 11 to rotate along the first movable moving bolt 15, simultaneously the high position limit connecting rod 11 is lifted upwards along the fixed movable bolt 16 at the center, lift the high position limit baffle 12 to flush with the inner wall of the floating chute 2, because there is no block of the high position limit baffle 12, the high position recording part 4 drops to the top of the float 3 under the action of gravity, and the reset of the high position recording part 4 is completed. Then the holding part 23 is loosened, under the action of the contraction pulling force of the high-position reset connecting rod spring 13, the high-position reset guide plate 10 drives the high-position reset connecting rod 9 to reset upwards along the sliding groove 6, when the upper end of the first limiting block 14 of the high-position reset connecting rod 9 is propped against the upper end surface of the outer shell 1, the high-position reset guide plate 10 stops moving, and meanwhile, the high-position limit baffle blade 12 and the high-position limit connecting rod 11 descend to return to the initial position, and the reset of the high-position limit mechanism 7 is completed.

Then, the low-position reset connecting rod 17 is pressed down through the holding part 23, so that the low-position reset guide plate 18 slides down along the sliding groove 6 to drive the rear end of the low-position limit connecting rod 19 to rotate along the second movable moving bolt 21, meanwhile, the low-position limit connecting rod 19 rotates downwards along the fixed movable bolt 16 at the center, the low-position limit baffle blade 20 is lowered to be flush with the inner wall of the floating groove 2, and the low-position recording part 5 rises to be below the floater 3 under the action of liquid surface buoyancy due to no blockage of the low-position limit baffle blade 20, so that the reset of the low-position recording part 5 is completed. Then the holding part 23 is released, under the action of the contraction pulling force of the low reset connecting rod spring 24, the low reset guide plate 18 drives the low reset connecting rod 17 to reset and move downwards along the sliding groove 6, when the lower end of the second limiting block 25 of the low reset connecting rod 17 is propped against the lower end face of the outer shell 1, the low reset guide plate 18 stops moving, and meanwhile, the low limit stop blade 20 and the low limit connecting rod 19 descend and return to the initial position, and the resetting of the low limit mechanism 8 is completed. And completing the total resetting of the liquid level meter.

The invention has simple structure, convenient operation and complete functions, can be used as a daily monitoring real-time liquid level meter of equipment, can record historical highest liquid level and lowest liquid level data reached in the running process of the equipment at any time, and is convenient for operators and supervisors to more intuitively know the past running condition of the equipment and to more quickly trace the problem of abnormity generated in the running process of the equipment.

It should be understood that the above-described embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments.
