Calibration device of water level measuring equipment

Abstract

The invention discloses a calibration device of water level measuring equipment. The calibration device of the water level measuring equipment comprises a water supply module, a main display module and an auxiliary display module, wherein the main display module and the auxiliary display module adopt liquid level scale plates. The water supply module comprises three pipe lines which are connected with each other through communicating pipes, wherein a pump outlet check valve, a pump and a pump inlet check valve are arranged on the third pipeline, an inlet at the bottom end of the third pipeline is communicated with a water source, the first pipeline is connected with the main display module through a first manual valve and a first flexible pipe, and the second pipeline is connected with a measured open container or the auxiliary display module through a second manual valve and a second flexible pipe. According to the calibration device of the water level measuring equipment, the pump is used for pouring water in the communicating pipes, and the liquid level of the open container is accurately measured according to the main display module and the water level of the measured open container, wherein the main display module and the water level of the measured open container are communicated with the communicating pipes. The calibration device of the water level measuring equipment can also respectively measure the height of two measured points through the main display module and the auxiliary display module and work out the relative height difference between the two points. The calibration efficiency and the precision can be greatly improved, work difficulty and operation difficulty of staff can be reduced, the structure is simple and utilization is convenient.

Description

technical field [0001] The invention relates to a calibration device for measuring equipment, in particular to a calibration device for water level measuring equipment. Background technique [0002] At present, for the safe operation of the device, many devices are equipped with water level measuring equipment, but these water level measuring equipment cannot be directly calibrated or verified at present, and can only be calibrated by other equipment. The calibration process includes such as measuring Liquid height, height difference between two points, etc. In the actual operation of the existing calibration process, since there is no dedicated calibration device, most of them use a combination of simple tools such as plastic pipes and rulers to work. [0003] Taking the calibration of the boiler drum water level measurement system as an example, the safety of the boiler operation is related to the safety of the power grid and social electricity consumption. Controlling th...
