Detection method of buoy liquid level transmitter

Abstract

A detection method of a buoy liquid level transmitter comprises a detection device, wherein the detection device displays basic data pictures, basic data are input according to fields displayed in the basic data pictures, the detection device performs computation according to the input basic data, and a standard value is formed by the data obtained after computation and displayed on the detection device; then a measured display value is obtained by the detection device through the buoy liquid level transmitter of an instrument, the display value and the standard value are further analyzed, data are recorded, whether the instrument is qualified or unqualified is displayed according to an allowable error range obtained through analysis, and a result is displayed on the detection device; finally, a calibration curve graph measured by the instrument is drawn according to the result of the recorded data and displayed on the detection device.

Description

technical field [0001] The invention relates to a buoy corrector, in particular to a detection method for detecting the correction record of the liquid level of the buoy. Background technique [0002] It is known that the current pharmaceutical, semiconductor or chemical and petrochemical plants are all equipped with many storage tanks, and these tanks are used to load chemicals or other liquids. After erection of these tank tanks, a buoy liquid level transmitter will be installed on the tank tank. The buoy liquid level transmitter can measure the liquid level in the tank tank and the interface of two kinds of liquids with different specific gravity, and transmit the corresponding 4~ The 20mA signal is used to detect whether the liquid level in the installed tank meets the regulations. [0003] When testing the cylinder tank, pour liquid with a single specific gravity into the cylinder tank, and when the liquid flows into the float level transmitter, the float level transmi...

Problems solved by technology

[0004] Usually, there are many problems in the artificial judgment method, because when the data of the cylinder tank measured by the buoy liquid level transmitter has an error with the data stipulated by the original cylinder tank qualification, the inspector will judge by himself that the data in the error range is not much different, usually It will be deemed that the displacer liquid level transmitter meets the regulations, and the detection method of recording data will be completed. However, this detection method is easy to cause the detector to cheat others, and it is also an irresponsible detection behavior.
