Description

technical field [0001] The invention relates to a liquid level measurement system, in particular to an air blowing type liquid level remote measurement system. Background technique [0002] At present, the liquid level remote measurement system of domestic ships basically adopts an independent system design, that is, an independent liquid level remote measurement system composed of a liquid level sensor, a signal acquisition unit, a signal processing unit, and a display. With the expansion of the functions of the ship automation system, many engine room monitoring and alarm automation systems now have the functions of signal acquisition, signal processing and display. The functions of the two overlap and the equipment configuration is wasted, which increases the use cost of the equipment and causes Waste of equipment resources. Contents of the invention [0003] The purpose of the present invention is to provide an expandable and editable air-blowing liquid level telemetr...
