Operation

Blokschema-diepgangThe draft measurement system from cumarine works according the controlled airbubbler principle. As the result of blowing air in a pipe until the measure point (draftmark) The outboard water pressure passed on to the start of the pipe. In this way it is possible to bridge 300 meter (whitout loss). The back pressure of the draft mark is measured in the measure cabinet. This is also the place where the compressed air is distributed over the measure points. The measure values and temperature are converted to Data for processing in the computer.

The computer collects the data en compensates with temperature in the cabinat to get a more accurate measurement. Then the data is clarifying displayed on the computer monitor. From the computer the clino value is send via the relaiscabinet to the clinometer lights mounted outside on the top of the wheel-house.
