Real time Aanderaa current meter data collection system

155-156Aanderaa current meters are widely used for recording the current speed and such other 4 parameters by deploying them over extended period of time. Normally data are recorded on magnetic tape and after recovery of current meters, data are read in laboratory. In this paper a method is described to read the real time current meter data and display/print/store on cartridge. For this, binary coded electrical signal available at the top end plate of the current meter is connected by underwater cable running from the Aanderaa current meter deployed near the offshore platform to microprocessor board EC-85 interfaced to HP-85B personal computer housed in the platform cabin
