摘要

The report describes a simple acoustical telemetering system that employs an electronic counter constructed in our laboratory. When the counter is coupled with an appropriately equipped sensor, an acoustical telemeter, and a standard receiver, the system can be used for remote monitoring of current meters, dredges, bottom water samplers, and other devices. Substantial savings of ship time are effected by its use. The counter unit is compact, light, and small enough to fit into standard pressure housings. It is reliable and accurate and is capable of about 7 days of sustained operation with the present rechargeable power pack. (Author)
