Submersible Robot

[releeps]

Hi all, really glad to find a forum commited to submarine hobby. Nice to meet you all.

I am currently involved in a project to construct a prototype submarine/submersible robot from scratch. Basic Stamp microprocessor will be used on the prototype. It involves two main parts]http://www.subcommittee.com/forum/icon_smile.gif[/img]

Simple if I understand your question correctly. Isolate the tube opening to the pressure sensor from water flowing over the hull shape as it moves. On our R/C models, we usually place the tube opening to the pressure sensor in the ADC-1 (auto depth control) inside the free flood hull in the bow as far forward as is practicable. As the sub dives deeper or rises, the bow part of the hull arrives at the preset depth first. This location inside the hull, while still exposed to the water is still isolated from the water flow outside moving over the hull. This way the sensor reads water pressure only whether hull is moving or not. Send us some pictures of your 'robot'.

Hi Steve,
Thanks for the fast

Hi Steve,
Thanks for the fast response. So that means that as long as the pressure sensor outlet or ADC outlet is not in the direct flow of water, there wouldnt be any effect?
My buoyancy tank's pressure sensor outlet is located in the direction of flow now but we had plans to fabricate a small cover to deflect the flow. The small cover will be open at the sides to allow the outlet to be still open to the water. But initially we were thinking if the difference in the high pressure in the outlet and the lower pressure just outside the cover will create any effect on the pressure.
Thanks again.
Sorry I don't have any pictures of the submersible in my home but will definitely post them next week.
Regards,
Aw.

Simple, expose to the water, but not the flow.
