An input device for controlling buoyancy includes a means to control a second rate. You may select the second rate by using the input means 81. This may also be known as a rate selection button. You can also select the second rate by selecting the first rate. Depending upon the circumstances, a buoyancy device may include many different features. In one embodiment, the buoyancy control device comprises a buoyancy tank and a weight belt.
Weight belts
Although the centre of buoyancy is out of the divers control, the suit weight and position of the cylinder can be adjusted by them. Weight belts and integrated BC weighs are also options that divers can use to control their buoyancy. These buoyancy control devices are best worn below the knees, at the waist and above the hips.
Dump valves
You can use a BCD to regulate your buoyancy in two different ways. You have two options to control your buoyancy: either you can deflate the entire bladder or you can add some air to the bladder. Dump valves attach to a string and control air levels. BCDs usually have one to two dump valves per shoulder. The dump valves are used to deflate the bladder during diving to maintain comfortable buoyancy.
Jacket-style buoyancy control device
A jacket-style buoyancy control device (BCD) is a good investment, regardless of whether you are a novice diver or an expert diver. BCDs come in many sizes and can be worn comfortably over swimsuits. Some models have front and rear weight pockets, while others have rear trim pockets. These pockets allow you to easily access your weights. A jacket-style BCD comes with a cushioned soft back. This makes it more comfortable to wear and lets you easily adjust its buoyancy.
BC attachment systems
A BC is a type scuba dive vest used by divers to maintain buoyancy and prevent sinking. A BC is used to secure the diver's SCUBA tank. BCDs may look similar, but their functions and design can vary from one model to the next. It is important that you know how to use your BC correctly, and have a backup plan in place for any malfunctions.
Pneumatic valves allow for the control of depth.
Pneumatic pumps are central to most industrial processes. They control fluid flow by using the force-balance principle. A pneumatic valve has three ports: an air supply, a control signal output, and an exhaust. A lever arm is positioned above the device that needs to be controlled. It is equipped with a flexible diaphragm that changes pressure when an external sensor varies its position. The supply air valve opens when the sensor pressure rises. The controlled device moves when the pressure is higher.
