Data from the registration sensors is transmitted via the tool bus to the memory tool at the top of the chain. Data is stored in non-volatile flash memory chips under the control of a downhole processor. The tool is compatible with all standard CNPS memory tools and records readings from all sensors at a rate of up to 10 sets per second.
To power tool motors on the waterline or when the motor cannot be supplied from the surface.
