Assignee: HALLIBURTON ENERGY SERVICES, INC.
Field: Measurement (Instruments)
Classification: CPC E  G | IPC E  G

Claim 11:
12. A well measurement system comprising:
a downhole tool, wherein the downhole tool comprises:
a first device;
a master module disposed on the first device, wherein the master module comprises a master transmitter and a master receiver;
a second device;
a module disposed on the second device, wherein the module comprises a transmitter and a receiver; and

an information handling system for:
transmitting a signal to the module,
changing the master module from a line driver controlled by the master transmitter to a line receiver controlled by the master receiver,
transmitting a return signal from the module to the master module
determining Tdd of a time for the signal to travel from the master module to the module, wherein the Tdd=(Counter-Tf-T4-T3)/2, wherein the Counter is a second time for the signal to travel from the master module to the module and back to the master module as measured by the master module, the T4 is a master module signal detection time, the Tf is a fixed time delay and the T3 is a module signal detection time,
determining T2, wherein the T2=T3+(Tdd-T1), wherein the T2 is a time delay and the T1 is a time it takes for the signal to be transmitted and detected at the master module,
receiving the return signal from the module with the master module, and
measuring a time for the signal to travel from the master module to the module and the return signal back to the master module.
