Product Details
Introduction
Bi‑directional Communication Power Module‑L is used for the need to transmit reliable pulse data to surface in in challenging hostile mud environment. The system is tolerant to high density of solids and high LCM concentrations in the wellbore.
The pulser has a directly driven valve to achieve reliability and LCM tolerance. It maintains a constant pulse height through the entire flow range.
