Acoustic Flow Meter Tool - AFM

AFMThe Patented Acoustic Flow Meter Tool – AFM is a high temperature downhole tool designed to measure fluid velocity and fluid density in an oilfield production operation incorporating an ultrasonic device. AFM includes continuous temperature measurement for logging and correlation purposes. Memory and SRO operations are included. AFM incorporates high precision electronics and measures accurately flow in a wide range of fluid velocity. The AFM connects to our Fast Hybrid Telemtry Tool (FHT) for Real Time Data Transmission.
