Accuracy, Safety & Reliability

Tanker truck-mounted Lease Automated Custody Transfer (LACT) units are currently the best method to transfer the ownership of crude oil from the production lease to transportation.
With many interests involved, it is critical that your operation rely on accurate, safe, and reliable measurement, despite challenges of changing operating parameters and conditions, operations in remote locations, and harsh environments.
