The operating conditions associated with the handling and processing of oils, gases, and fluids always place the highest demands on the measurement and control technology as well as the control systems. Extreme temperatures, highly viscous and abrasive substances, as well as the most diverse process environments, are just some of the demands placed on the control and operating technology of such extensive overall systems. HIT offers advanced solutions in the field of process technology for the oil & gas industry and can come up with innovative operating systems for overall control in flexible and dynamic refinery processes. For over 25 years, we have been leading the way nationally and internationally in process instrumentation in many areas of liquid and gas processing. As a manufacturer of the overall control and instrumentation technology for such systems, we are constantly setting new standards. Our work focuses on the automation and optimization of entire tank farms, fail-safe application and operation, as well as the control and measurement of fill levels, flow rates, and blending. In this way, we guarantee system processes that are as non-intrusive as possible, high system availability, and long-term profitability.
