In 1983, EES was incorporated by Mr. David Michael Hughes who was an eminently qualified metallurgist/chemical engineer, a true pioneer and protagonist for many diversified measurement and control products originating from the USA and UK that are now utilized across the world.

His primary interest in water in oil technology began in the early 70’s when he innovatively embarked on the introduction of early generation ‘pressure based’ oil in water, and water in oil percentage monitoring devices, and further pioneered their utilization in the oilfields of West Texas.

Two decades ago, EESIFLO International was established to enhance the design of, and to exclusively manufacture it’s proprietary range of water in oil monitors for the global oil and gas Industries, which has from it’s early generation(s) evolved into the industry standard EASZ-2 unit, and more recently the innovative FR series utilizing temporal frequency technology enhancing clarity and accuracy.
