Eesiflo

What Eesiflo does

Eesiflo Technologies Inc. is a privately held, family-owned industrial instrumentation manufacturer founded in 1983 (originally as EES) and headquartered in Rayville, Louisiana. The company designs and manufactures capacitance-based inline sensors for measuring water content in crude oil, refined fuels, lubrication oils, and hydraulic fluids, alongside ultrasonic transit-time flow meters. Its core product platforms are the EASZ-1 (2-wire loop-powered water-cut probe) and EASZ-2 (online water-in-oil monitor), supplemented by the EASZ-2 Full Range (FR) full-cut meter that measures 0-100% water content using wide-range oscillator technology, and the Sonalok 7SZ (wall-mounted) and Portalok 7S (portable) ultrasonic flow meters. Products carry CE/EMC compliance, Ex-rated hazardous-area certifications, and support 4-20mA, Modbus, HART, RS-232, and Bluetooth interfaces for integration with industrial control systems.

Eesiflo sells primarily to oil and gas operators (upstream wellheads, production separators, LACT units, custody transfer skids, pipeline corrosion monitoring), with secondary applications in marine engineering and shipping (main engine lubrication, fuel purifiers), power generation (turbine lubrication), heavy manufacturing and industrial hydraulics, and mining. The go-to-market is sales-led with enterprise field sales through four wholly-owned regional offices in the USA, Singapore, Czech Republic, and the UK, augmented by a network of international contractors, resellers, and agents serving 140+ countries. Revenue derives from capital equipment sales (EASZ-1, EASZ-2, FR, ultrasonic flow meters) with perpetual licensing, supplementary technical support and spare parts, and a USA-based flow meter rental service with rent-to-own options.

The company is self-financed with no institutional investors, operates with 11-50 employees, and maintains wholly-owned regional entities for global distribution. Leadership passed from founder David Michael Hughes to sibling Phillip Hughes in 2023. The EESIFLO trademark was formally registered in 2023, and the company continues to evolve its EASZ platform, most recently with Bluetooth-enabled wireless calibration and the FR full-range variant.
