About Energoflow AG
Energoflow AG is an ISO 9001 certified Swiss company based in Olten, specialising in the design, engineering and manufacture of flow measurement solutions based on modern ultrasonic technology. The product range includes ultrasonic flow meters of the LF and GF series for liquids and gases, custom metering stations and instrumentation skids, as well as calibration and proving rigs for gas and liquid meters in various configurations (critical nozzles, reference meters, gravimetric method, high-pressure versions, container modules). In addition, the company offers hot-tapping services, engineering services for process automation and instrumentation, and techno-commercial consultancy covering everything from product development and project management to certification and compliance. The skid modules are delivered including installation, commissioning and training of the customer's personnel. Customer industries include oil and gas (custody transfer), water and wastewater supply, power plants, chemicals and gas distribution networks; deliveries are made worldwide.
