Ultrasonic Flow Meters & Switches

Ultrasonic flow meters are widely used in oil and gas exploration, refining, and pipelines; power generation and distribution facilities; mining operations for slurry and water monitoring; and construction projects requiring accurate fluid flow control. Their non-invasive design makes them adaptable across a broad range of industrial sectors.

Yes. Many ultrasonic flow meters feature clamp-on or inline designs using robust materials compatible with corrosive, high-pressure, or high-temperature fluids. For oil & gas and mining environments, models are available with appropriate hazardous-area ratings and material certifications. ESG can advise on the right specification for your application.

An ultrasonic flow meter provides continuous, real-time measurement of fluid flow rate and totalized volume. An ultrasonic flow switch is designed to detect whether flow is present or has exceeded a set threshold, triggering an alarm or control signal. Both use ultrasonic technology but serve different monitoring and control purposes.

Clamp-on ultrasonic flow meters require no pipe cutting, welding, or process shutdown — sensors are mounted externally on the pipe. Inline models require installation in the pipe section but offer higher accuracy. The choice depends on your installation constraints, accuracy requirements, and fluid characteristics. ESG provides guidance on the best fit.

Ultrasonic flow meters can measure a wide range of liquids including water, hydrocarbons, chemicals, and light slurries, as well as gases in some configurations. Transit-time designs work best with clean, homogeneous fluids, while Doppler models handle liquids containing suspended solids or gas bubbles, common in mining and wastewater applications.
