Non-Intrusive Ultrasonic (FLEXIM)

A Flexim clamp-on ultrasonic flow meter measures the flow of liquids, gases, or steam using externally mounted ultrasonic sensors. Because the sensors are installed on the outside of the pipe, there is no need to cut into the process line or interrupt operations. Flexim technology provides accurate, non-intrusive flow measurement for a wide range of industrial applications.

Flexim ultrasonic flow meters use transit-time technology to measure the difference in travel time of ultrasonic signals moving with and against the flow. This allows the system to calculate flow velocity and volumetric flow without any wetted components inside the pipe.

Clamp-on flow measurement offers several benefits:

• No process shutdown required
• No pipe cutting or hot work
• No pressure loss or obstruction
• Reduced installation costs
• Minimal maintenance requirements
• Improved safety for hazardous processes

Because the sensors remain outside the pipe, flow measurement can often be added without impacting production.

Yes. Flexim ultrasonic flow meters are designed to measure liquids, gases, and steam across a wide range of industries. Applications include water, hydrocarbons, natural gas, hydrogen, chemical processing, flare gas, energy management systems, and utility monitoring.

In most applications, no process shutdown is required. Flexim clamp-on sensors are mounted externally to the pipe, allowing installation while the process remains in operation. This helps facilities avoid costly production interruptions and outage planning.

Unlike inline flow meters, Flexim clamp-on ultrasonic flow meters do not contact the process fluid. This eliminates concerns about pressure drop, sensor fouling, corrosion, wear, and maintenance associated with many intrusive technologies. Installation can also be significantly faster and less disruptive.

Yes. Selected Flexim flow meter models are available with approvals for use in hazardous industrial environments, making them suitable for many oil and gas, petrochemical, and energy applications.

Yes. Spartan Controls offers Flexim flow meter rental options for customers who need temporary flow measurement, troubleshooting, process verification, short-term projects, or proof-of-concept testing. Renting a Flexim meter allows you to gather accurate flow data before committing to a permanent installation.

A Flexim rental is ideal when you need to:

• Verify existing flow measurements
• Troubleshoot process issues
• Conduct a flow audit
• Validate pump performance
• Collect data for engineering studies
• Support turnaround planning
• Bridge the gap while waiting for a permanent flow meter delivery

Portable clamp-on ultrasonic flow meters can be installed without cutting into piping or interrupting operations, making them an effective tool for temporary measurement projects.
