Ultrasonic flow meters deliver high-accuracy volumetric flow measurement without introducing obstruction, wear surfaces, or pressure loss into the process line. For industrial systems prioritizing reliability, maintenance reduction, and lifecycle performance, ultrasonic technology provides a robust alternative to mechanical and differential pressure-based metering. BPC offers a full range of ultrasonic flow meters engineered for industrial environments.
At BPC, ultrasonic flow meters are applied within broader flow control architectures—integrated alongside valve bodies, automated actuators, and system instrumentation—to improve process stability, verification, and energy efficiency. For application-specific requirements, both the VF-7 Series valve bodies and VF-9 Series valve bodies are commonly evaluated within system design.
Ultrasonic flow meters measure fluid velocity by transmitting and receiving high-frequency sound waves through the flowing medium. The most common industrial method is transit-time measurement, a principle also utilized in precision devices such as the Atrato flow meter.
Two ultrasonic transducers are positioned diagonally across the pipe:
Flow rate is calculated using:
This measurement method introduces:
For closed-loop systems where pump efficiency, valve performance, and flow stability are critical, this is a significant operational advantage.
Ultrasonic flow meters are ideal for clean or lightly contaminated liquids across industrial environments.
Within an integrated flow control system, ultrasonic meters provide real-time flow verification upstream or downstream of control valves, automated butterfly valves, pump skids, and heat exchangers. When paired with system instrumentation such as displays and instruments, they improve diagnostics, balancing, and predictive maintenance planning.
Because there is no flow obstruction, ultrasonic meters do not contribute to pressure drop. This supports:
Modern industrial ultrasonic flow meters deliver:
This makes them well-suited for energy accountability and process validation. In applications where multiple technologies are evaluated, ultrasonic meters are often compared against turbine flow meters and oval gear flow meters depending on system requirements.
With no moving mechanical components:
Maintenance intervals are significantly reduced compared to mechanical flow technologies.
Material selection is driven by chemical compatibility, pressure class, and environmental exposure.
Ingress protection ratings (IP65, IP67, or higher) ensure reliability in washdown or outdoor installations.
Proper installation ensures measurement stability and accuracy.
Key requirements include:
Unlike insertion or turbine meters, ultrasonic meters do not require internal penetration into the flow path, reducing leak risk and simplifying commissioning.
In a complete industrial system, technology selection must align with process conditions.
Ultrasonic:
Best for clean liquids, low pressure loss systems
Not ideal for heavy slurry or high aeration
Turbine
Best for clean liquids with stable flow
Moving parts subject to wear
Magnetic
Best for conductive fluids
Not suitable for hydrocarbons
Mechanical
Best for cost-sensitive applications
Pressure drop and maintenance
Ultrasonic flow meters are often selected when energy efficiency, long-term reliability, and low lifecycle cost are primary design drivers.
Ultrasonic flow meters are not standalone devices—they are performance verification tools within a broader control architecture.
When integrated with:
They enable:
This system-level integration aligns with BPC’s position as a comprehensive industrial flow control partner—not a single-product supplier.
Ultrasonic technology should be specified when the application requires:
For slurry, abrasive, or high solids content processes, alternative technologies may be more appropriate, including options such as oval gear flow meters or turbine flow meters.
Selecting the correct flow measurement technology requires evaluation of:
BPC supports system-level evaluation to ensure the selected ultrasonic flow meter aligns with overall process reliability objectives.
If you are designing or upgrading a process system and require integrated valve and flow measurement solutions, BPC provides the engineering support and product depth across ultrasonic flow meters, instrumentation, and full valve body configurations to support long-term performance.

Titan’s inline ultrasonic flow meters, now featuring ASCII streaming, mark a significant leap forward in flow measurement technology. Utilizing our patented ‘time-of-flight’ ultrasonic technology, these meters deliver exceptional accuracy across a broad range of liquid flow rates.
Our journey to develop a high-precision, non-invasive ultrasonic flow meter began in 2001 as part of a strategic initiative to create the world’s leading small-bore flow meter. In collaboration with the renowned Cranfield Institute of Technology, Titan’s R&D team pioneered a patented ultrasonic technology that has since evolved into the Atrato range—versatile flow meters designed to meet diverse OEM challenges.
By integrating specialized algorithms and advanced techniques, Titan has introduced a new generation of ultrasonic flow meters that excel in low-flow conditions while providing precise, reliable measurements across various industrial applications.
Titan’s proprietary interface software comes standard with all our software-configurable flow devices—the Atrato, Metraflow, and Pulsite Link—on a USB stick and is also available for download here. Legacy software versions can be accessed through Titan’s Legacy Software.
Powered by Titan Enterprises’ advanced embedded signal processing software, our devices deliver precise measurements for both viscous and non-viscous liquids. With a simple USB connection, users can link their laptop PC to multiple devices, monitor flow rate and total flow, and adjust various operating parameters as needed.
The latest software interface version enhances both the instrument’s internal software and the PC interface, offering greater versatility and advanced operational features. This streamlined platform enables seamless integration into user processes or systems while providing improved diagnostic capabilities.
