Specialized mounting, vibration-isolation, and zeroing steps add another USD 3,000-5,000 to commissioning. Lifecycle economics favor premium meters, but procurement teams often concentrate on upfront budgets. Subscription-based meter-as-a-service offerings are emerging to convert capital expense into operating expense and accelerate adoption.

Cyber-Security Exposure Of Wireless Smart Meters

Hard-coded credentials and unencrypted firmware channels have triggered multiple advisories. CISA’s 2025 alert listed 14 vulnerable models across six vendors. Ransomware altered flow data at a European water utility, forcing a 48-hour boil-water order and highlighting the stakes for public health. ISA/IEC 62443 now mandates encrypted communication, secure boot and role-based access controls, yet only 31% of installed meters meet the standard. Vendors responded by embedding hardware security modules; Schneider Electric added TPM 2.0 and WireguardVPN support at an incremental USD 800 per device.

Segment Analysis

By Technology: Precision Requirements Drive Mass-Flow Adoption

Mass-based methods accounted for USD 2.6 billion in 2025 and are advancing at a 7.4% CAGR. The flow meters market benefits as hydrogen blending and carbon-capture sequestration demand direct mass measurement immune to density shifts. Coriolis meters have become the default choice for liquefied CO₂ custody transfer, illustrated by the Northern Lights CCS project in Norway, which operates at 100 bar with ±0.05% uncertainty. Ultrasonic designs are displacing turbines in gas distribution because they keep ±1.5% accuracy when hydrogen reaches 20% of volume.

Volumetric technologies still hold 28.9% of 2025 revenue, anchored by electromagnetic meters in municipal water networks. Differential-pressure orifice plates remain common in steam lines, though they require 10-20 diameters of straight pipe. Thermal mass sensors are flourishing in biogas and compressed-air loops, where low flow rates compromise turbine performance. Positive-displacement units persist in fuel-dispensing and viscous-liquid batching. Vortex meters offer a mid-price, low-maintenance option for power-plant steam. Collectively, these trends underscore a structural rotation inside the flow meters industry toward high-accuracy, self-diagnosing devices that integrate seamlessly with digital-twin software.

By Mounting/Installation: Non-Invasive Retrofits Gain Momentum

In-line hardware represented 48.2% of 2025 revenue but is growing at a slower 4.2% pace because brownfield sites face downtime penalties if pipes are cut. Clamp-on variants, by contrast, are expanding at 5.9% and permit installation without depressurization. A North American midstream operator retrofitted 120 lines in eight weeks using clamp-on ultrasonic devices at 62% lower cost than in-line alternatives. Insertion probes, which penetrate but do not replace pipe sections, are finding niches in large-diameter water mains.

Battery innovations extend field life to 10-15 years, letting meters act as wireless IoT nodes. Functional-safety certification for Safety Integrity Level 2 has widened the addressable market to nuclear and pharmaceutical plants. Still, custody-transfer points continue to rely on in-line meters that deliver ±0.1% certainty. The flow meters market now segments by tolerance as much as by mechanics, with end users balancing cost, accuracy and downtime avoidance.

By Fluid Type: Gas Metering Accelerates With Hydrogen And LNG

Liquid applications generated 65.6% of 2025 revenue, yet gas metering is growing faster at 6.2% through 2031. Germany’s hydrogen-blend rule compels replacement of 2.3 million turbine meters with ultrasonic models by 2028. The Netherlands’ HyWay27 will install more than 300 ultrasonic meters to track pure hydrogen flows at distribution pressure. LNG export terminals are deploying multipath ultrasonics to maintain ±0.15% accuracy from -162 °C to +50 °C.

Steam metering also shows momentum as district-heating operators move from orifice plates to vortex sensors, reducing pressure drop and maintenance. On the liquid side, pharmaceuticals are adopting single-use Coriolis meters that eliminate cleaning validation, while food processors choose hygienic electromagnetic units for clean-in-place cycles. The flow meters market therefore spans temperature extremes from cryogenic LNG to boiling steam, highlighting the breadth of technological requirements.
