LIQUID MEASURMENT SERVICES
Flow Meter Surface Treatment for Oil and Gas Measurement Equipment
SPL Measurement Services applies AcuFlow, a nanoscale omniphobic surface treatment, to flow meters and related measurement equipment as part of scheduled calibration, proving, and pull-and-clean service events. The result is longer service intervals, reduced cleaning labor, and equipment that stays cleaner between every visit.
The Problem: Fouling Degrades Measurement Integrity Before Anyone Notices
Hydrocarbon deposits do not announce themselves. Paraffin accumulates gradually inside Coriolis meter tubes. Asphaltenes precipitate during pressure drops and adhere to turbine internals. Crude oil residue coats the PTFE liners and electrodes of magnetic flow meters, pulling line balance out of tolerance before the next scheduled service date.
By the time fouling is visible, the measurement error it caused has already compounded across days or weeks of production data. Custody transfer accuracy is compromised. Cleaning events that should have been planned become urgent. Equipment that should last years gets abraded by repeated aggressive cleaning into a shorter replacement cycle.
The root cause is not the fluid. It is the adhesion energy of untreated metal surfaces.
The SPL Solution: AcuFlow Surface Treatment Delivered During Your Existing Service Events
SPL applies AcuFlow, a nanoscale surface modification treatment, to the wetted interior surfaces of flow meters and measurement equipment during scheduled calibration, proving, and pull-and-clean service events.
AcuFlow modifies metal at the molecular level, bonding at 2 to 4 nanometers thick. It creates an omniphobic barrier that is simultaneously oil-repellent and water-repellent, resisting the adhesion of:
- Paraffin and paraffin wax deposits
- Asphaltenes and crude oil residue
- Inorganic scaling including barium sulfate and calcium carbonate
- Produced water organic films
At 2 to 4 nanometers, AcuFlow is optically clear, dimensionally neutral, and has no effect on calibration, meter performance, or measurement accuracy. It has been tested and documented on precision custody transfer equipment in active upstream and midstream field environments.
No separate mobilization. No additional downtime. No new vendor to coordinate. AcuFlow is applied by the same SPL technician performing your calibration or proving work, during the same service event you already have scheduled.
Compatible Equipment
AcuFlow is applicable to any wetted metal surface in your measurement program that regularly accumulates deposits:
– Coriolis flow meters
– Magnetic flow meters, steel and PTFE liner

Documented Field Results
AcuFlow performance in flow measurement applications is supported by documented field outcomes, not laboratory projections.
Eagle Ford Shale, Coriolis Flow Meters, High-Paraffin Crude Application
A major upstream operator running Coriolis meters with a combined capacity of 80,000 BOPD faced extreme paraffin buildup driven by stabilized crude with limited capacity to keep paraffin in solution. Untreated meters required cleaning every few weeks. Following AcuFlow treatment, those same meters ran for 18 months without a single cleaning event while maintaining accurate crude flow rate readings. The operator subsequently ordered treatment for the remainder of their Coriolis meter fleet across all Eagle Ford assets. Documented savings: $6,500 per eliminated cleaning event.
Eagle Ford, Karnes County, Magnetic Flow Meters, Produced Water Application
A produced water disposal operator running 103 magnetic meters across a gathering network was cleaning each meter every seven days to maintain line balance within a plus or minus two percent tolerance. Following AcuFlow treatment, line balance held below one percent for 75-day windows. Over a projected six-month period, the treatment eliminated an estimated 1,150 cleaning events, reduced process downtime by 1,570 hours, and generated $80,000 in projected cost savings.
Summary of Documented Performance Outcomes
– $6,500 saved per eliminated Coriolis cleaning event
– $80,000 projected 6-month savings across 103 mag meters
– 1,150 cleaning events eliminated in 6 months
– 1,570 downtime hours reduced
– 18 months continuous operation without cleaning on treated Coriolis meters
– Line balance maintained below 1% tolerance for 75-day windows
How AcuFlow Fits Into Your Measurement Program
AcuFlow is not a replacement for calibration, proving, or data validation. Those services remain the foundation of a defensible measurement program. What AcuFlow does is extend the performance window between service events and reduce the labor intensity of cleaning when service does occur.
The optimal integration point is during any service event where equipment is already pulled or accessible: a scheduled proving run, a pull-and-clean, a calibration visit, or a meter repair. SPL field technicians handle the application as part of that event.
SPL Measurement delivers the full range of services that surround AcuFlow. Meter calibration and proving including custody transfer proving, allocation proving, master proving, and pull-and-clean proving with advanced data analytics. Gas measurement services including SCADA setup, system design, custom HMI programming, portable GC analysis, H2S testing, and True Vapor Pressure testing.
Liquid measurement services including custody transfer proving, liquid sample collection and analysis, and pressure and temperature device verification. Production allocation through SurePhase, SPL’s proprietary allocation platform. Data validation and audit services backed by multiple levels of human review. Automation services including SCADA integration, PLC programming, and HMI development.

Frequently Asked Questions About AcuFlow Nanotechnology
Does AcuFlow affect meter calibration or measurement accuracy?
No. AcuFlow is 2 to 4 nanometers thick, optically clear, and dimensionally neutral. It does not interfere with calibration factors, Coriolis tube vibration frequency, magnetic field measurement, or turbine rotation. Multiple field deployments on custody transfer meters confirm that treated meters maintain their calibration history without adjustment.
What flow meter types are compatible with AcuFlow?
AcuFlow is compatible with Coriolis flow meters, magnetic flow meters, turbine meters, guided wave radar level transmitters, optical sensors, and stainless steel meter runs and flow spools. Compatible base materials include stainless steel, carbon steel, aluminum, brass, copper, titanium, PEEK, PTFE, nylon, quartz, and borosilicate glass.
How is AcuFlow applied and how long does application take?
AcuFlow is applied by an SPL field technician during a scheduled service event including calibration, proving, or pull-and-clean. No vacuum chambers, lengthy cure times, or specialized equipment are required. Application to a single meter adds a small increment of time to an existing service event rather than requiring a separate visit.
How long does AcuFlow last?
AcuFlow is designed for durability in high-flow, high-Reynolds number environments and has been tested to withstand temperatures up to 250 degrees Celsius. Field applications on Coriolis meters have demonstrated continuous performance for 18 months. Longevity varies based on process conditions, fluid chemistry, and cleaning practices. SPL can discuss expected performance windows based on your specific application during a service consultation.
Does AcuFlow eliminate the need for meter cleaning entirely?
No. AcuFlow slows the rate of deposit accumulation and reduces the adhesion strength of deposits that do form, extending the window between cleaning events and reducing cleaning labor when service occurs. It does not permanently prevent all fouling under all conditions. In some applications, cleaning intervals have been extended by months. In others, the primary benefit is reduced labor and faster turnaround during planned cleaning events.
What causes paraffin and asphaltene fouling in flow meters?
Paraffin fouling occurs when stabilized crude with reduced light-end content loses capacity to keep paraffin in solution, allowing crystallization and adhesion to untreated metal surfaces. Asphaltenes precipitate during pressure drops, temperature changes, or when crude blends with different solubility parameters are mixed. Both deposit types adhere because untreated metal has high surface energy that is favorable to hydrocarbon adhesion.
Which oil and gas basins does SPL Measurement serve?
SPL provides field measurement services across the Permian Basin, Eagle Ford Shale, Bakken, DJ Basin, Appalachian Basin, Gulf Coast, and other producing regions. SPL operates 40+ locations with embedded field technicians across key upstream and midstream producing areas in the United States.
