Why We Recommend HI-FLOW 2 For Voluntary QMRV Projects

September 9, 2024
By: David Booker, CTO, Sensors Inc.

What is the HI‑FLOW 2?

The HI‑FLOW 2 is a high-volume sampler used primarily in Quantification, Monitoring, Reporting, and Verification (QMRV) projects to:

• Accurately quantify fugitive methane emissions from various sources
• Monitor emission levels over time
• Report findings to stakeholders
• Verify the effectiveness of emission reduction measures

Why do we recommend the HI‑FLOW 2?

We recommend the use of the HI‑FLOW 2 sampler to ensure compliance with regulatory standards and support voluntary reduction initiatives. It also provides reliable data for decision-making and reporting purposes.

Here are some other key reasons we recommend the HI‑FLOW 2 for QMRV projects:

High-precision methane quantification

The HI‑FLOW 2 can conduct high-precision sampling from 0.0005 CFM to 25 CFM (0.015 to 700 lpm). This is the widest dynamic range available on the market.

Regulatory compliance

The HI‑FLOW 2 meets or exceeds all accuracy, linearity, and cross-interference requirements listed in 40 CFR 60 Subpart OOOOb. It meets OSHA Class 1 Division 2 classification for hazardous locations as well.

A lower detection limit of less than 1 ppm

The HI‑FLOW 2 uses state-of-the-art Tunable Diode Laser Absorption Spectroscopy (TDLAS) to accurately and consistently measure methane-specific concentrations of less than 1 ppm. It can also measure and account for methane background concentrations.

Other features of the HI‑FLOW 2:

• Portable design for ease of use in various field conditions
• Real-time data processing and analysis capabilities
• Built-in scripts for automated calibrations, leak measurements, testing protocols, and report generation
• Customizable scripts for additional regulations or applications
• Robust data logging and storage for long-term monitoring projects

What are unique features or innovations in HI‑FLOW 2 compared to other similar technologies as it relates to QMRV projects?

The HI‑FLOW 2 is the only device that offers TDLAS technology, which is by far the best technology on the market for measuring methane-specific concentrations. This is because of its:

• Accuracy and linearity from sub-ppm levels to percent levels
• Lower detection limit
• Minimizing cross-interferences from other gases
• Stability (negligible zero and span drift)

In addition, HI‑FLOW 2 can provide accurate measurements on the widest range of leak sizes available, from very small leaks to very large leaks. HI‑FLOW 2’s software also comes with features that can better contextualize the data collected. For example, the sampler’s geofencing capability allows users to document exactly where measurements are made, which can ultimately improve the quality and detail of the final report.

What are the primary benefits of using HI‑FLOW 2 in voluntary QMRV projects?

• Accurate Emission Quantification: HI‑FLOW 2 provides precise measurements essential for effective emission management.
• Compliance Support: HI‑FLOW 2 ensures adherence to regulatory requirements and supports voluntary emission reduction commitments.
• Cost-Effective Monitoring: HI‑FLOW 2 reduces the need for repeated site visits through reliable, consistent data collection.
• Enhanced Data Integrity: HI‑FLOW 2 minimizes errors and enhances the reliability of collected data for reporting and verification.

How does HI‑FLOW 2 improve the accuracy and reliability of data in QMRV projects?

The HI‑FLOW 2 sampler improves accuracy through its advanced methane-specific sensor technology and real-time data processing capabilities, ensuring that emissions are quantified with high precision. The robust design of HI‑FLOW 2 minimizes operational errors and environmental interferences, while the sampler’s comprehensive data logging ensures that all relevant data is captured and stored for analysis and verification.

What are the steps involved in implementing HI‑FLOW 2 in a QMRV project?

1. Initial Assessment: Evaluate the specific needs of the QMRV project to ensure the HI‑FLOW 2 sampler is the best-suited technology for the project and that all the project’s unique needs are being met.
2. System Setup: Deploy the HI‑FLOW 2 units at the identified emission sources.
3. Calibration: Perform pre- and post- test audits, periodic calibration checks, and necessary recalibrations to ensure that the data collected is the most accurate it can be.

• Data Collection: Collect data to ensure consistent monitoring per the project requirements.
• Data Analysis: Use the system’s real-time analytics to interpret the collected data.
• Reporting and Verification: Compile reports based on the collected data and verify the accuracy of the findings.

How user-friendly is the HI‑FLOW 2 system for project managers and field operators?

The HI‑FLOW 2 is designed with a user-friendly interface that simplifies operation for both project managers and field operators. Its intuitive controls, clear display, and straightforward data management system reduce the learning curve and make it accessible for users with varying levels of technical expertise.

What kind of ROI can organizations using HI‑FLOW 2 expect?

Organizations using HI‑FLOW 2 can expect a significant return on investment (ROI) due to the system’s accuracy and efficiency. By reducing the frequency of site visits and minimizing errors, the HI‑FLOW 2 lowers operational costs. Additionally, its robust data collection capabilities enhance compliance with environmental regulations, potentially avoiding fines and improving the organization’s reputation for sustainability. The long-term savings and enhanced decision-making capabilities contribute to a strong ROI.
