SEMTECH® HI‑FLOW 2 Calibration Kit

 

Sensors offers a kit for OOOOb required daily calibration and bi-annual calibration checks.

HI-FLOW 2 Calibration Kit

Requirements to perform the calibration and calibration checks:

  • Fully charged HI‑FLOW 2 analyzer with host software version 3.2
  • Sensors' calibration kit: (includes flowmeter assembly, 2 exhaust hoses, 1 calibration gas hose)
  • PC/tablet/phone for data control with Wi-Fi capabilities
  • Reference CH4 gas bottle with regulator for flow control in the concentration range of 2.5 to 4%
  • Ventilation hose
  • 9/16” wrench (supplied with HI‑FLOW 2)

Automated report generation:

HI‑FLOW 2 host software version 3.2.2 adds features to automate the data collection and report generation compliant with EPA NSPS subpart OOOOb Rule (referred to here as OOOOb). This software automation greatly simplifies the tasks for the user, which would otherwise require numerous data recordings and data averaging. This version also automates the bi-annual calibration audits required for OOOOb and generates corresponding reports. The reports are stored on the HI‑FLOW 2 for later retrieval whenever necessary.

Quick daily calibration

The calibration kit can be ready to use in just a few minutes. The software runs the daily calibration in about five minutes.

Clear, complete results

The reports generated include calibration data, graphs and pass/fail for the results.

Results can be viewed as data and graphs, as shown in the sample below.

Periodic simple audit checks as well as gas linearity checks can be easily completed on the unit with the included software scripts. In the example shown below “OOOOb Daily Audit”, a single reference gas bottle was used (4.047% methane) and the whole system was automatically checked under ambient zero conditions, no dilution, low dilution and high dilution against the 5% OOOOb requirement. Once set-up, this process takes around five minutes to complete. Test data can also be downloaded as a .csv or as a .pdf report.
