Odorant Injection Measurement

Odorant Injection Measurement

Telltale warnings can save lives. Safely using natural gas requires an effective odorization program. Consistently monitoring gas flow, computing and injecting the proper odorant dosage, and most importantly recording this activity are the basic process.  An odorant injection flow meter is a key component to this system.

Typically, state regulations dictate the minimum odorant concentration. Since these odorants (mercaptan organosulfurs being the most common) are expensive, economic concerns bound maximum dosing.

Common mercaptan doses are in the range of 2 – 4 ppm (by volume, to gas). This typically translates to 1 – 200 cc/minute, depending on pipeline size and natural gas velocity.

Robust flow monitoring equipment is essential to ensure proper odorization of natural gas. Low flow measurement, accuracy, repeatability and easily-integrated signals for SCADA systems and PLC’s are required.

The inherent capabilities of Max Precision Flow Meters make us an industry standard for odorant measurement by local distribution companies and citygate sites.



Max Precision Flow Meters are the leading choice for odorant injection measurement:

  • P213
    • K-Factor:  1000 pulses/cc
    • Flow Rate: 0.5 cc/min – 1800 cc/min
  • P214
    • K-Factor:  90 pulses/cc
    • Flow Rate: 5 cc/min – 10,000 cc/min


  • Drift free accuracy for decades of service
  • Accuracy not affected by start/stop flow
