The BrewOps DO was designed to be the world's first portable, yet inline, dissolved oxygen monitoring solution. Using a best-in-class optical oxygen sensor with a CIP-capable calibrated sensing cap, the BrewOps DO delivers consistent, accurate performance in even the most challenging brewing applications.
Unlike traditional portable measurement devices, which:
- Waste product by diverting beer to a drain
- Provide only a single snapshot in time
The BrewOps DO sits inline, capturing the full picture of dissolved oxygen (DO) levels during:
- Tank-to-tank transfers
- Filtration processes
- Packaging operations
When paired with the BrewOps Edge Gateway, the BrewOps DO provides consistent, traceable historical data, giving brewers real-time insights into their operations.
Brewers worldwide rely on the BrewOps DO to:
- Catch seal leaks in their equipment before they impact product quality
- Track oxygenation of chilled wort to ensure optimal fermentation conditions
- Compare pre- and post-filtration oxygen levels to confirm separation equipment is not introducing excess DO
By eliminating the guesswork, the BrewOps DO empowers brewers to reduce dissolved oxygen pickup, improve shelf stability, and maintain product consistency.

The BrewOps DO sensor integrates seamlessly with the BrewOps App, allowing brewers to monitor dissolved oxygen (DO) levels in real time during tank transfers, filtration, and packaging. Follow the steps below to set up, start, and monitor a DO session.
- Open the BrewOps App and select the bright tank, fermenter, or packaging line you want to monitor.
- Tap the DO icon located in the upper middle above the equipment image.
- Do not use the Purge or Reverse Purge icons, as these are meant for the BrewOps Purge only.
- A list of available BrewOps DO sensors will appear. Select the sensor you plan to use.
- The sensor status bar will change as follows:
- Grey → Not connected
- Yellow → Connecting
- Green → Connected
- The sensor’s LED lights will blink blue when successfully connected.
- Tap Next to continue.
- Enter the Session Name
- Pro Tip: Include the brew name, batch number, and activity type for better tracking (e.g., Pil421 Transfer).
- Set the Session Duration (minimum: 5 minutes, maximum: 12 hours):
- Sampling Interval:
- Every 30 seconds for sessions between 5–15 minutes.
- Every 1 minute for sessions between 15–30 minutes.
- Every 2 minutes for sessions between 30–60 minutes.
- Every 5 minutes for sessions between 60 minutes–12 hours.
- Auto → Uses the built-in NTC thermistor for accurate temperature adjustments.
- Recommended for sessions longer than 30 minutes or when temperatures fluctuate.
- Manual → Enter the liquid temperature manually if it remains consistent.
Accurate DO measurements require absolute pressure input, as oxygen solubility depends on total gas pressure.
- For Tanks Open to Atmosphere → Enter atmospheric pressure only (no additional head pressure).
- For Transfers Between Tanks → Enter the destination tank’s total pressure (atmospheric pressure + head pressure).
- For Transfers to a Packaging Line:
- Open-Air Fillers → Use the source tank’s head pressure + atmospheric pressure.
- Counter-Pressure Fillers → Use the destination tank’s head pressure + atmospheric pressure.
Tap Start Activity to begin.
- Once the BrewOps DO sensor connects, a green "Success" pop-up will confirm the process has started.
- Remain near the sensor for 30 seconds to ensure successful settings upload.
- The icon above the equipment will change from grey → green, indicating the activity is running.
- To make changes, tap the DO icon and select Edit Activity to return to the Activity Settings screen.
- When the session is complete, tap the DO icon and select Stop Activity in the pop-up menu.
- The sensor status bar will change as follows:
- Orange → Stopping
- Yellow → Disconnecting
- Grey → Session ended
- A green "Success" pop-up will confirm the session has stopped.
- If the pop-up doesn’t appear, wait up to 30 seconds for the process to fully complete.
- The icon above the equipment will turn from green → grey, indicating the session has ended.
By following these steps, brewers can track DO levels with precision, reduce oxygen pickup, and maintain product consistency throughout brewing operations.
