Smart CO₂ Inventory Monitoring: Proactive Refill Planning for Industrial Sites in Taiwan

S09 wireless transmitters connect to the CO₂ tank's existing level and pressure sensors, making inventory visible in real time so refill planning can start well before a tank runs low, cutting late-night dispatch.

Project Profile

• Region: Taiwan
• Category: Industrial
• Products: S09

Reference Impact

• Real-Time — Tank level and pressure visibility (Inventory awareness)
• Proactive Refill — Low-level alerts replace urgent dispatch (Smoother scheduling)
• Est. 35% — Fewer emergency refill dispatches (Estimated improvement)

Case Snapshot

A call for an emergency CO₂ delivery at midnight is not good news for any gas supplier or the production line waiting on it. At one industrial site in Taiwan, refill requests were often raised only once tank levels were already low, often turning into night-time dispatch. Without replacing the existing level and pressure sensors, an S09 wireless transmitter now sends tank data over NB-IoT to a central platform, letting refill planning start before risk builds up.

Problem

Refill Requests Waited Until Tanks Ran Dry

Factories that depend on a steady CO₂ supply struggle to spot a declining inventory trend early when tank status is tracked through manual checks, phone reports, or field experience alone. When a refill request only goes out once a tank is nearly empty, suppliers and site teams are left arranging urgent dispatch, sometimes overnight.

If a refill genuinely does not arrive in time, a CO₂-dependent line can be forced to slow down or stop, and every minute spent waiting on supply is lost capacity. That kind of gap rarely shows up on a production schedule until it happens, leaving the floor to react on the fly.

Solution

Existing Level Sensors Gain a Remote View

An S09 industrial wireless transmitter connects directly to the site's existing CO₂ tank level and pressure sensors, sending data over NB-IoT to a central monitoring platform. Operators can check level and pressure remotely instead of relying solely on manual rounds.

The setup deliberately leaves the existing sensing hardware untouched, adding only a wireless transmission layer on top of it, which keeps the rollout quick and low-risk. As inventory approaches the refill threshold, the team can schedule delivery, coordinate routes, and confirm site conditions earlier — refill planning no longer waits for the last moment.

Value

Dispatch Moves From Midnight to the Calendar

Dispatchers no longer get pulled out of bed by a midnight call — inventory trends show up on the platform ahead of time, so refill planning happens calmly during the day, and the need for emergency requests and last-minute dispatch drops noticeably.

No one has to answer a midnight call anymore — the inventory speaks up first.

Next Step

Provide the existing level- and pressure-sensor models and interfaces to check whether the current instruments can remain in place with a wireless communications layer added on top.
