Read a cryogenic liquid cylinder chart as a history of stock change, then align it with fills, shifts and the production schedule. This supports reserve planning, but a falling level alone does not establish exact process consumption or explain its cause.
Confirm the vessel and the time context
Begin with the physical vessel identifier, gas and current site. Confirm that the chart belongs to the cylinder being discussed, especially after an exchange. Check the latest reporting time before treating the last visible reading as the current stock position.
CryoFor TM2 replaces the electronic gauge head on a liquid cylinder with a compatible capacitive level probe. Readings pass through a 2.4 GHz Wi-Fi router to the cloud. Staff can review level history, fill markers and a run-out forecast in the web console or through the Telegram bot and MiniApp.
Match chart changes with real events
Put the production calendar and fill records beside the chart. Mark shift starts, extra work, quieter periods and vessel exchanges in your operating notes. Use fill markers as reference points and confirm them against the actual supply record before comparing one cycle with another.
| Chart observation | Context to check | Useful first question |
|---|---|---|
| Steeper decline during a shift | Output, working hours and changed activities | Was the workload different? |
| Level rise near a delivery | Fill or exchange record and vessel identity | Does the event match the right cylinder? |
| Decline during a quiet period | Actual operation and natural losses | What conditions differed from comparable periods? |
| Interrupted reporting | Latest reading time and offline alerts | Has monitoring been restored? |
| Different weekly pattern | Shift mix, fills and production schedule | Are the periods genuinely comparable? |
Ask practical questions every day
A daily review should connect the latest stock position to the next decision. Is the expected reserve sufficient for the planned work until replenishment? Has an extra shift or a moved delivery changed that assessment? Does a low-level alert need action from the designated person?
Review the forecast alongside those facts. If the chart appears unusual, first check vessel identity, recent fills and data freshness. During a reporting interruption, use the site’s agreed local checking procedure rather than extending an old trend as though it were a new reading.
Use weekly reviews before changing supply
Compare cycles with similar vessel models, gases, working hours and production conditions. Include total observed stock decline, including natural losses, when considering how long the reserve lasts. Keep units consistent; the same level percentage on different vessels need not represent the same available quantity.
Before changing delivery frequency or the working reserve, check several comparable cycles and discuss the proposed change with the people responsible for production and ordering. Record the decision and review its effect afterward. Separate a measured change in the chart from an explanation that still needs checking.
FAQ: Does a falling level prove a leak?
No. Stock can decline through process demand and natural losses, while interpretation also depends on the operating record and monitoring context. A level trend does not diagnose a leak. Refer unusual observations to the responsible site team using established procedures.
FAQ: Can the chart replace consumption or billing records?
No. Level history supports operational planning; it is not a billing measurement or an exact allocation of gas to a shift or product. Use the appropriate measurement and production records for those purposes and investigate differences before changing assumptions.
