LPG & Industrial Gas Cylinder Tracking System
LPG & Industrial Gas Cylinder Tracking System
SeekSoft™ CTMS gives every cylinder a permanent digital identity — tracked from the filling carousel to the customer's shop floor and back, with statutory test status, custody and rental position visible in real time.
A cylinder tracking system gives each LPG, industrial, specialty or medical gas cylinder a unique, machine-readable identity — usually an on-metal UHF RFID tag, a laser-etched serial and a QR code — and then records every event in that cylinder's life: filling, quality checks, dispatch, delivery, customer custody, return, inspection, statutory retest and finally condemnation. Instead of a register that says how many cylinders should exist, the operator gets a live, auditable record of where each individual cylinder is, who holds it, whether it is legally fit to fill, and what it is earning.
Problems We Solve
What large-scale cylinder operations actually struggle with — across bottling plants, dealer networks, industrial gas depots and hospital supply chains.
SeekSoft CTMS Modules
One platform for the whole cylinder lifecycle — identity, filling, logistics, custody, compliance and money. Deploy the full suite or start with a single module.
Gas Cylinder RFID Tagging and Identity
Each cylinder gets one record linking its on-metal UHF RFID tag, NFC, QR code and stamped serial, and the tag survives shot-blasting and repainting. Readers pick up cylinders 2-5 metres away through steel racks, a full pallet or truck reads in one pass, and locked, encrypted tags can't be cloned onto grey-market cylinders.
Learn More →Bottling Plant and Carousel Automation
Each cylinder is identified at every station: pre-fill screening, the filling carousel, check-scale, leak test and valve and O-ring checks, all interlocked with your plant PLC over OPC-UA or Modbus TCP. Retest-due, condemned and foreign cylinders are stopped before filling, and weight, tare and test results are recorded against each serial.
Learn More →Cylinder Retesting and PESO Compliance
A retest engine forecasts which cylinders fall due in the next 30, 60 and 90 days by plant, dealer and region, and pulls due cylinders aside at gate-in. Testing-station dockets, certificates, re-stamp dates and tare-weight checks are held against each serial, so registers under the Gas Cylinders Rules, 2016 are ready whenever an inspector asks.
Learn More →Truck Load-out and Gate Control
RFID portals at the loading bay read 300 or more cylinders on a truck in one pass and check them against the invoice, e-way bill and vehicle. The gate barrier stays down until the load and the paperwork match, ANPR and driver ID are stamped on the same record, and empty returns are read in without manual challans.
Learn More →Distributor and Dealer Cylinder Management
See godown stock, security deposits, cylinder liability and refill performance for every distributor, dealer and franchise. Delivery staff use an Android app that scans offline, confirms each handover with an OTP and geo-tagged photo, and records the empty collected, while domestic cylinders delivered to commercial addresses are flagged.
Learn More →Industrial and Specialty Gas Cylinder Tracking
For oxygen, nitrogen, argon, acetylene, CO2, helium and gas mixtures, each cylinder carries its gas type, purity grade, valve outlet and test class, and despatch is blocked if they don't match the order. Certificates of analysis are linked to the fill batch, hospital cylinders are tracked down to ward and ICU, and dewar hold time is recorded per vessel.
Learn More →Cylinder Rental, Demurrage and Billing
Rental and demurrage are counted automatically from each cylinder's last movement, on slab rates you set, and customer statements list every serial so disputes close in one call. Deposits are compared with cylinders actually held, idle cylinders get a daily recovery list, and billing syncs with SAP S/4HANA, Oracle, Dynamics 365 or Tally.
Learn More →Cylinder Control Tower and AI Analytics
Turnaround time, dwell, losses and refill demand across plants and regions on one screen, with dashboards for plant, compliance, finance and leadership. Exceptions go by SMS, email, WhatsApp or app to the person who can act, demand is forecast by area, season and customer type, and customers with a history of non-return get a risk score.

How It Works
Six stages that repeat for the life of every cylinder — each one a scan, not a register entry.
Tag and enrol
Each cylinder is tagged, weighed, photographed and enrolled with its make, capacity, tare weight, valve and last test date. Existing fleets are converted in planned batches.
Screen and fill
At the plant the cylinder is screened against its retest date and condition before the carousel engages, and the check-scale weight is written against the serial.
Load and gate out
Load and gate out
Deliver and confirm
The delivery team scans on handover; the customer confirms by OTP; the empty is scanned back in the same transaction. Custody transfers with evidence attached.
Return and inspect
Empties are read back at the plant, inspected for dents and corrosion, and either returned to the fill pool, routed to hot repair or segregated for statutory testing.
Reconcile and act
Overnight reconciliation compares physical reads with ERP stock and dealer statements, and the exception list reaches the people who can close each line the next morning.
Choosing the Identification Technology
There is no single right answer. The correct choice depends on read volume, environment and how the fleet is handled — most operators end up running two layers.
| Technology | Read Range | Line of Sight | Bulk Read | Survives Blasting & Repaint | Relative Cost | Best Suited To |
|---|---|---|---|---|---|---|
| Printed barcode label | Contact to 0.3 m | Required | No | No | Lowest | Low-volume depots, short-life pilots |
| Laser-etched serial + QR | Contact to 0.5 m | Required | No | Yes | Low | Permanent fallback ID; customer and field self-scan |
| NFC tag | Up to ~50 mm | Near contact | No | Yes | Medium | Hospital wards, customer audits, smartphone-only teams |
| LF RFID (125 kHz) | 50–150 mm | Not needed | No | Yes | Medium | Legacy installed base; tolerant of metal and moisture |
| UHF RFID, on-metal (860–960 MHz) | 2–5 m typical | Not needed | Yes — full pallet or truck | Yes | Higher | Bottling plants, bay portals, gates, high-throughput fleets |
In practice, high-throughput LPG and industrial gas operations run on-metal UHF for hands-free plant and gate reads, with a laser-etched serial and QR as the permanent fallback that any phone can read. SeekSoft CTMS treats all of these as read paths into the same cylinder record, so a fleet can migrate technology without losing history.
Business Impact
What changes for the plant head, the compliance officer, the distribution head and the CFO. Ranges below reflect outcomes typically seen in comparable cylinder-tracking deployments; actual results depend on fleet size, baseline discipline and rollout scope.
Lower untraced losses
Cylinders that previously disappeared into "shrinkage" become a named holder, a last-seen location and a recovery action.
Retest compliance
No cylinder past its statutory test date can be filled, because the fill line is interlocked with the due-date engine.
Extra rotations per cylinder, per year
Idle cylinders are identified and recovered instead of resting at customer premises, which directly raises fleet productivity.
Faster recall and investigation
A suspect batch is traced forward to every cylinder that shared it, and backward to the shift, scale and operator that filled it.
Less reconciliation effort
Month-end stock reconciliation becomes a review of a short, aged variance list rather than a week of counting and calling.
Billing and deposits
Rental, demurrage and deposit positions are backed by serial-level evidence, which shortens collection cycles and settles disputes on the first call.
Who Runs Cylinder Tracking
The economics work differently in each segment, but the failure mode is the same — assets that leave the gate and stop being visible.
LPG bottling plants
Oil marketing company plants and private bottlers running carousels, check-scales and high-volume despatch with statutory obligations on every fill.
LPG distributors & dealers
Distribution networks holding large cylinder floats against security deposits, with daily doorstep delivery and empty collection to account for.
Industrial gas companies
Oxygen, nitrogen, argon, acetylene and mixture fleets rented to customers, where rental leakage and idle assets are the main financial exposure.
Hospitals & medical gas suppliers
Medical oxygen and nitrous oxide fleets needing ward-level custody, manifold bank visibility and audit-ready batch traceability.
Manufacturing & EPC sites
Large plants and project sites consuming cylinders across contractors, where site-level custody decides who pays for a cylinder that never comes back.
Exporters & multi-country fleets
Operators moving cylinders across borders who need ownership, test class and country-specific marking recorded against each asset.
