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.

Retest due-date engine, condemnation workflow, hot-repair records and testing-station documentation aligned to the Gas Cylinders Rules, 2016.
Learn More →Truck Load-out & Gate Control
Portal reads at the loading bay and gate reconcile every cylinder against the invoice, e-way bill and vehicle before the truck is released.
Learn More →Distributor & Dealer Network
Godown stock, security-deposit position, cylinder liability and refill performance for every distributor, dealer and franchise in the network.
Learn More →Industrial & Specialty Gas
Oxygen, nitrogen, argon, acetylene, CO₂, helium and gas-mixture fleets — batch and analysis-certificate linkage, valve type, purity grade and test class.
Learn More →Rental, Demurrage & Billing
Automatic day-count from the last movement event, slab-based rental, holding charges and dispute-proof statements per customer account.
Learn More →Control Tower & AI Analytics
Turn-around time, dwell, loss-rate and demand forecasting across plants and regions — with exception alerts pushed to the people who can act.
Learn More →What Is Captured Per Cylinder
Every cylinder carries a complete, queryable record — from the day it is enrolled to the day it is condemned and scrapped.

Control Tower & AI AnalyticsHow 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.
