Precision bulk liquid instrumentation, continuous inventory reconciliation, and intelligent hardware edge integration with the EQUPRO-VFD system for compliance under the Tanzania Revenue Authority (TRA).
Request Engineering ConsultationWe deliver industrial-grade telemetry solutions covering sensor installation, console configuration, localized interface translation, and hardware-secured tax data piping.
We deploy high-accuracy magnetostrictive probes within underground storage tanks (USTs) and aboveground storage tanks (ASTs). These systems utilize physical wave propagation principles to achieve ±0.1mm height repeatability, providing real-time product volume tracking.
Fuels expand and contract dynamically with temperature changes. Our engineered setups compile inputs from multi-point RTD temperature sensors embedded along the probe, applying ASTM D1250 tables to calculate gross-to-net volume correction directly at 15°C (59°F).
Continuous density monitoring ensures absolute fuel quality control by identifying product fuel contamination. The secondary water float detects liquid-liquid boundary layers, alerting managers of underground tank condensation or moisture ingress before it hits dispensers.
Fuel zones require absolute explosion protection. Our engineers install ATEX, IECEx, and TBS compliant galvanic isolation barriers (Ex-ia) and flameproof conduits (Ex-d), safeguarding raw telemetry signals from sparking risks in Hazardous Zone 0, 1, and 2 environments.
We configure and poll leading industrial ATG controllers (including Veeder-Root TLS series, OPW SiteSentinel, and Hectronic) using RS-485 serial Modbus RTU, proprietary active protocols, and TCP/IP Ethernet linking physical probes with modern local networks.
By connecting console fuel volumes to dispensing flow meters, the system performs Automated Stock Reconciliation (ASR). It alerts operators of delivery discrepancies, tank leaks, or fuel pilferage immediately by tracking continuous volume variances.
Under the Tanzania Revenue Authority (TRA) regulations, bulk liquid operations and petroleum retailers must fiscalize their sales and reconcile inventory in real time. We bridge physical fuel depots with federal digital compliance servers through a robust, tamper-proof edge gateway architecture.
The magnetostrictive probes poll product height, water interface, temperature, and net volume, routing metrics directly to the physical ATG console controller at microsecond intervals.
The EQUPRO-VFD edge gateway queries the console via Modbus RTU or TCP/IP. It acts as the local controller, compiling tank volumes alongside fuel dispenser sale pulses.
The EQUPRO-VFD signs each transaction payload, encrypts the dataset into a secure JSON schema, and transmits the compliance telemetry over a redundant GSM/GPRS or fiber pipeline straight to the TRA virtual fiscal servers.
This integrated engineering approach eliminates discrepancy audits by supplying TRA with verified, digitally signed volumetric inventory readings. Every fuel delivery, stock drawdown, and dispenser transaction is tracked, compiled, and reported automatically—slashing administrative compliance overhead and mitigating manual accounting discrepancies.
