Monitoring an 8-metre, 300,000-litre fuel tank
How one of Mongolia’s largest metallurgical plants replaced dipsticks and supplier paperwork with measured fuel in, fuel out and fuel in stock.
A top-100 Mongolian enterprise
Founded in 1994, the plant runs its own ore quarries and processing and produces steel and cast iron — billets, rebar and castings — as well as recycling scrap metal. It has long ranked among the country’s top 100 enterprises.
- 30 years in operation
- 1,500 employees
- 100,000 tons of steel a year
Supplier paperwork and a dipstick
Excavators, bulldozers, dump trucks and loaders refuel from vertical tanks in dedicated hangars — each 8 m tall, 7 m in diameter, 300,000 litres, with one pipeline for filling and one for dispensing.
Deliveries were taken from supplier documents and levels measured by dipstick; actual volumes in and out weren’t measured, leaving room for undetected drains and fraud. The plant wanted live tank level, measured receipts and dispensing, theft prevention and reports for any period.
Level, flow in and flow out on one bus
A DUT-E CAN fuel level sensor was extended to 8 metres with 1-metre add-on sections — easy to transport and install. DFM Industrial CAN flow meters on the fill and dispense lines measure every litre in and out. Everything connects through the S6 telematics interface.
A MasterCAN Display shows live fuel data to the operator handling receipts and dispensing, and a CANUp gateway sends it to a cloud platform with reports for economists, accounting and management.
The plant now sees current level and every volume filled and dispensed, in real time and in reports for any period. Fuel accounting for the tank is accurate and the risk of theft has been eliminated. Installation on the plant’s other tanks is being planned.
Task → Solution → Result
Paper-based fuel accounting
8 m, 300,000 L tanks tracked by dipstick and supplier documents.
DUT-E 8 m + DFM Industrial + display + cloud
Level plus measured inflow and outflow, shown on site and in the cloud.
Accurate accounting
Every litre in and out recorded; theft risk eliminated.
The fuel level sensor can be extended using 1-meter sections, which allowed us to quickly assemble and install it. The S6 cabling system made it easy to mount and quickly configure the entire fuel monitoring system.
