Correct tank volume chart is key point for analysis of oil inventory, which is important in management for retail petroleum industry.

Due to the long term operation, the tank is possibly inclined or anamorphic. Then the tank volume will be not accurate. You need tank calibration system to recalibrate your tank to produce a new correct volume chart.

Work Principle

The volume measurement instrument (high flow dispenser) will measure the volume of oil product discharged from or into he tank. The probe will indicate the product level in the tank. Each product level correspond with a certain volume. Both data of volume and product level are collected by computer in real time, with intelligent data processing model, automatically create a tank volume chart.

Features

∗ High accuracy, the error is less than ±0.5%

∗ Advanced software creating the volume chart for tanks automatically, without need of manual operation

∗ Magnetostrictive probe with very high accuracy is specially designed for tank calibration

∗ High measuring speed (with High flow measurement dispenser), take less than 2 hours to measure an oil tank with 30 cubic meters

∗ The system automatically set height limit, preventing overflow in the process of calibration

∗ Two patterns working: Intermittent downtime working and continuous working

∗ The system is designed with protect data from losing function in case of outage

∗ For underground or above ground tanks
