The Tank Calibration System can set up tank volume table (relationship between volume and height)
Tank Calibration System
The underground storage tank in gas station is easily deformed or inclined due to improper installation or geological reasons, which make the volume chart not accurate. Therefore to recalibrate the tank volume table will be most important. Censtar develop this system to help the customers to get the accurate volume table to improve the operation management.
System consists of a Heavy Duty Fuel Dispensing Pump, Special Magnetostrictive Plus Probe, computer and other accessories.
The Tank Calibration System can set up tank volume table (relationship between volume and height) by collecting and calculating oil volume data through the Fuel Dispensing Pump in / out and the oil lever changing height measured by probe. In entire system, the function of fuel dispensing pump is to refuel in/ defuel out oil to carries on measurement, and the value real-time data transfer to your computer system. Probe function is to measure the changing height of the oil lever within the tank and send real-time altitude information to computer.
The computer system gather both real-time data, analyze and calculate through the PID auto-tuning algorithm that filters out invalid data caused by oil fluctuation and saving valid data stored in database.
In the practical application, during calibration it is very difficult to make the calibration tank to be empty to a degree of no oil at bottom or to make the tank to be full to a degree of reaching the top of tank, so the computer system must also consider these cases at bottom / top to make complete tank table.
When the operation is complete, we can print out tank table, the whole process is automatic, without human intervention.
Main technical parameters: 1) Measured height:3800mm at maximum 2) Differentiate ratio:0.01mm 3) Accuracy: ±0.1mm 4) Measure accuracy: <±0.25% 5) Ex-proof mark: Exd AT3 6) Measuring range: 100~300L/min 7) Power supply: 220V 50Hz; 380V 50Hz 8) Environment temperature: -25°c~+55°c 9) Relative humidity: 20~95RH 10) Working pressure: ≤0.5Mpa 11) Apply to: diesel, gasoline,kerosene
Advantages: 1) automatically generate volume table, without manual operation. 2) High accurate volume table produced, error less than 0.25%. 3) Fast measure speed, less than 2 hours if calibrating a tank 30CBM 4) Oil discharging or sucking, both ways to create volume table 5) Interval stop or non stop working ways. 6) Automatic measurement or manual data input, two ways to select. 7) high oil level limitation setting automatically to avoid overfill 8) Powerful data save mechanism, avoid data loss. 9) multi-scale volume chart available for creation 10) Data copy available to avoid loss 11) Volume table data available imported to WordExcel and Txt format 12) Chinese and English language for choice
