Contrec 515 series with FP01 application measures the flow and consumption of petroleum fluid. The two-channel frequency flow input enables the instrument to calculate the “delta” net volume that is used by a consuming device.

Each channel has an analog temperature input that allows for volume correction to reference conditions. It is expected that the feed flow will be greater than the return flow. An exception will be raised if negative flow is detected.

The instrument can be used to measure a range of crude and refined petroleum fluids included gasolene, jet fuels, heating oils, diesels, lube oils and LPGs.


The volume total and flowrate are derived from accurately measured frequency and the number of received pulses.

volume = pulses/k-factor

volume flow = frequency/k-factor

consumption volume = feed – return

The volume correction calculations are based on the ASTM D1250-04 and API Table 54 standard for the following products:

Crude Oils
Lube Oils
Refined Products
Light Hydrocarbon Liquids (LPG)
Volume correction for other fluids can be calculated by the following means:

General Coefficient of Expansion
Reprogrammed User Table
