Contrec 515-PP01 Flow Computer

The 515 PP01 measures the flow of a pressurised petroleum fluid according to ASTM D1250-04. The frequency flow inputs can accept a quadrature signal for ISO 6551 level B pulse security. An analog pressure, temperature and/or density input allows for volume correction to reference conditions..

This instrument is compatible with a wide range of flowmeter frequency outputs, including millivolt signals, reed switches, Namur proximity switches and pulse trains via its smart front-panel program selection.

The flow computer displays the net and gross flowrates, resettable and accumulated totals. It can be used to measure a range of crude and refined petroleum fluids included gasolene, jet fuels, heating oils, diesels and lube oils.

CALCULATIONS

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

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
