Some of our customers need to track fuel consumption, not just fuel flow. Think a feed line and a return line, where what actually got used is the difference between the two. The Contrec 515 FP02 Petroleum Consumption Flow Computer is built for that kind of delta net consumption measurement.
It reads two separate analogue flow inputs at once, one for feed and one for return, and each channel has its own temperature input so volume correction back to reference conditions is done per line, not as a single average. This correction follows ASTM D1250-04 and ASTM-IP-API Table 54, so it works across gasolines, jet fuels, heating oils, diesels, lube oils, LPG, and custom fluid blends.
In actual application, this sits out in the field more often than in a control room, so it comes in a weather-sealed IP65 housing with a backlit alphanumeric LCD. It also has isolated 4-20mA loop retransmission, dual RS-232/RS-485 Modbus RTU serial links, and an adjustable 8-24V DC excitation supply for the flowmeters.
Before we quote this, we would normally check your feed and return flowmeter signal types, the fuel or fluid being measured, and your line temperature range.
Hope this helps.
