The F127 flow computer has been developed to calculate corrected differential liquid volume at normal conditions. This is calculated by measuring the uncorrected volumetric flow and actual line temperature in both the supply and return line. These signals are processed with the thermal expansion coefficient algorithm stored in the flow computer. The reference temperature can be defined as desired (e.g. 15°C, 20°C or 60°F). The usual difficulties encountered in such applications include: pulsating flows, very low consumption readings, vibration and high ambient temperatures. These are all well catered for in the design and operation of the F127.
The display shows the compensated consumption/flow rate, total, accumulated total and actual line temperatures. On-screen engineering units like Nm³ are easily configured from a comprehensive selection.
