The flowcomputer Model F127 has been
developed to calculate corrected differential
liquid volume at normal conditions for generic
products. A typical application is the measurement
of fuel consumption by engines for power
generators, e.g. on board ships and locomotives.
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 corrected volumetric flow in each line is
calculated using the thermal expansion
coefficient algorithm stored in the flowcomputer.
The reference temperature can be defined as
desired, e.g. 15°C, 20°C or 60°F
