Fuel consumption measurement

Fuel consumption measurement:
Fuel consumption is measured in two ways:
(a) The fuel consumption of an engine is measured by determining the volume flow in a given time interval and multiplying it by the specific gravity of the fuel which should be measured occasionally to get an accurate value.
(b) Another method is to measure the time required for consumption of a given mass of fuel.
As already mentioned two basic types of fuel measurement methods are:
-Volumetric type
-Gravimetric type
Volumetric type flow meter includes Burette method, Automatic Burette flow meter and Turbine flow meter.
Gravimetric Fuel Flow Measurement
The efficiency of an engine is related to the kilograms of fuel which are consumed and not the number of litres. The method of measuring volume flow and then correcting it for specific gravity variations is quite inconvenient and inherently limited in accuracy. Instead if the weight of the fuel consumed is directly measured a great improvement in accuracy and cost can be obtained. There are three types of gravimetric type systems which are commercially available include Actual weighing of fuel consumed, Four Orifice Flow meter, etc.
