ABSTRACT:
A volumetric fuel meter is included in a fuel system whereby the measurement is compensated to express fuel flow in units of weight such as pounds, grams or in units of energy such as BTU's or calories (grams). The meter measurement is associated with an automatic compensator which compensates the measurement for variations in the gravity of the fuel. Temperature and pressure sensing devices are associated with the measuring systems. Two separate measuring systems are employed for engine fuel systems which return unburned fuel from the injector. One system employs a single volumetric meter with a bubble remover or cooler while the second system employs two volumetric meters. The present measuring system has embodiments that provide for mechanical compensation and electrical measurement and subsequent compensation of the gravity of the fuel.
