Fuel Flow Transmitter
A Fuel Flow Transmitter measures the rate of flow and converts this to an electrical signal to drive a meter or other equipment. In this Transmitter a turbine is used as the driving element in place of the conventional electric rotor. Turbine speed is controlled by a spring-operated valve, which allows some fuel to by-pass the turbine at high flow rates. This feature has improved transmitter reliability, significantly reduced transmitter size and weight, eliminated the need for an electrical power supply and, allied with improvements to the pulse pick-off, has allowed the transmitter harness to be reduced to three wires in an enveloping screen.
