GENERALThe UltraSonic Flowmeter (USF) is used to measure the internal leakageof the green, blue and yellow hydraulic systems. The USF is only usedon ground.The Transmitter and the leakage transducer are the main components ofthe USF.The USF transmitter has on its front panel:- a keypad,- a display,- three indication LEDs,- a connection port for the leakage transducer.The leakage transducer has:- two transducer measuring heads to measure the flow rate,- a temperature probe to measure the hydraulic fluid temperature,- a transducer cable to be connected to the transmitter,- a fly nut for the attachment to the hydraulic pipe,- a fastening chain with a protection tube and a chain clamp to safety theleakage transducer during the leakage measurement procedure.
