AVL FuelSystem PLU general overview

Feature AVL FuelSystem PLU Customer Benefit

Measurement Range 0.05 … 300 l/h Suitable from smaller up to larger engines

Sensor resolution 11600 @ 0,05 – 20 [l/h]

3400 @ 0,13 – 75 [l/h]

1700 @ 0,35 – 150 [l/h]

840 @ 0,8 – 300 [l/h]

Smaller measurement error in the lower measurement

range.

Bubble sensor Yes

Response time < 125 ms Capable to measure in fast dynamic conditions

Fuel Temperature

Conditioning Range

10 … 70 °C Allows operation of engine operation at different

temperature

Temperature Stability < 0.1 °C Higher repeatability

Functional check Temperature and pressure control,

plausibility check

Reduce wrong measurement

Functional check: a quick overview

• Functional check of PLU sensor

• Functional check of pressure regulator and pump

• Proves the functional stability of the conditioning loop


Functional check: plausibility of PLU sensor

PLU121PUMP ON

VENTING ON

Check done on 2 different flow settings


Functional check: pump, pressure regulator and conditioning circuit

VENTING OFF

Check done on 3 different flow settings


Operating panel

S1: Power On/Off

S2: Switch between manual and remote operation

S3-S6 only work if S2 is on manual, if S2 is on

remote, then operation only via DUI/Ethernet or CAN

S3: Switch on inlet pump

S4: Switch on outlet pump

S5: Venting

S6: Automatic fuel change (option)
