Page 11: Meter Operation
Component Technical Manual MA26 MP-T1 Meter for Fuel Dispensers 1.1.6 METER OPERATION The fuel enters the meter via the intake orifice (5) and flows up to the valve (3), where it applies pressure to the piston (7), while the piston (6) linked to the former by the connecting rod (8) is in communication with the exhaust orifice via the opening (4) of the rotary valve (3). -
Page 12: Mp-T1 Pulser
This device will be placed in series with the nozzle of a dispenser. It converts the fuel flow into rotations of a shaft. One rotation of the MA26 volume meter represents a fuel flow of 70cl. The MP-T1 housing is placed on top of the volume meter. This housing contains the MP-T1 electronics (placed on a support), 3 gear wheels and a magnetic disc. - Page 13 Component Technical Manual MA26 MP-T1 Meter for Fuel Dispensers Magnetic disk The disc contains one outer ring, divided into 20 north and 20 south polarised magnetic parts and one inner ring divided into 10 north and 10 south polarised magnetic parts. The disc will be driven by, as mentioned before, the volume meter.
