1 PURPOSE / DESCRIPTION
1.1 MA26 Piston Meter
1.1.1 PURPOSE
The MA26 meter has been designed to provide accurate measurement of
traditional fuels using a positive displacement system.
1.1.2 DESCRIPTION
The meter is made up of a body containing four sleeved cylinders which in turn
contain four pistons. These pistons move in connection with two transmission
rods. Rollers connected to a crankshaft move within the groove of these rods.
The alternative linear motion of the pistons therefore results in a rotary crankshaft
movement.
A valve is driven by the crankshaft, successively putting the cylinders in
communication with the meter inlet and outlet. The valve glides between a
slide plate integrated to the body and a gasket fixed to the outlet collector. The
slide plate has four holes, which are connected to the four cylinders. The link
between the gasket and the outlet collector is made via a Teflon diaphragm,
which acts as a seal between intake and exhaust.
The upper section of the crankshaft drives the indicating device.
