摘要： A dispensing system includes a first metering system including a first housing, a first metering rod at least partially disposed within the first housing, and a first assembly defining a first metering chamber and releasably connected to the first housing. The first metering rod linearly translates through the first metering chamber so as to dispense a discrete amount of a first material from the first metering chamber. The dispensing system also includes a second metering system including a second housing, a second metering rod at least partially disposed within the second housing, and a second assembly defining a second metering chamber and releasably connected to the second housing. The second metering rod linearly translates through the second metering chamber so as to dispense a discrete amount of a second material from the second metering chamber. The first metering system is releasably connected to the second metering system.

摘要： A method and a gas flow meter for measuring gas flow. A cylinder is supported in the flow meter with a horizontal orientation. A piston is disposed movably within the cylinder, the piston having a surface which forms a clearance seal with a surface of the cylinder. The piston may have a low-friction coating such as diamond-like carbon. A gas flow to be measured is received at a gas inlet, and directed to the cylinder so as to move the piston within the cylinder. The gas flow is directed by valves and conduits alternately to the two ends of the cylinder, for measuring the gas flow in both directions of the cylinder. From the detected movement of said piston electrical signals representative of the gas flow are generated.

摘要： A fluid meter (27) comprising a housing (28) defining at least one crankcase (29) and two cylinders (25, 26), a crankshaft (11) disposed in the crankcase (29), two pistons (3, 4) respectively mounted in the cylinders (25, 26) for reciprocal movement, a first connecting rod (12) connected to one of the pistons (3) and to the crankshaft (11) for rotating the crankshaft (11) in response to the movement of the one piston (3), and a second connecting rod (13) connected to the other piston (4) and to the crankshaft (11) for rotating the crankshaft (11) in response to the movement of the other piston (4), wherein the first and second connecting rods (12, 13) have yoke slots (16, 17) with a circumferential periphery (62) for receiving a crank pin (19) radially offset from the crankshaft (11). The fluid meter (27) is characterized in that the circumferential periphery (62) of each one of said yoke slots (16, 17) has at least one resilient portion (61) for allowing a play? between said crank pin (19) and said circumferential periphery (62) of said yoke slot (16, 17) at said at least one resilient portion (61). The invention further relates to a multiple fluid meter assembly (61) comprising at least two fluid meters (27) as defined above, and to a fuel dispensing unit comprising a fluid meter (27) or a multiple fluid meter (61) as defined above.
