1) Manufacturer‘s specification, valid for the reference conditions as specified under reference conditions. Do not use this value for
the design.
2) For burners and engines or motors, the fuel oil meter must be selected on the basis of the permanent flow rate. For higher
viscosities, or if the meter is installed on the suction side, the pressure drop and any reduction in the measuring range must be
taken into consideration.
3) Weight without couplings.
