Description
Badger oscillating piston meters are positive displacement type meters intended for use in fluid metering applications
involving chemical solutions or food ingredients The meters are available in a variety of size and configurations that cover
a wide range of flow rates and special applications The design of the meters incorporates a magnetic drive system that
minimizes the number of parts in contact with the fluid being metered A removable housing cover provides easy access to
the internal components of a meter for cleaning and/or maintenance
The basic components of an oscillating piston meter (see
Figure 1 ) consists of a precision-machined housing, piston, magnet
assembly, control roller and housing cover In operation, the piston functions as the measuring element As fluid flows
through the meter, it causes the piston to oscillate within a measuring chamber in the meter housing Each oscillation of the
piston is proportional to a specific volume of fluid The specific volume measured varies with the size of the meter The larger
the meter, the larger the volume of fluid measured for each oscillation of the piston The circular oscillations of the piston are
magnetically coupled through the wall of the measuring chamber to a follower magnet or an electromagnetic pickup which
in turn operates a meter-mounted accessory such as a register or pulse transmitter
