Scope of this manual
SCOPE OF THIS MANUAL
This manual contains information concerning the installation, operation and maintenance of Badger oscillating piston meters.
To ensure proper performance of the meters covered, the instructions given in this manual should be thoroughly understood.
Retain the manual in a readily accessible location for future reference.
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.

Unpacking and Inspection
To avoid damage in transit, Badger oscillating piston meters are shipped to the customer in a special shipping container.
Upon receipt of the meter, perform the following unpacking and inspection procedures. If damage to the shipping container
is evident upon receipt of the meter, request the carrier to be present when the meter is unpacked.
1. Carefully open the shipping container following any instructions that may be marked on the container. Remove all
cushioning material surrounding the meter and carefully lift meter from container. Retain the container and all packing
material for possible use in reshipment or storage.
2. Visually inspect the meter for any physical damage such as scratches, loose or broken parts, or any other sign of damage
that may have occurred during shipment.
OTE:N If damage is found, request an inspection by the carrier's agent within 48 hours of delivery. Then file a claim with the
carrier. A claim for equipment damaged in transit is the responsibility of the customer.
Installation
The procedure covering the installation of a standard oscillating piston meter are essentially the same regardless of the meter
model being installed or the configuration involved. Before attempting the installation, read the instructions given in the
following paragraphs to become familiar with the requirements and procedures involved. Any special instructions required
for the installation and/or electrical connection of accessory equipment such as registers, pulse transmitters, remote batch
controllers, etc., will be provided as a supplement to the manual.
Preliminary Considerations
Factors to consider before proceeding with installation:
1. Avoid locating the meter in close quarters. The area in which the meter is to be installed should provide adequate space to
permit cleaning and maintenance.
2. Verify that the operating temperature range of the meter is compatible with the temperature range of the uid or uids to
be metered.
THE METER MUST BE OPERATED WITHIN ITS RATED TEMPERATURE RANGE TO OBTAIN OPTIMUM ACCURACY AND
PREVENT DAMAGE TO THE METER PISTON.
3. Ensure that the ow range of the meter agrees with the ow rate or rates to be used in metering the uid.
THE LIFE OF THE METER MAY BE SERIOUSLY IMPAIRED IF OPERATED AT FLOW RATES ABOVE THOSE SPECIFIED.
4. If solid material is present in the uid to be metered, it may be necessary to install a strainer in the facility piping ahead
of the meter. In metering applications involving slurries, the nely divided, undissolved solids must be maintained as a
suspension in the liquid. Oscillating piston meters are positive displacement type meters and may not operate properly
with liquids containing solid particles unless the above precautions are observed.
5. In metering applications involving abrasive materials, slurries, or liquids that may leave a residue or buildup of deposits, a
meter by-pass and ushing system should be incorporated into the facility piping installation to permit periodic clean-out
of the meter. Figure 2 illustrates a typical meter installation incorporating a bypass and ushing system.
