SERVICING PARTS AND ASSEMBLIES
When the performance of a Turbo meter indicates a need for
servicing, refer to the following instructions pertaining to removal,
inspection and installation of service parts and assemblies Also
see the Recordall Turbo Series Meter Parts List for part numbers
of replaceable components and correct ordering information If
satisfactory repair cannot be made, contact Badger Meter
Removing the Meter Head
Recordall Turbo Series meters can be serviced without removing
them from the line A typical installation would be equipped with
drain and piping valves To inspect or replace components of
the head assembly, close the upstream and downstream valves
However, if the installation does not have a drain valve, proceed
as follows to relieve pressure:
UPSTREAM AND DOWNSTREAM VALVES MUST BE CLOSED
BEFORE ATTEMPTING TO REMOVE METER HEAD FROM
HOUSING. FAILURE TO DO SO CAN LEAD TO THE HEAD BEING
"EJECTED" FROM HOUSING, CAUSING PERSONAL INJURY
AND/OR PROPERTY DAMAGE!
1 Loosen each of the head bolts about 1-1/2 turns Do not
completely remove the bolts
2 If the O-ring between the meter head and the housing
is secure and not leaking, pry the measuring element
assembly loose by inserting a screwdriver blade where the
head and housing join together
BE SURE THAT ANY WATER COMING OUT OF THE METER HEAD
DOES NOT SPRAY ONTO ELECTRICAL EQUIPMENT AND CREATE
A SHOCK HAZARD.
3 Allow the meter to drain and relieve internal pressure
4 When pressure is relieved, remove the head bolts Lift the
measuring element assembly from the housing
Removing the Local Register or Encoder
The Recordall Turbo Series meter registers and encoders are easily
removable to facilitate in-line service
1 Remove the register lid and shroud by removing the seal
screw
2 Remove the shroud by rotating the register assembly
counterclockwise until it stops This provides clearance so
it can be lifted off the measuring element assembly See
Figure 3 and Figure 4
To reinstall the register, follow the above procedure in
reverse order
