APPENDIX A METER CLEARANCE GUIDE CLEARANCE GUIDE The  clearances  listed  herein  should  be  used  as  a  guide  in  determining  whether  or  not  components  need  to  be repaired or replaced.  Also, they should be considered as average.  This means for instance, that if a nominal clearance is  .004,  for  manufacturing  tolerances  a  spread  from  .003  to  .005  is  permissible.    Because  of  this,  it  is  possible  when checking  with  feeler  gauges,  to  find  at  one  point  .003  clearance,  while  at  another  point  along  the  same  surface,  the clearance may be .005 or even .006.  However, from a performance standpoint, that portion which is .003 will generally cancel out the effect of the .005 or .006 ant average out at the nominal .004 desired.  At  no point should a clearance exceed 50% of the listed maximum. From this it should be clear that a part need not be replaced or repaired just because clearances at some point may slightly exceed the listed maximum. The ability of the meter to obtain acceptable repeatability and linearity for the particular operating conditions, such as  flow  rate,  viscosity,  lubricity,  abrasive  contaminants,  and  intermittent  or  continuous  duty,  should  be  considered  a better guide rather than clearances alone. For viscosities above 1000 SSU and/or temperatures above 150°  F., consult the factory. BLADE TO HOUSING CLEIRINCE With the Blade held toward the Housing, these clearances should be maintained between the Measuring Chamber and the full length of the edge of the Blade. ROTOR TO BLOCK CLEARANCE These clearances between Rotor and Block should be maintained the full length of the Rotor.
