APPENDIX A Meter Installation/Operation June 1985 Bulletin 1.2.11 Caution Read  Instructions  carefully  before  attempting to  operate.    Each  meter  Is  thoroughly  tested before  leaving  the  factory.    Smith  Meter  Inc. cannot  accept  claims  for  damage  occurring during the fire 24 hours of operation. Installation Instructions 1. The  meter  and  its  accessories  are  precision  instruments  and should be treated accordingly.  Prior to installation the equipment should    be    protected    from    adverse    weather    conditions    and accidental abuse. 2. The  installation  should  provide  protection  from  sand,  dust,  rain, sleet,    etc.,    where    extreme    adverse    weather    conditions    are encountered. 3. Except   for   vertical   meter   installations   the   meter   should   be mounted on a suitable base or platform so it will not be supported by the piping. a. Dimensional  outline  drawings  showing  size  and  location of anchor holes are available for all meters. 4. Install   the   meter   so   that   it   cannot   be   accidentally   drained   of product; however, it is advisable to drain the meter of water and sediment periodically. a. When installing a meter, be sure drain plug is accessible. 5. Piping should not produce an undue strain on the meter. 6. Protect   the   meter   and   system   against   the   effects   of   thermal expansion with a relief valve. 7. Where necessary, a deaerator or air eliminator should be installed to keep air and vapor out of the meter. 8. All piping should be internally cleaned before the meter is put into operation. a. Rust, dirt, welding shot, and other foreign material should be removed completely. b. Remove   the   inner   mechanism   and   flush   the   lines   to prevent damage to the metering element. c. The meter should be protected by a strainer. 9. Where   necessary,   a   flow   limiting   valve   should   be   installed downstream of the meter to protect it from excessive flow rates. 10. Remove  the  inner  mechanism  if  the  system  is  to  be  pressure tested with water or if debris is to be flushed from system. 11. Do not calibrate with water or allow water to stand in the meter. a. Flush  meter  with  a  light  lubricating  oil  if  it  is  left  idle  or stored. 12. Unless otherwise specified, meters normally flow from left to right when viewed from the flanged side of the housing. a. Most  meters  can  be  changed  to  flow  from  right  to  left. See the appropriate manual. 13. A counter may be located in any one of four 90° positions.  Large numeral counters may be located in any of eight 45° positions. Operation Instructions Start-Up It  is  best  to  fill  the  meter  by  gravity.    However,  where  hydraulic  conditions require  that  the  pump(s)  be  operated,  extreme  care  should  be  used  in opening the valves at the meter. In  all  instances,  the  air  should  be  evacuated  slowly  from  the  meter  and system. 1. Establish product flow through meter. a. With outlet valve closed, slowly open inlet valve. b. Slowly   open   outlet   valve   until   counter   begins   to   turn. Leave    outlet    valve    in    throttled    position    until    air    is evacuated from meter. This  is  necessary  to  protect  the  meter  from  excessive speed due to air in the lines of system. 2. Loosen   vent   plug   of   double   case   meters   (except   for   vertical meters) when meter is filled with liquid. a. Permit   the   air   trapped   in   the   meter   cover   to   escape through the threads.  Close plug when product begins to seep through threads. 3. Fully open inlet and outlet valves. a. Open valves slowly, pausing if register operation is rough. Continue opening when operation becomes smooth. 4. Inlet  and  outlet  valves  should  be  operated  slowly  to  avoid  line shock.  Abrupt closure can create forces in excess of normal line pressure.    This  could  result  in  damage  to  the  meter  and  other equipment. 5. Do not set a reset type counter when the meter is operating. 6. The ticket securing pin in a printer head must be in the down or locked position when the meter is operating. 7 Meters  equipped  with  G,  ATG,  AMR,  or  Dummy  calibrators  can be operated in either direction. 8. Calibration adjustment has been made at the factory for zero error at  maximum  nameplate  capacity  on  33  SSU  solvent.    Due  to variations   in   operating   conditions   it   is   recommended   that   the meter be calibrated and adjusted after installation. 9. Meter  calibration  is  accomplished  by  adjusting  the  calibrator  dial or  knobs.    Calibration  may  be  changed  in  increments  of  1/20  of 1%.  The adjustment is concealed under a cover on the calibrator adapter. 10. To  obtain  maximum  service  from  Smith  meters,  it  is  suggested that detailed records be maintained.  Data such as model, serial number,   operating   rate,   type   of   product,   meter   clearances, totalizer   readings   and   other   pertinent   information   should   be recorded.  Such information is an excellent guide in scheduling a preventive  maintenance  program.    Refer  to  manuals  for  meter maintenance.
