INSTALLATION
AND APPLICATION
＃The
size of the meter is determined according to the flow rate
in the installation place.
＃The
meter should be installed horizontally with the counter
upward, the arrow direction on the meter casing must
coincide with the direction of the water flow.
＃The
location for installation shall be protected from the
affection of strong magnetic fields, or explosion to
sunshine, or frozen and long time submergence in water .
＃The
newly-installed pipe shall be flushed so as to maintain
neither sand, nor sediment in it before installation of
water meter.
＃For
accurate measurement, the tap high should be higher than the
meter.
＃The
meter should not be directly connected with pipe ,but with
coupling, gasket and nut. When dismantle meters, don't force
to twist them for fear of damaging the body.
＃After
a long time use, the impurities or rust in the pipe should
block the strainer or enter into the interior meter, which
cause inaccuracy of meter. it'd better to clean the strainer
per three years, and newly calibrate the meter. But not
dismantle by self.
