2. OPERATING CONDITIONS
To maintain the stated high accuracy and long service life of FLOW MATE (OVAL M -
Ⅲ
), make sure
that the flowrate, pressure, temperature and viscosity are held within the ratings. The operating
conditions appear in the GENERAL SPECIFICATIONS on page 15. Conrm these ratings before
commencing operation.
Bypass Loop
Strainer
Valve
Short Pipe
Flow Direction
NOTE: Making measure-
ment with Size 38 meter
is acceptable only in this
orientation (ow direction
from bottom to top).
Measures ow in either
d
irection (from top to
bottom or from top to
bottom).

3. INSTALLATION
3.1 Tubing Considerations
(1)The tubing assembly must be thoroughly flushed. Flushing must be performed before meter
installation. Couple a short pipe section in place of the meter (see the ushing set-up given below).
(2)The meter should be installed exercising due care to avoid pipe strains.
(3)When screwing in the ttings, be very careful not to allow metal chips and seal tape protrusions to
get into the meter
.
(4)The meter should be located downstream of the pump.
(5)Flow direction must conform to the arrow mark indicated on the meter body.
(6)The strainer should be located upstream of, and as close to the meter as possible.
(7)The physical orientation of the meter should be such that its nameplate is vertical as shown below.
(8)When installing Size 38 meter in the tubing assembly, screwing torque at the tting should be
held with in
