*3: Two sets of transducers are necessary when applying dual
channel/path measurement.
*4: A Tokuchu request is necessary when transducers are
installed where condensation occurs. However the pipe
size must be over 100 mm (Large type or Very large type).
*5: The alphabetic characters in the suffix code represent pipe
sizes and fluid temperature ranges are below.
B: Medium type (25 to 400 mm / 1 to 16 in.)
C: Large type (100 to 2,500 mm / 4 to 98 in.)
D: Very large type (2,000 to 6,500 mm / 78 to 255 in.)
G: General temperature (–30 to +130°C / –22 to +266°F)
H: High temperature (–30 to +200°C / –22 to +392°F)
*6: When the pipe size is less than 50 mm (2 in.), select
N(None) here first and order separately one each of
USPA053 mounting fixture short ruler type, USPA036
fixing chains (0.5 m/1.6 ft length), and USPA097 couplant
weatherproof type. It will avoid any stress that could be
caused by expansion of the pipe after installation. The
couplant weatherproof type can be specified by the code R
for couplant.
