Note 1 : Flow rates in PVC pipes of Sch80 may not be measurable with the above sensor installation conditions, depending on the nominal

diameter. Contact us in advance.

Note 2 : Select the UL350 for stainless steel piping of nominal diameter larger than 400A (up to 1000A), stainless steel piping of Sch40, and

polyethylene (PE) piping whose wall is thicker than 10 mm.

Note 3 : “V” in the sensor installation column denotes V path, reflex mode and “Z” denotes Z path, diagonal mode.

Note 4 : Two sensor rails must be installed for each piping even if V path, reflex mode is specified for sensor installation. Even if V path,

reflex mode is specified for sensor installation, Z path, diagonal mode may have to be selected instead, due to the effects of

possible piping distortion, inside deposits, or external noises.

Note 5 : For the case of plastic piping of nominal diameter 40A or smaller, two sensor rails, a main sensor rail and a reinforcing sensor rail,

must be installed for each piping to prevent piping distortion.

Note 6 : When the size of measuring pipes is unknown (larger than 400A) or when the piping material may be changed to something other

than those listed in the above selection table, the UL330R may not work well for measuring flow rate.

Note 7 : See the sensor combination in MODEL CODE.
