Size code explanation: √ : Object : Standard : Option –: Not available
Note1: Cable glands are not provided. Refer to the part of “Cable connection port” at detector and converter.
Note2: Tri-clamp® is available to use the same joint size instead of ISO2852 clamp except meter size 100mm (4").
Note3: Toshiba’s original ferrule is required to use for LF490 series detectors to keep just fitting between the joint in case
of choosing clamp type.
Note4: Applies to the separate type flowmeter only. Specifying the code C, indicate the length of cable from 1 to 300m in
1 meter increments.
Note5: Consult Toshiba before ordering when choose materials at the wetting parts.
Note6: LF494 have only 3A approved type.
