Converter (Integral flowmeter)
The contents of (*1) and (*2) described in the converter
specifications are follows.
*1: Select two points from: one pulse output, one alarm
output, one status input, or two status outputs.
*2: For models without an indicator, the configuration tool
(Such as HHT (handheld terminal) or FieldMate
TM
,
etc.) is necessary to set parameters.
Excitation Method:
• Standard dual frequency excitation:
Size 2.5 to 400 mm (0.1 to 16 in.)
