Name Function
Flow direction mark Indicates the direction of uid ow.
Mount the detector so that the measured uid ows in the
direction indicated by this mark.
Electrodes Detect an electromagnetic force signal proportional to the
ow rate of the uid passing through the detector.
The electrode material varies depending on the corrosion
characteristics of the uid to be measured.
Electrode cover Houses the electrodes. Do not remove the cover with the
detector installed on a pipe.
Grounding rings Keep reference voltage as zero by grounding the unit.
The grounding ring material varies depending on the
corrosion characteristics of the uid to be measured.
Terminal box
(Remote model only)
Houses the connection terminals used for applying
a standard voltage. Houses the excitation and signal
terminals.
Terminal box cover
(Remote model only)
Keeps the terminals dry and protected. Keep the terminal
box cover on during operation.
