Interface Item
Description
1
Cable Connector
Supply and electrical interface (see Table 5 for specifications).
2
“Zero” Button
For offset elimination with zeroing. To be pressed for more than 3 seconds to start zeroing.
Zeroing process duration is about 20 seconds.
3

Indicates status of flow measurement is blinking with frequency proportional to flow (~20 Hz
at 100% of full scale). At zero flow it is constantly on.
4
“High” LED
Indicates high flow alarm (see Table 3).
5
“Low” LED
Indicates low flow alarm (see Table 3).
6
“Arrow” Label
Indicates flow direction.
7
Label with Serial Number
Unique serial number for traceability.
