(always for DN1–DN8
[1/25”-5/16”)
Comment:
We recommend that shielded output cables be used with the shields connected to earth at one end.
!
Attention!
If the flowmeter primary includes a preamplifier for low conductivity of for small flow-
meter size DN 1 to DN 8 [1/25” to 5/16”], then the voltage supply ±12 V DC must be
connected to the terminals U+ and U- and be connected to the flowmeter primary as
well as at the converter.
