The USZ 08 ultrasonic flowmeter with the
USE 09 ultrasonic electronic system is
supplied with two case variants:
-
with the mere electronics case: here
connection is to be made directly at the
electronics card (standard with the
USE 09);
-
with an additional terminal box: in the
case of this version, connection is
basically to be made in the terminal box
(standard with the USE 09-C, optional
with the USE 09).

If the meter is operated in conjunction with a Flow Computer/ultrasonic computer of the
ERZ 2000 USC series
, the computer is to be connected to the
RS 485 1
interface. Due to the fact
that the parameters of the meter are stored in the ERZ 2000 USC, you have to make sure that the
correct computer is connected to the measuring element (compare the serial numbers of the
measuring element on both data plates).
