Product description
The 2-track ultrasonic flowmeter SITRANS FUS380 and approved SITRANS FUE380 comes as
battery or mains powered and is designed to measure water flow in district heating plants, local
stations, substations, chiller plants and other general water applications including treated waste
water.
The SITRANS FUS flowmeter is available in the following variants:
•
FUS380: A universal flowmeter with selectable settings.
•
FUE380: A type-approved flowmeter dedicated to measure flow in a heating system.
SITRANS FUE380 is approved according to heat meter standards EN 1434
class 2, OIML R75 class 2 and MID.
FUE380 may be marked „neutral“ or have a country-specific approval label,
depending on selection of flowmeter setup when ordering.
Both flowmeter types SITRANS FUS380 and FUE380 are available in either compact or remote
versions and electrical wiring and operation are identical for both types. The maximum permissible
distance between sensor and transmitter is 30 meters.
The flowmeter comes as a transmitter part FUS080 and a sensor part FUS300. This two parts
can be only ordered together as a flowmeter system type FUS380 or FUE380. For FUS380 a spare
part transmitter can be ordered separate (see FI01 catalogue). For FUE380 is this not allowed
according the approvals. For both systems the sensor part cannot be ordered without a
transmitter.
In FUS380 parameters and pulse output are preset from factory and protected via software lock.
A software tool is required to change parameters.
In FUE380 - metrological parameters and pulse output are preset from factory and protected via
hardware lock and sealings to avoid manipulation.
No settings of installation are required as all parameters are set from factory (plug and play).

Service
In order to locate and diagnose failures, a software tool for diagnosis and re-programming of
outputs is available. Failure information is available on the display. Failures are stored in memory,
and can be accessed via the infra-red communication port.
(Software for diagnosis and setting of parameters is available from Siemens Automation and
Drives, Process Instrumentation and Analytics).
