SITRANS FUE380 7ME341 Ultrasonic Flowmeter
Overview---SITRANS FUE380 7ME341
Siemens engineers develop the 2 - path flowmeter SITRANS FUE380, which can operate on battery or mains power. They design it to measure water flow in district heating plants, local networks, boiler stations, substations, chiller plants (including glycol mixes without type approval), and other general water applications.
Authorities approve the flowmeter FUE380 according to energy meter standards EN 1434 class 2, OIML R 75 class 2 and MID class 2. We protect metrological parameters against manipulation. Siemens names the type - approved flowmeter version SITRANS FUE380. For a standard flowmeter type FUS380 without a type approval, see the section about FUS380.
Technically, the meter types SITRANS FUS380 and SITRANS FUE380 are completely identical, only difference is the calibration limit and the type approval for custody transfer.

Application
The main application for SITRANS FUE380 is measurement of water flow or water flow in energy meter systems for custody transfer in district heating networks or chilled water (including glycol mixes without type approval).
Combined with an energy calculator and a pair of temperature sensors, SITRANS FUE380 can be used as part of an energy meter system. For this purpose Siemens offers energy calculator SITRANS FUE950.
Design
The 2-path design of SITRANS FUE380 ensures maximum accuracy under short inlet conditions. The approved flowmeter consists of a flow sensor pipe, 4 transducers/transducer cables and a transmitter SITRANS FUE080.
The unit is available in a compact or a remote version. It's pre - mount both versions with short coax - cables. Remote transmitter up to a distance of 30 m by one Sensor link cable (SSL).
Compact mounting is only possible up to 120 °C (248 °F). The sensor must be isolated to protect transmitter from heat. The transmitter is available in an IP67/NEMA 4X/6 enclosure.
FUE380 MI-004 approval
The SITRANS FUE380 program is type-approved according to international energy meter standard EN 1434. On 1 November 2006 the MI-004 energy meter directive became effective providing that all energy meters with a MI-004 verification label can be sold across the EU borders.
Testing authorities have verified and labeled the FUE380 as MI - 004 products in accordance with Directive 2014/32/EU of the European Parliament and Council of 26 February 2014 on measuring instruments, specifically Annex IV Thermal Energy Meters (MI - 004), for sizes ranging from DN 50 to DN 1200.
This obtain the MID certification through module B + module D approvals in line with the above - mentioned directive.
Module B: MI-004 Type approval according to EN 1434: 2007 (approved for media water)
Module D: Quality insurance MID approval of production
Manufacturers obtain the MID certification through module B + module D approvals according to the above - mentioned directive. An example of the product label is shown below:

Function
Together with the SIMATIC PDM tool the FUE380 offers the possibility of testing and verifying the flowmeter on site and creating a printed ”Qualification Certificate” with specific data that defines the quality status of the measurement.
The Qualification Certificate shows information about the actual status of the flowmeter:
- General settings, flowmeter and battery information, totalizer values, and pulse output settings
- Detailed information about the transmitter and the sensor functionality, and a main parameter list for evaluating the functionality of the flowmeter
