Siemens SITRANS FUE380 certified ultrasonic thermal meter flowmeter

The dual channel flowmeter SITRANS FUE380 is powered by batteries or AC power. It can measure water flow in regional heating equipment, local area networks, heat source plants, heat exchange stations, refrigeration equipment, and other conventional water applications.
The SITRANS FUE380 instrument complies with the thermal measurement standards EN 1434, Level 2 and OIML R752, and the measurement parameters are not affected by operation. The certified flowmeter is named SITRANSFUE380.
SITRANS FUS380 and SITRANS FUE380 have exactly the same technical specifications, with the difference being that FUE380 has an authentication mark.

application

SITRANS FUE380 is mainly used for measuring water flow or measuring hot or cold water in energy metering systems.
Combining an energy calculator and a pair of temperature sensors, SITRANS FUE380 can be used as part of an energy meter. For this purpose, Siemens provides the energy calculator SITRANS FUE950.

design

The dual channel design of SITRANS FUE380 ensures maximum measurement accuracy even under insufficient inlet straight pipe conditions. The flowmeter consists of a flow sensor pipeline, 4 transducers/transducer cables, and a signal converter SITRANS FUE080.
Optional integrated or split installation, with a distance of up to 30 meters between the flowmeter and signal converter. When ordering an integrated instrument, the transducer cable is installed properly and ready to use.
The maximum applicable temperature for integrated installation is 120 ° C. The sensor must be isolated to prevent the signal converter from being heated. The signal converter complies with IP67/NEMA 4X/6 protection level.

review

The digital output of a flow meter is usually used as an input for an energy calculator or a remote display digital system.
The SITRANS FUE380 has two independently selectable digital output functions.
When placing an order, the pulse output setting can be specified.
If the flowmeter is used as part of a sealed energy delivery instrument system, no further certification is required except for local certification on the flowmeter.
