Application---SITRANS FUS380

The main application for SITRANS FUS380 is measurement of water flow or water flow in energy meter systems in district heating networks or chilled water (including glycol mixes).

Design

The 2-path design of SITRANS FUS380 ensures maximum accuracy under short inlet conditions. The 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. Both versions are pre-mounted 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.

Function

Together with the SIMATIC PDM tool the FUS380 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

Integration

Users often use the flowmeter digital output as input for an energy meter or as input for digital systems for remote reading.

Engineers design FUS380 to have two digital output functions that users can individually select.

Customers define the pulse output rate when ordering. To get optimal benefit, users must select the pulse value as low as possible.

If an energy meter system for custody transfer incorporates the flowmeter, the system requires no further approvals, except for possible local approvals on the flowmeter.
