Ultrasonic flow meters

Available in three types for a multitude of job profiles.

• PICOTHERM 2e COMPACT — the economy heat meter without data outputs.

System function

To put it simply, the system functions like this: a hot-water meter is installed in the
system’s return pipe — known in the trade as a volume measuring unit.

The rotor RPM is trans- mitted to the calculator, and evaluated together with the signals from the resistance temperature sensors. Each system incorporates two paired sensors, in the supply and return lines.

Depending on the metering job involved, the system can be delivered in different configurations

Wide choice

Volume measuring units are available with all customary nominal flow rates, from Qn 0.6 to Qn 250, and can always be combined with the arithmetic-logic unit, thus opening up extensive application options.

As you can rightly expect, a steel hood protects the flow meter against manipulation.

The flowmeter digital output is often used as input for an energy meter or as input for digital systems for remote reading.

SITRANS FUS380 has two digital output functions that can be individually selected. Pulse output rate is defined when ordering. To get optimal benefit the pulse value must be selected as low as possible.

If the flowmeter forms part of an energy meter system for custody transfer, no further approvals are needed, except possible local approvals on the flowmeter.

The values Qi, Qp and Qs are shown on the system label of the FUS380. Qi (Qmin) means the minimal and Qp (Qnom) the nominal flow rate. Qs is the highest operatable flow rate. The maxium flow rate (Qmax) is 105 % of Qs. The low flow cut-off is 50 % of Qi. In order to obtain best pulse output resolution in the range Qmin to Qs of approx. 100 Hz at Qs, two or three flow values for every dimension can be selected at ordering. Therefore the ordering data table also shows Qp (Qn). This flow rate is between Qi (Qmin) and Qs and indicates the normal or typical flow.

The 2-track SITRANS FUE380 is the custody transfer approved version of SITRANS FUS380. It can be verified and sealed for use in various countries. The approvals (MID, EN 1434 and OIML R75) are valid for energy metering systems. The battery or mains supply powered SITRANS FUE380 has a display that indicates various measurement values and diagnostics. In addition, it features an IrDA optical interface for communication with SIMATIC PDM used for data transfer. Optional add-on RS 232 and RS 485 modules include MODBUS RTU protocol.
