Time Delta C
Fuji Electric's Fixed Ultrasonic Flowmeter
The Fuji Electric Time Delta-C ultrasonic flow meter is the latest generation of high performance ultrasonic flow meters using transit-time technology. As it is a non-invasive clamp-on ultrasonic flow meter, the Time Delta-C ultrasonic flow meter is the perfect option for measuring flow rates of relatively clean, homogeneous liquids in closed, filled pipes. The Time Delta-C ultrasonic flow meter is particularly effective in applications where high accuracy is required and the flow meter needs to be installed without shutting down the process.
The Time Delta-C ultrasonic flow meter uses advanced digital signal processing technology to provide a compact, lightweight solution with accuracies that are better than +/-1% of flow rate with minimal influence by the pressure or temperature of the measured fluid. The Time Delta-C offers best in-class anti-bubble performance, which allows for accurate reading with air bubble content as high as 12% volume at 3 ft/s velocity. IP66 (NEMA 4X) protection makes it ideal for installation in internal and external environments.
Push buttons on the front panel make configuration of the Time Delta-C, simple and intuitive. Multiple configurations can also be downloaded from a PC to the Time Delta-C ultrasonic flow meter. Real-time trending and data-logging as well as diagnostics can be performed with the loader software. The software also includes a Sensor Spacing Calculation tool. Flow rates and totals can be transmitted from the Time Delta-C to any other device thru a selection of outputs which include 4-20 mA, Relay, Transistor outputs, RS-232 and RS-485 (MODBUS).
The Time Delta-C ultrasonic flow meter requires clamp-on sensors (detector unit). These sensors clamp to the outside of pipes and cover pipe diameters from 13 to 6000 mm at liquid temperatures from -40 to 200 deg C. The system requires a straight pipe run of 10x and 5x pipe diameters for up-stream and down-stream respectively.
