The Fuji Electric Time Delta-C ultrasonic flow meter is the latest generation of high performance ultrasonic liquid flow meters using transit-time technology. As it is a non-invasive clamp-on ultrasonic flow meter, the Fuji Electric Time Delta-C ultrasonic flow meter is the perfect option for measuring flow rates of relatively clean, homogeneous liquids in closed, filled pipes. The Fuji Electric 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 Fuji Electric 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 Fuji Electric Time Delta-C ultrasonic flow meter offers best-in-class anti-bubble performance, which allows for accurate readings with air bubble content as high as 12% volume at 3 ft/s velocity.
The rugged construction of the Fuji Electric Time Delta-C ultrasonic flow meter makes it ideal for installation in internal and external environments where IP66 (NEMA 4X) protection is required. By utilizing the latest technologies, the Fuji Electric Time Delta-C ultrasonic flow meter is just 2/3 the size of its predecessor, the Time Delta-S.
Configuration of the Fuji Electric Time Delta-C ultrasonic flow meter is simple and intuitive via push buttons on the front panel. Alternatively, free PC compatible software is available, allowing multiple configurations to be stored and downloaded from a PC to the Fuji Electric Time Delta-C ultrasonic flow meter. Real-time trending and datalogging as well as diagnostics can be performed with the loader software. The software also includes a Sensor Spacing Calculation tool. Where flow rates and totals need to be transmitted, the Fuji Electric Time Delta-C ultrasonic flow meter provides a selection of outputs which include 4-20mA, relay, transistor outputs, RS232 and RS485(Modbus).
The Fuji Electric Time Delta-C ultrasonic flow meter requires clamp-on sensors. These sensors clamp to the outside of pipes and cover pipe diameters from 13 to 6000mm (0.5 to 235 inches) at liquid temperatures from -40 to 200°C (-40 to 390°F). The system requires a straight pipe run of 10x and 5x pipe diameters upstream and downstream respectively.
Benefits of the Fuji Electric Time Delta-C Ultrasonic Flow Meter:
Transit Time Ultrasonic Flow Meters – Technology Explained
Transit Time ultrasonic flow meters such as the Fuji Electric Time Delta-C are well-suited for relatively clean fluids with low to moderate aeration. These meters operate by comparing the time for an ultrasonic signal to travel with the flow (downstream) against the time for an ultrasonic signal to travel against the flow (upstream). The difference between these transit times is proportional to the flow, and the flow meter converts this information to flow rate and total. With this technology, the transducers are mounted on the outside of the pipe, providing tremendous advantages over more traditional and invasive flow measurement instruments. This product is virtually maintenance free.
Instrumart is an IDWR-approved flow meter vendor
The Fuji Electric Time Delta-C ultrasonic flow meter is a IDWR-certified flow meter as outlined in the Idaho Department of Water Resources state order requiring flow meters to be installed by water users that divert water in regulated areas from both ground and surface water sources. This flow meter was tested by the staff at Utah State's NIST traceable lab and passed all requirements set by the IDWR and Idaho Department of Agriculture.
