Transit Time Flow Meters

TFXL Ultrasonic

DESCRIPTION

The TFXL ultrasonic transit time flow meter measures most clean liquids and liquids with small amounts of suspended solids or aeration, such as surface water or sewage.

FEATURES

• Bi-directional flow measurement system

• Totalizer options include forward, reverse and net total

• UltraLink® software utility enables in-field flow meter configuration, calibration and troubleshooting, via laptop PC

• Compact enclosure uses large, easy-to-read digital display

BENEFITS

• Reduced material costs: Clamp-on sensor eliminates the need for in-line flanges, pipe fittings, strainers and filters.

• Reduced installation time: May be installed and fully operational within minutes. No need to break into pipelines.

• Reduced maintenance costs: With no moving parts, there is nothing on the TFXL to wear down—no repair kits or replacement parts are needed.

• Easy retrofit: With three standard outputs (4…20 mA, TTL pulse and simulated turbine frequency), the TFXL drops easily into existing DCS and flow monitoring systems.

• Reduced downtime: Installation may be performed on full pipes. No need to shut the process down for installation or maintenance.

APPLICATION

The TFXL ultrasonic flow meter clamps onto the outside of a pipe and does not contact the internal liquid. This advanced product provides instantaneous rate and accumulated flows along with 4…20 mA and pulse outputs. Compact integral mount systems can accommodate pipes/tubing two inches and smaller. Remote mount systems are also available for pipe/tubing sizes 1/2 in. (DN 15) and higher.

OPERATION

Transit time flow meters use two transducers that function as both ultrasonic transmitters and receivers. The flow meters operate by alternately transmitting and receiving a frequency-modulated burst of sound energy between the two transducers. The burst is first transmitted in the direction of fluid flow and then against fluid flow. Since sound energy in a moving liquid is carried faster when it travels in the direction of fluid flow (downstream) than it does when it travels against fluid flow (upstream), a differential in the times of flight will occur. The sound’s time-of-flight is accurately measured in both directions and the difference in time-of-flight calculated.
