Series TFXL CLAMP-ON ULTRASONIC FLOW METER FOR LIQUIDS FEATURES BENEFITS

Transcription

1 CLMP-ON ULTRSONIC FLOW METER FOR LIQUIS The 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 m and pulse outputs. Inherent advantages over competitive technologies include ease of installation, and a large, bi-directional measuring range. In addition, the non-contact design eliminates many fluid compatibility issues. The TFXL is housed in an enclosure suitable for outdoor mounting and is available with or without a local display. Compact integral mount systems can accommodate pipes/tubing 2 inches (N 50 mm) and smaller. Remote mount systems are also available for pipe/tubing sizes ½ inch (N 15 mm) and higher. software utility is available for customer configuration and in-field calibration. FETURES May be used to measure liquids with small amounts of suspended solids or aeration (e.g., surface water, sewage). i-directional flow measurement system. Totalizer options include forward, reverse and net total. ULTRLINK TM software utility (free download) enables in-field flow meter configuration, calibration and troubleshooting, via laptop PC. Compact enclosure uses large, easy-to-read digital display. ENEFITS Reduced material costs: clamp-on sensor eliminates the need for in-line flanges, pipe fittings, strainers, and filters. Reduced installation time: the TFXL 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 3 standard outputs (4-20 m, TTL pulse, and simulated turbine frequency), the TFXL drops easily into existing CS and flow monitoring systems. Reduced down-time: installation may be performed on full pipes. No need to shut the process down for installation or maintenance dynasonics.com

2 OPERTING PRINCIPLE Transit time flow meters utilize two transducers which 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. The liquid velocity (V) inside the pipe can be related to the difference in time of flight (dt) through the following equation: V = K**dt, where K is a constant and is the distance between the transducers.

Mount the flow meter or remote transducers onto the pipe and secure. On horizontal pipe, transducer mounting location should be approximately 45-degrees on the side of the pipe. On vertical pipes with upward flow, radial orientation does not matter. 4. Connect and apply C power. 5.
