3. FLOW SYSTEMS EMC 0da Sono Trak Doppler Ultrasonic Flow Meter The Sono Trak Doppler ultrasonic flow meter is a non invasive ultrasonic flow metering system Based on the principles of the Doppler effect it calculates flow velocity by sensing and measuring the frequency shift in motion from reflective materials within a liquid Benefits e Non invasive design e Low cost simple installation Fits pipe sizes from 1 to 100 25 to 2540 mm outside diameter Rugged and maintenance free no moving parts No pressure drop and no costly process shutdowns Reliable and accurate flow readings typically provides 2 0 full scale accuracy and 0 1 repeatability Features e Automatic gain control as flow profile changes so does the electronics signal e Noise immunity to variable frequency drive VFD e User friendly easy to program display with on screen prompting and keyboard entry e Digital signal allows for cable lengths up to 5000 1524 m e AC or DC operation e Fixed and portable units available Overview The Sono Trak Doppler flow meter uses advanced signal processing technology that dramatically increases the accuracy of flow rate measurement Its accuracy ratings are typically 2 0 of full scale accuracy and repeatability is 0 1 of reading This flow metering system uses two transducers mounted side by side operating as ultrasonic signal transmitters and rece

8. ths of up to 5000 1524 m are available Doppler Placement The ideal placement of the Sono Trak Doppler flow meter is within 20 diameters of straight run upstream and 10 diameters of straight run downstream between the meter and any disturbance of the flow however the meter has worked with straight runs of as little as 5 diameters upstream and 2 diameters downstream Piping Conditions The Sono Trak Doppler flow meter fits pipe diameters from 1 to 100 25 to 2540 mm e Pipes should be cleaned with all paint and scale removed e Horizontal pipe mounting is recommended Clamp on mounting The Sono Trak Doppler flow meter is configured with clamp on transducers When installed the transducers sense fluid flow through a pipe and send this information to the system electronics The electronics then convert transmit and display the received data External clamp on sensors are ideal for smooth clean pipe surfaces and are installed without shutting down flow When clamp mounting the flow meter attach the sensors side by side in a position approximately 7 to 11 o clock on the outside of the pipe Use stainless straps nylon belts or bungee straps and a steel chain to secure the clamps in place general specifications a Use only a sonic coupling medium to transmit the energy from the transducer crystals through the pipe wall and into the flow to be measured Any type of non fibrous grease or gel will suffice
