MSP430FR6047: No signal detected in up and downstream channel

Part Number: MSP430FR6047

Hello Eddie,

I just received my EVM430-FR6047 board this week and I have purchased 2 www.steminc.com/.../ultrasonic-flow-sensor-1mhz-send-receive ultrasonic sensors to implement a non-invasive water flow meter but I can not get the USS Design Center to detect a signal.  The Errors tab displays "No signal detected in up and downstream channel."  Obviously I've got something amiss in my configuration but I don't know what it is. I have read a response of your and you reference www.ti.com/.../slaa837.pdf but I can't access this file.  Has this file moved or been superseded? 

Thanks,

Dave

    Thank you for the updated pointer. This did help me at least get a signal by wetting the sensors and placing them on opposite sides of a 3/4" copper pipe. However, I am trying to implement a non-invasive flow solution as pictured on the right side of page 8 of www.ti.com/.../swmp003.pdf. What is the recommended way to attach sensors to the pipe as depicted in this drawing? Is there a recommended angle the sensors should be placed at? Is there a recommended material to use for holding the sensors? I was hoping to use a 3D printed device. Thoughts on this approach?
