1. Installing UTXDR Transducers 1 October 2008 Choosing an Installation Location Preparing the Pipe Obtaining Transducer Spacing Locate the transducer measurement point at least 3 ft 1 m from any butt welds or flanges Ideally the location would be in the center of a 20 ft 6 m section of straight pipe Make sure there is 6 in 15 cm clearance on both sides of the pipe for easy transducer installation Note 7o guarantee the specified accuracy of the flowmeter a straight section of pipe and a fully developed flow profile are highly recommended However if such conditions are not possible the transducer location should be such that the acoustic signal travels through the full distribution of the under developed flow profile for best repeatability To prepare the pipe for transducer installation complete the following steps 1 Remove any rust and paint from an area 2 in 5 cm wide by 12 in 30 cm long on one side of the pipe 2 Polish the cleaned area taking care to preserve the original curvature of the pipe 3 With an ultrasonic thickness gage measure the pipe thickness at a minimum of six spots on the cleared area Take at least three measurements at each spot to ensure accuracy The thickness readings should not vary by more than 5 at each spot If you encounter more than a 5 variation at each spot try a different section of the pipe Verify that the wall thickness at both transducer locations has le2.
