The paint and rust in the pipeline have not been cleaned.<br \/>\n2. Pipe surface is uneven or the flow sensor is installed at the welding joint.<br \/>\n3. Coupling between sensor and pipeline is not good, coupling surface has cracks or bubbles.<br \/>\n4. Sensors is installed on the casing pipe, which weaken the ultrasonic signal.<\/td>\n<td width=\"372\">1. Clean the pipe again and install the sensor.<br \/>\n2. Worn the pipe surface flat or install flow sensor away from the welding joint.<br \/>\n3. Recoat the coupling agent.<br \/>\n4.
