7. 5 pipe diameters of straight undisturbed flow downstream from the point of measurement The more straight run available the better Undisturbed flow means avoiding sources of turbulence such as valves flanges and elbows You should also avoid swirl cross flow and cavitation in liquids It is important to locate the transducers on a horizontal plane This specifically applies to mounting transducers on a horizontal pipe One transducer cannot be on top of the pipe and one on the bottom because the top of the pipe tends to accumulate gas in liquids and the bottom tends to accumulate sediment in gas and liquids These contaminants can attenuate or block the ultrasonic signal There is no similar restriction with vertical pipes However in liquid applications you should avoid vertical downward flow to ensure a full pipe 1 2 General Information April 2004 BWT Meter Body Single Traverse Meter Body BWT installations typically use a tilted diameter meter body A tilted diameter meter body is so named because the transducers send their pulses at an angle across the diameter of the pipe This type of meter body can be configured as a single traverse or double traverse installation Note The mounting angle for the transducer is typically 45 but other angles 20 30 or 60 can be used as required Tilted diameter can also refer to paths that are off diameter such as the mid radius path A meter body is cr
