21. least 10 pipe diameters of straight undisturbed flow upstream and 5 pipe diameters of straight undisturbed flow downstream from the measurement point To ensure undisturbed flow avoid sources of turbulence in the fluid such as valves flanges expansions and elbows 2 Because sediment at the bottom of the pipe and gas at the top of the pipe may cause attenuation of the ultrasonic signal locate the transducers on the side of a horizontal pipe when possible If limited pipe access necessitates top mounted transducers and the sound beam path includes a reflection shift the transducers to at least 10 off top center This will minimize the influence of any sediment or gas on the reflected ultrasonic signals 1 3 4 Cable Lengths Locate the flowcell transducers as close as possible to the electronics console The factory supplies transducer cables up to 1 000 ft 306 m in length If longer cables are required consult the factory for assistance 1 3 5 Temperature Transmitters When installing temperature transmitters in the flowcell locate them downstream of the flow transducers These transmitters should be positioned no closer to the flow transducers than 2 pipe diameters and no further away from the flow transducers than 20 pipe diameters 2 DigitalFlow Multipurpose Ultrasonic Liquid Flowmeter Startup Guide 1 and 2 Channel Chapter 1 Installation 1 3 6 Transducer Cables When installing the transducer cables always observe est
