Measurement Site Selection
The installation of this ultrasonic flow meter is the simplest one of all kinds of Energy Meters. Only one suitable
measuring site needed, plug the transducers on the pipe and then start the measurement.
When selecting a measurement site, it is important to select an area where the fluid flow profile is fully developed
to guarantee a highly accurate measurement. Use the following guidelines to select a proper installation site:
l
Choose a section of pipe that is always full of liquid, such as a vertical pipe with flow in the upward direction
or a full horizontal pipe.
l
Ensure enough straight pipe length at least equal to the figure shown below for the upstream and downstream
transducers installation. Try to avoid Ensure enough straight pipe length at least equal to the figure shown
below for the upstream and downstream transducers installation.
l
On the horizontal pipe, the transducer should be mounted on the 9 and 3 of the pipe, avoiding the position of
6 and 12, in case of the signal attenuation caused by pipe at the bottom sediment or bubble
、
cavitation on the
pipe.
l
Ensure that the measuring site temperature is under the transducer temperature limits.
l
Consider the inside condition of the pipe carefully. If possible, select a section of pipe where the inside is
free of excessive corrosion or scaling.
l
Choose a section of sound conducting pipe.
