Sensor size selection
The selection of the sensor diameter is not the same
as the diameter of pipe.This option applies to the
following:
A.for Low flow velocity in the pipe and the stable flow rate, to
meet the requirements of the instrumentation on the flow rate
range,we should increase the flow rate of partial area and
select the sensor diameter smaller than the pipe diameter ,and
install another different - diameter pipe before the sensor.
B.In terms of the price, for the magnetic flow meter with large
diameter, the larger diameter you want, you higher price you
will pay; for the low flow rate in the pipe and stable
parameter,the selection of small diameter would be better. It
will not only make the meter work in good condition but also
reduce the cost.
Warning of installing the different-diameter pipe
To avoid affecting too much the distribution of the velocity field and the measuring
accuracy, The center of the cone angle of different diameter pipe should not be
greater than 15,thus we could regard the different-diameter pipe as part of the
straight pipe.
