EASTERN INSTRUMENTS CentriFlow Quick Start Manual

When the CentriFlow® Meter is sent from the Factory it is set with Default values for the Static
Calibration and the Calibration Voltage, which were chosen for the particular material being
measured with the meter. As described in the previous Section, the Static Calibration is an
adjustment that ranges the Transducer, the Measurement Element of the meter. This Setting
will not change unless the Electronic Full Scale is changed.
The Calibration Voltage, however, is the adjustment that is made to Calibrate or Site Calibrate
the Electronics to a particular application. Although the Factory setting may be quite accurate,
it is likely due to differences in installation, feed systems, and material being measured, that
an adjustment be made after the CentriFlow® Meter is installed. This procedure is very simple
and will require a means of capturing material that is run through the meter and weighing that
material. Depending on the Configuration of the CentriFlow® Meter, either Type I or Type II,
the method of capturing the material to be weighed will be different. For a Type I Configura‐
tion the material can be captured after it leaves the Pan Section of the meter, if the
installation allows, or at some other point in the flow path after it has been measured by the
CentriFlow® Meter. The closer the capture point is to the end of the Pan Section of the meter
the less likely that there will be loss in the measurement sample and therefore less likely that
there will be an error in the Calibration of the Electronics. It is important not to come in con‐
tact with the Pan Section when capturing the measurement sample so that the Electronics
does not give incorrect results from measuring the contact. Always remember to fully secure
the door back to the enclosure before resuming normal flow through the meter.
When performing the Site Calibration, it is recommended that a minimum of five samples be
taken before making any Adjustments to the Electronics. Also, it is recommended that the
sample run be a minimum of 10 seconds long. This will allow a reasonable amount of material
to be run through the CentriFlow® Meter ensuring an accurate adjustment to the Calibration.
The procedure is explained as follows:
Step 1: Make sure that the TOP.RUN page is accessed to begin the procedure. Press the
Reset Button on the Lower Left to reset your count to zero before running product
through the meter.
Step 2: Run product through the meter for a designated period of time, collecting the
material in some manner after it has passed through the meter.
