Minimum Flow.
As with any other flow sensor, there is a rate
below which the IP800-Series sensor cannot read. Check the
flow rate table below for the minimum flow rate detectable by
the sensor for a given pipe size.
Calibration (“K-factor”).
The K-factor represents the number
of pulses per gallon the meter produces during a flow test.
This number must be entered into your electronic control to
make it read properly. If the IP800-Series meter is ordered
with a tee fitting, it is factory-calibrated in the fitting and the
K-factor is indicated on the side (see below).

Field Calibration.
It is possible to field-calibrate an IP800-
Series flow sensor to determine an accurate K-factor in the
actual installation. The reason for doing this would be to
compensate for an unusual condition, for instance, applica-
tions with higher viscosity fluid (IP meters are calibrated for
water use) or which lack adequate straight pipe ahead of the
meter. Field Calibration procedures are described in a Tech-
nical Bulletin on our website (www.seametrics.com).
If a saddle or weld-type fitting has been ordered, use the K-
factor calculator at the bottom of the www.seametrics.com
home page to determine the K-factor. In PVC, however, it is
possible to order a saddle pre-installed on a standard length
of pipe, and the fitting can be wet-calibrated in this case.
