5. Now you can safely tare (zero) a meter (page 19) using the
tare button on the device, or in the case of a water flow
controller, command the zero set-point (page 28) which will
auto-tare the unit.
► Smooth and consistent source pressure is highly preferable, as any
pulsing or fluctuation in water pressure will hydraulically couple to
the differential pressure sensor, and the resultant flow reading will
jump analogously.
► Please note that, depending on model and flow range, water flow
meters have an inherent internal pressure drop higher than that
of standard gas flow meters of similar flow range. The minimum
water device pressure drop is 2 psig, going all the way to 20 psig
drop in certain models. Your source input pressure must meet or
exceed this specification, in addition to any back pressure you
may have on the downstream end of your process. Please see
pages 51 - 54 of the manual or check our online specifications
chart for model specific details.
Please contact Alicat if you have any questions. We will be happy to help.
