Taring Your Flow Meter
Taring is an important practice that ensures
that your flow meter is providing the most
accurate measurements possible. This function gives the flow meter a
good zero reference for flow measurements. For meters with an optional
barometer, taring can also be used to align the internal absolute pressure
sensor with the barometric pressure reading.
