Forward flow
mA Output Direction = Normal
Lower Range Value = 0 g/sec
Upper Range Value = 100 g/sec
Under conditions of reverse flow or zero flow, the mA output is 4 mA.
Under conditions of forward flow, up to a flow rate of 100 g/sec, the mA output
varies between 4 mA and 20 mA in proportion to the flow rate.
Under conditions of forward flow, if the flow rate equals or exceeds 100 g/sec, the
mA output will be proportional to the flow rate up to 20.5 mA, and will be level at
20.5 mA at higher flow rates.
mA Output Direction = Normal
Lower Range Value = −100 g/sec
Upper Range Value = +100 g/sec
Under conditions of zero flow, the mA output is 12 mA.
