The I O gt Scale Out sets the parameter the output circuitry will respond to Choices for data to output are either flow or power Additionally this screen sets the minimum and maximum values the outputs will be scaled to Note Transit time measurements are capable of bidirectional flow but Doppler is not The only time setting the Flow at Min Out to a negative value may be necessary is if the meter stays in transit time mode If the meter is used in Doppler mode exclusively or when in hybrid mode the meter switches to Doppler mode set the value for Flow at Min Out no lower than zero An example of a valid use of setting Flow at Min Out below zero would be a transit time application where flow can be in either the forward or reverse direction If for instance a tap water system is capable of 100 gpm forward and 100 gpm in reverse then setting the Flow at Min Out to 100 and Flow at Max Out to 100 would be valid entries If the meter were programed to output a 4 20 mA signal then 4 mA would represent 100 gpm and 20 mA would indicate 100 gpm The zero flow point would be indicated as 12 mA halfway between 4 mA and 20 mA mA 4mA 8 m 12 m 16 ma 20 mA Obeso 100 50 0 e 50 100 GPM Illustration 85 Bidirectional current output 3 UF DYN _DXN BA 02 1307 Sensor mounting B Enter Output Test Mode 4 000 Test 4 20 mA Out mA Test 0 10V Out V Test Frequency Out Hz 4 1
