Pressure
| 127 mm low-flow pressure context | For GT1600 tube sizes 02 and 06, the family data sheet lists threaded-process-connection pressure ratings up to 500 psi / 34.5 bar for size 02 and 450 psi / 31.0 bar for size 06, with lower limits when alarms are included |
Temperature
| Ambient temperature limit | GT1600 family documentation lists -4 F to 125 F / -20 C to 52 C ambient temperature limits |
| Operating fluid temperature limit | GT1600 family documentation lists 33 F to 250 F / 1 C to 121 C operating fluid temperature limits |
Serviceability
| Tube and float service | GT1600 documentation describes tube and float cleaning or replacement without removing the meter body from process piping |
Mounting
| Mounting options | GT1600 family documentation supports in-line, panel-mount, and wall-mount installations depending on configuration |
Safety
| Glass tube fluid caution | Brooks documentation warns not to use glass tube meters with toxic fluids or fluids that chemically react with glass, including water above 140 F / 60 C, steam, alkalis, fluorine, hydrofluoric acid, and molten metal |
