Overview
The ST700 Flange Mount Pressure Transmitters are ideal for critical applications such as natural gas custody transfer and energy and material balances, where accuracy and stability are of utmost importance. Four ranges are available:
| STF724/ STF725 | -400 to 400 in H2O | -1000 to 1000 mbar |
| STF732/ STF735 | -100 to 100 psi | -7.0 to 7.0 bar |
| STF72F | -400 to 400 in H2O | -1000 to 1000 mbar |
| STF73F | -100 to 100 psi | -7.0 to 7.0 bar |
