FEATURES
1, Intelligent Excitation: Sensor resistance ranges from 30 to 110 ohms. The excitation voltage can be automatically adjusted according to the impedance, which can reduce heat of the circuit board and the temperature drift.
2, Real-time drift control technology: Eliminate automatically the potential drift of measuring electrode and the amplifier circuit drift.
3, Turndown ratio 150:1
4, Multiple variables can be displayed simultaneously: instantaneous flow, total flow, flow rate, positive flow, negative flow, and the alarm state.
5, Chinese / English support.
6, Data backup and restore.
7, Various alarm functions: support excitation, pipes empty, upper and lower alarm.
8, Small flow linear correction functions: Support small flow four-point linear correction.
