The measuring data and status display as flows:
Note: When there more than one alarm, the alarm status display cycle.
FQH --- Flow high limit alarm FQL---Flow low limit alarm
FGP --- Flow empty pipe alarm SYS --- System exciting alarm
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, English / Korea/ Portuguese / Chinese 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.
9, Converters and sensors coefficients can be set independently. Converter interchangeable.
10, Various output interfaces are available:
Analog output: 4 ~ 20mA or 0 ~ 10mA current loop output
Pulse or frequency output
Switch alarm output
11, RS485 communication, or HART communication option
12, Modular design, ensuring high reliability, consistency, and long-term stability.
