SF Series intelligence Flow Integrating Instruments

SF Series intelligence Flow Integrating Instruments applies to match with many kinds of flow meter sensor or transmitter for display or integrating signals of flow, temperature, pressure, etc.

Calculate and accumulate mass flow automatically; Calculate and accumulate standard volume flow automatically; Display instant and accumulate flow value simultaneously (totalizer unit are optional);

Switch the display among instant/accumulative flow value, differential pressure value, frequency value, temperature/pressure compensation measured value;

Set cutoff value for small flow signal (no accumulation when instant flow less than set value);

Compensation: Automatic compensation for temperature/ pressure/both

Signal input: Current: 0~10mA or 4~20mA, Voltage: 0~5V or 1-5V ( or mV) and Resistance: thermal resistance PT100

Analog output: Direct current: 0~10mA or 4~20mA output, load 0-500Ω

Direct Voltage: 0~5V or 1~5V output (load no more than 250 Ω)

Output signal switch: Output signal: 0~10mA / 0~5V, 4~20mA/1~5V

Data storage and lock:

Set data permanent preservation after power off, then the accumulate flow value will be preserved permanently; set the parameter lock function, which could protect the set values of automatic compensation for temperature, pressure, or temperature and pressure by encipherment.
