Overview:

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



Function:

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)

Set batch flow control;

• compensation: Automatic compensation for temperature/pressure/both
• Signal : Current:***0mA or ***0mA, Voltage:**5V or **5V(or mV) and Resistance: thermal resistance PT**0
• Analog output: Direct current:***0mA or ***0mA output, load ****0 Ohm  Derect Voltage: **5V or **5V output(load no more than **0 Ohm)
• Output signal switch: Output signal:***0mA/**5V, ***0mA/**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.

• signal: Analog :Resistance: PT**0;    Current:***0mA or ***0mA;        Galvanic couple:K;E;      Voltage:**5V or **5V( or mV)
• On-off : start, stop, reset range: photoelectric isolation more than 4V(or customized)
• Output signal:  Analog output:***0mA less than **0Ohm, ***0mA less than **0 Ohm, **5V less than **0Ohm, **5V less than **0 Ohm
