Overview

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.


 

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);
● 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 250Ω )
● 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.

Technique Data
● Input signal
Analog input: Resistance: PT100; Current: 0~10mA or 4~20mA; Galvanic couple: K; E; Voltage: 0~5V, 1~5V (or mV)
