The intelligent flow totalizer controller adopts advanced microprocessor for intelligent control, and is suitable for flow detection and total control of various liquids, general gases, steam, natural gas, etc. Using the look-up table method for density compensation, it can automatically perform high-precision integrated control of superheated steam and saturated steam. Built-in multiple flow accumulation formulas can be adapted to various flow measurement occasions. With a variety of signal input functions, it can be equipped with various pressure/differential pressure and frequency flow sensors (such as orifice, vortex, turbine, etc.), and the above input signals can be realized by simply selecting the instrument menu The easy switching between the two improves the versatility and reliability of the instrument. There are multiple compensation methods (such as temperature compensation, pressure compensation, temperature compensation + pressure compensation, etc.) for selection. The measurement display range is wide, and it can display five digits of instantaneous flow value, temperature compensation value, pressure compensation value, flow, volume (or differential pressure/frequency) value, etc., and 13 digits of cumulative flow value (0-9,999,999,999,999) , High precision, the cumulative value can be accurate to the last three decimal places (0.001). You can also set the internal parameters to make the maximum cumulative value reach 99,999,999,999.99 × 100. It is equipped with measurement status flag display, which can easily observe the measurement object, and the input/output circuits are all optically isolated.
