Intelligent flow totalization controller

Intelligent flow totalization controller

The intelligent flow totalization controller uses advanced microprocessor for intelligent control, which is suitable for flow detection and integration 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 integration control on superheated steam and saturated steam. Built-in multiple flow calculation formulas, which can adapt 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 plates, vortex streets, turbines, etc.), and the above input signals can be realized by simply selecting the instrument menu Easy switching between them improves the versatility and reliability of the instrument. With a variety of compensation methods (such as temperature compensation, pressure compensation, temperature compensation + pressure compensation, etc.) to choose from.

Wide measurement display range, it can display the instantaneous flow value, temperature compensation value, pressure compensation value, flow rate, volume (or differential pressure / frequency) value of the whole five digits, and the cumulative flow value of the whole thirteen digits (0-9,999,999,999,999) High accuracy, the cumulative value can be accurate to the last three digits of the decimal point (0.001). You can also set the internal parameters to make the maximum accumulated value reach 99,999,999,999.99 × 100. With a measurement status indicator display, it is convenient to observe the measurement object, and the input / output circuits are optically isolated.
