The flow integrator collects, displays, controls, transmits, communicates, prints, and processes various signals such as temperature, pressure, and flow on site, forming a digital acquisition system and control system. It is suitable for flow accumulation measurement and control of various liquids, general gases, superheated steam, and saturated steam; It can be used in conjunction with various flow sensors or transmitters to adapt to various measurement and control scenarios. It adopts mature and widely produced AI series instrument universal hardware, combined with excellent flow integrator software, making the instrument feature rich functions, easy programming, good anti-interference, high reliability, fast delivery, low cost and low price.
