Developed with embedded microprocessor and instrument control technologies, this unit features compact footprint, intuitive operation, clear local readouts, precise flow regulation, corrosion resistance and high-temperature tolerance, with seamless switchover between manual and automatic flow control modes. Optimized for high-pressure water and polymer injection projects, it resolves longstanding industry challenges of unstable, inconsistent and inaccurate injection rates, cutting labor and material costs while delivering technical assurance for pipeline loss reduction and production enhancement. It is widely adopted for automatic measurement and control in oilfield injection allocation, chemical processing, research laboratories and industrial wastewater treatment.
