The ACF-1-KB Integrated Multi-Parameter Orifice Flowmeter features a simple structure with no moving parts, ensuring long-term stability and high accuracy. It offers high standardization and excellent linearity, eliminating the need for in-line calibration. Praised for its flexibility and ease of use, the orifice flowmeter is part of the differential pressure family, which still dominates flow measurement in China. Industry data indicates this category holds an estimated 75~85% market share. Its applications span critical sectors including steam generation, oil & gas, chemicals, metallurgy, power, water, pulp & paper, pharmaceuticals, food processing, and synthetic fibers.
Durable Wellsite Metering: A simple, reliable design guarantees long service life for single-well gas and CBM (Coalbed Methane) measurement.
Precision Without Complexity: Delivers high accuracy out of the box, no wet calibration needed, streamlining deployment and mass production.
Comprehensive Data at a Glance: Provides simultaneous, clear readouts of totalized flow, instantaneous flow, pressure, and temperature.
Adapts to Entire Well Lifecycle: Effortlessly adjust the measurement range via orifice swap to track production through every phase.
Wide Rage Applications: Performs reliably under high pressure and high/low temperature for gas, liquid, and steam measurement.
Seamless Integration: Offers flexible connectivity with 4-channel (4~20)mA analog outputs and a standard RS485 interface.
