This results in superior stability and reliability, making it suitable for complex and challenging conditions.

PRINCIPLE

As fluid enters the flow meter, it is meticulously rectified and accelerated by our specialized air inlet rectifier. Turbine blades, precisely angled for optimal fluid dynamics, generate torque, initiating rotation once friction and resistance torques are overcome. Within specific flow ranges, the turbine's angular velocity aligns with the fluid's volume flow rate. Utilizing electromagnetic induction principles, a magnetic sensor detects proportional pulse signals from the rotating signal wheel. These signals, post-amplification, filtering, and shaping, are processed by the intelligent flow totalizer's microprocessor, alongside temperature and pressure sensor inputs, culminating in direct LCD displays of volume flow and total gas quantities, providing comprehensive and accurate measurements.
