6. Choose from multiple display options, including mechanical counters or regular totalizers, with the flexibility to add temperature and pressure compensation. Powered by long-lasting lithium batteries, these options ensure ease of use and adaptability.

7. With a pulse frequency signal output, this device excels in total quantity measurement and computer connectivity, offering zero drift and robust seismic resistance. High-frequency outputs (3-4kHz) provide enhanced signal resolution.
8. Our gas turbine flow meter is fortified with magnetic induction or photoelectric sensors for rapid signal detection, delivering fast response times and inherent self-inspection. This results in superior stability and reliability, suitable for complex conditions.

PRINCIPLE

As fluid enters the flow meter, it is precisely rectified and accelerated by our specialized air inlet rectifier. Turbine blades, 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.
