Yokogawa AXF025 Electromagnetic Flowmeter

• Standard dual-frequency excitation as base configuration, combining stable low frequency and anti-noise high frequency to suppress slurry flow noise, zero drift and pulsating flow interferenceYokogawa E....
• Optional Enhanced Dual Frequency Excitation (HF2) for heavy slurry, low-conductivity media, delivers faster response and ultra-stable measurement.
• Supports fluids with minimum conductivity down to 1 μS/cm, suitable for pure water, dilute chemicals and low-ion liquids.
• Bidirectional flow measurement with independent forward/reverse totalizer.

• Standard accuracy: ±0.35% of measured flow rate
• High-precision optional calibration: ±0.2% of reading
• Repeatability ≤ ±0.05%
• Max pulse output speed up to 10,000 PPS, ideal for batch control & small flow totalization.
• Full bore tube design, zero pressure loss, no internal moving parts.
