The Partially-filled type electromagnetic flowmeter uses Faraday's Law of electromagnetic induction in the same way as conventional electromagnetic flowmeters to measure the flow rate.
However, new method is adopted for the electrode and the coil arrangement.
Direction of magnetic field is horizontal because a positon of electrode is designed at the bottom of measurement tube.
A reference point of potential is detected in grounding ring at the end of detector pipe.
Directly detecting electromotive force following flow volume, the flowmeter achieves a high-accurate measurement continually even in low-level flow condition.
High accuracy within +/-2%FS from low-level to full-filled condition.
Unaffected by wave and floating solids on the fluid surface.
Mud, sands and other solid sediment don't stay at the bottom of the detector pipe.
High reliability and easy maintenance.
No Pressure loss.
Unnecessary for the additional piping work such as lifting the downstream pipe section to fill the detector pipe.
