YOKOGAWA ADV161-P01
Product Introduction:
The ADV161-P01 is a high-accuracy electromagnetic flowmeter from Yokogawa’s ADMAG AXF product line. It is engineered for precise volumetric flow measurement of electrically conductive liquids in industrial process environments. The meter operates based on Faraday’s Law of Electromagnetic Induction and delivers reliable performance across a broad range of process conditions including water, wastewater, chemicals, and slurries.
Detailed content
Measurement Principle:
The flowmeter generates a magnetic field across the flow tube using excitation coils. As the conductive fluid passes through this magnetic field, an electromotive force (EMF) is induced proportional to the average flow velocity. Electrodes mounted flush with the tube liner detect this voltage, which is directly proportional to the volumetric flow rate.

Applicable Industries:
- Water and Wastewater Treatment
- Chemical and Petrochemical Processing
- Food and Beverage (Sanitary Applications)
- Pharmaceutical Manufacturing
- Mining and Mineral Processing
- Pulp and Paper Industry
- Power Generation (Cooling Water)
Installation Requirements:
- Install in full-pipe conditions only — the tube must be completely filled with liquid at all times
- Maintain minimum 5D upstream and 3D downstream straight pipe runs (D = pipe diameter)
- Ensure proper grounding of the flowmeter and piping system
- Avoid installation near strong electromagnetic interference sources (large motors, VFDs, welders)
- Use shielded cable for signal wiring; ground the shield at one end only
- Orient electrodes horizontally for sanitary applications to prevent air bubble accumulation
Usage Precautions:
- Never run the flowmeter with an empty tube — this will damage the liner and electrodes
- Verify fluid conductivity exceeds 5 μS/cm before commissioning
- Perform zero calibration with the pipe full of stationary process fluid
- Clean electrodes regularly in dirty or coating-prone fluids
- Do not exceed the maximum rated process pressure or temperature for the selected liner material
- Ensure flange gaskets do not protrude into the flow stream
