1.Mag-11 Series Electromagnetic Flowmeter — Product Portfolio Summary
Lanry MAG‑11 series electromagnetic flow meter is a robust, high‑performance inline flow instrument developed by Lanry Instruments. It is designed for volumetric flow measurement of conductive liquids in industrial, municipal water‑wastewater, chemical, food‑beverage and mining processes.MAG‑11 supports two mechanical constructions: compact type and remote type, to adapt different site installation constraints
Compact Type: The converter display unit is mounted directly on top of the flow sensor. Compact structure, simple wiring, cost‑effective, ideal for accessible installation locations without high temperature or heavy vibration interference.
Remote Type: Sensor and converter are separated, connected by dedicated shielded signal cable. The display‑converter can be mounted up to hundreds of meters away. Perfect for high‑temperature pipeline, underground pipe‑chamber, heavy‑vibration zones or places where local observation is impossible.
2. What is the working principle of the Electromagnetic flowmeter?
Faraday’s Law of Electromagnetic Induction
- When conductive liquid flows through the measuring tube, conductive fluid cuts magnetic field lines and generates induced voltage signal.
- Two electrodes capture this voltage signal; the converter amplifies, filters and calculates to output instantaneous flow and totalized volume.
- Measuring result will not be affected by fluid viscosity, density, pressure or temperature variations as long as conductivity meets minimum requirement.

4. What kind of medium is the Mag-11 electromagnetic flowmeter suitable for measuring?
MAG‑11 requires medium electrical conductivity ≥ 5 μS/cm
Recommended media:
- Tap water, raw water, sewage & wastewater
- Sludge, slurry, paper pulp
- Corrosive chemical aqueous solution (acid, alkali)
- Viscous conductive liquid, suspension liquid
- Food‑beverage liquid (juice, beverage, sanitary process fluid)
Not applicable: pure distilled water, oil, solvent, gas and steam (non‑conductive substances).
5. Operation & Maintenance Guidance Electromagnetic Flowmeter?
1. Operation: Complete parameter setting (pipe diameter, measuring unit, full‑scale flow, output mode) via local LCD keypad. Enable empty‑pipe alarm function for site protection. Support local display and remote data reading through Modbus/HART.
2. Installation requirements: Ensure pipeline runs full‑filled liquid; keep sufficient straight pipe sections (upstream ≥ 5‑10D, downstream ≥ 3‑5D). Proper instrument grounding is critical for anti‑interference performance. Avoid installation at pipeline high points where gas accumulates.
3. Routine maintenance: No frequent calibration required under normal condition. Periodically inspect electrode and liner for scaling, sediment or sticky deposits. Clean electrodes if signal jumps or reading becomes unstable. Check cable sealing and waterproof status for split‑type model.
4. Troubleshooting: If readings are abnormal, verify full‑pipe status, grounding condition, conductivity and parameter configuration first.
6. Selection Guidelines for MAG‑11
1. Confirm pipe nominal diameter and expected flow range, ensure actual flow velocity falls within 0.3‑10 m/s.
2. Check liquid conductivity ≥ 5 μS/cm.
3. Select proper lining and electrode material according to medium corrosion, abrasion and temperature.
4. Choose construction: integrated type for ordinary accessible site; split‑type for high‑temp, vibration‑heavy or hard‑to‑reach locations.
5. Define connection type: flange / thread / sanitary clamp. Confirm flange standard (ASME B16.5 / BS4504 / EN1092‑1).
6. Specify power supply, signal‑communication outputs, whether explosion‑proof is needed.
7. The Application of Electromagnetic Flowmeter.
- Municipal water supply & sewage treatment plant
- Chemical & petrochemical produced‑water process
- Mining slurry and pulp measurement
- Food, beverage and sanitary pharmaceutical production
- HVAC chilled‑hot water & BTU energy metering
- Industrial circulating water, wastewater discharge monitoring
- Explosion‑proof hazardous‑area conductive liquid process
FAQ About the Electromagnetic Flowmeter
Q1. Can MAG‑11 measure pure de‑ionized water?
No. De‑ionized water conductivity is far below 5 μS/cm, electromagnetic meter cannot work properly. Select ultrasonic flow meter for this scenario.
Q2.Does MAG‑11 need regular calibration?
For general monitoring projects, no frequent periodic calibration. For custody‑transfer billing application, perform on‑site calibration as local regulation requires.
Q3. Can MAG‑11 work for partial‑filled pipe?
No. MAG‑11 must run under full‑pipe condition. Partial‑filled condition will trigger empty‑pipe alarm and wrong readings.
Q4. Can MAG‑11 measure slurry with high solid content?
Yes. Select wear‑resistant lining and matched electrode material. Avoid extremely high solid concentration that causes heavy electrode coating.
Q5. Will sediment or scaling affect MAG‑11 measurement?
Heavy scaling covering electrodes will distort signal. Clean electrode surface if obvious deviation occurs.
