Custom DN600 Electromagnetic Flow Meter for Wastewater Treatment

Municipal Wastewater Treatment

Client Industry:

Municipal Wastewater Treatment

Challenge:

Measuring large flows with high accuracy and fluctuating flow rates

Solution:

Custom 6-Electrode DN600 Magnetic Flow Meter

A wastewater treatment plant required a high-precision flow measurement solution for monitoring large-volume effluent discharge. After detailed consultations, Metlan Instruments designed a custom DN600 electromagnetic flow meter (EMF) with a 6-electrode configuration and a chloroprene rubber (CR) liner, tailored to the client’s abrasive, particle-laden wastewater conditions. The solution ensured accuracy across varying flow rates while addressing durability challenges.

Client Background

  • Industry: Municipal Wastewater Treatment
  • Application: Effluent discharge monitoring

Challenges

Measuring large flows with high accuracy, despite:

  • Fluctuating flow rates.
  • Highly abrasive, solid-laden wastewater.

Solution: 6-Electrode DN600 Magnetic Flow Meter

Metlan Instruments engineers developed a multi-electrode mag meter with the following features:

Electrode Configuration:

  1. Bottom Electrode (Grounding):
    • Ensures stable signal grounding in low-conductivity conditions.
    • Reduces electrical noise from fluid variability.
  2. Top Electrode (Full-Scale Measurement):
    • Optimized for high-flow scenarios (>80% capacity).
  3. Dual Electrodes (Left & Right Sides):
    • Lower Pair: Positioned near the pipe centerline for low-flow precision (<30% capacity).
    • Upper Pair: Activated during mid-to-high flows for seamless measurement across the full range.

Client Feedback

“The 6-electrode design eliminated our low-flow measurement gaps, and the chloroprene rubber liner has held up remarkably against the abrasive sludge.”
