SKU: Promag L 400

Highlights

  • Measuring Range: 9 dm³/min to 162 000 m³/h (2.5 gal/min to 1030 Mgal/d)
  • Accuracy: Volume flow (standard): ±0.5 % o.r. ± 1 mm/s (0.04 in/s)
  • Suitable for fluids producing buildup and for abrasive fluids e.g. potter's clay, lime milk, ore slurry
  • Process temperature from –20 to 90 °C, configurable with different liner material
  • Weight-optimized sensor: Up to 30 % less sensor weight

Fields of application

  • For standard applications in the water and wastewater industry
  • For abrasive fluids (e.g. potter's clay, lime milk, ore slurry)
  • For fluids producing buildup (e.g. wastewater sludge)

Details

The weight-optimized Proline Promag L 400 from Endress+Hauser is an electromagnetic flow meter designed for applications in the water and wastewater industry. Due to its lap-joint flange concept, the flowmeter offers flexible and easy installation. Promag L 400 saves time and costs thanks to the broad functionality of its water- and wastewater-optimized transmitter. In addition, Heartbeat Technology ensures compliance and process safety at all times.
