Liquitrend QMW43: Continuous Build-up and Conductivity Monitoring for Your Liquids

The Liquitrend QMW43, from Endress+Hauser, is a compact and versatile sensor designed for continuous monitoring of two key properties in liquids and suspensions: build-up thickness and conductivity.

Here’s what makes the Liquitrend QMW43 valuable for various industries:

• Applications:
  • Food and beverage production: Ensures product quality by monitoring build-up of ingredients or residues in tanks and pipes.
  • Chemical processing: Optimizes cleaning cycles and detects media differentiation in vessels.
  • Pharmaceutical manufacturing: Maintains process consistency by monitoring buildup of materials during production.
• Measurement Capabilities:
  • Build-up Thickness: Continuously measures the accumulation of material on the sensor surface within a range of 0 mm to 10 mm.
  • Conductivity: Accurately measures the electrical conductivity of the liquid, typically ranging from 0 µS/cm (microsiemens per centimeter) to 100 mS/cm (millisiemens per centimeter). This provides valuable insights into liquid concentration or composition changes.
• Unique Features:
  • Combined Measurement: Provides a comprehensive picture of your liquid’s behavior by simultaneously measuring build-up and conductivity.
  • Capacitive-Conductive Measuring Method: Ensures reliable performance in various liquids, including conductive and non-conductive media.
  • Compact Design: Integrates easily into existing pipelines and tanks due to its small footprint.

The Liquitrend QMW43 offers additional benefits that improve process efficiency and reliability:

• Wide Operating Range: Functions effectively in process temperatures from -20°C to +100°C (-4°F to 212°F), with short-term peaks up to 150°C (302°F).
• Durable Construction: Withstands pressures up to 25 bar (362.5 psi), making it suitable for various industrial environments.
• Easy Installation: Available with various thread connections (G1″, G3/4″, M24) for seamless integration into your existing process setup.

Overall, the Liquitrend QMW43 is a valuable tool for industries that rely on consistent product quality and efficient process control. Its ability to monitor both build-up thickness and conductivity provides a deeper understanding of your liquids, allowing you to optimize cleaning procedures, ensure product homogeneity, and improve overall process reliability.
