Key Features:
Simple Installation: Setup takes just minutes with no need for configuring pipe parameters. Clamp the ultrasonic sensor onto the pipe, input the inside diameter, and the meter is ready to report flow instantly.
Cutting-Edge Technology: Unlike transit-time or contacting flow meters, the PDFM 6.1 utilizes clamp-on Doppler technology to measure velocity without direct contact with the medium. It excels in challenging conditions with solids or gas present, ensuring accurate flow measurement in applications such as wastewater treatment, sludge handling, and more.
Built to Last: With an extruded aluminum enclosure and IP67-rated connectors, the PDFM 6.1 is built to withstand the harshest environments. Its robust design ensures reliable performance even in outdoor settings.
Portability and Convenience: Each PDFM 6.1 comes in a rugged PELICAN™ case with a clamp-on sensor and stainless-steel mounting kit, making it ideal for temporary installations or verifying existing meter outputs.
Extended Battery Life: The low-power mode enables long-term data logging in remote locations without access to power, ensuring uninterrupted monitoring.
Advanced Signal Processing: Equipped with state-of-the-art signal processing capabilities, the PDFM 6.1 filters out noise and interference, enhancing accuracy and repeatability in challenging applications like dense slurries.
Experience the ease and reliability of the PDFM 6.1 Portable Doppler Flow Meter for your flow measurement needs. Simplify the most demanding applications with confidence, knowing that your flow data is accurate and accessible.
