Pulsar Measurement – PTFM 6.1 – Portable Transit-Time Ultrasonic Flow Meter (Clamp-On, IP67)

The PTFM 6.1 Portable Transit-Time Flow Meter from Pulsar Measurement delivers high-accuracy, non-invasive flow measurement in challenging industrial environments. With rugged IP67 construction, advanced signal processing, interchangeable transducers, and intuitive diagnostics, the PTFM 6.1 is designed for both short-term and long-term measurement tasks—without interrupting your process.

Key Features (with subheaders / bullets):

• Non-Invasive & Retrofit-Friendly
  The PTFM 6.1 mounts ultrasonic transducers externally, so there’s no need to cut or intrude into your pipe system. This makes it ideal for process audits, commissioning, or verification tasks.

• Advanced Signal Processing & Diagnostics
  With upgraded hardware and on-screen diagnostics, the PTFM 6.1 ensures confident and repeatable results across pipe materials and flow conditions.

• Interchangeable Transducers for Versatility
  Choose from three transducer sizes (SE16A, SE16B, SE16C), covering nominal pipe sizes from 15 mm (½”) to 1,200 mm (48″). These support metals, plastics, lined pipes, and more.

• Rugged & Field-Ready Design
  Built with IP67-rated aluminum enclosure (IP65 when transducers disconnected), it’s built to survive industrial conditions.

• Built-in Data Logging & Expandability
  Store up to 12.5 million data points, export via USB-C in CSV or proprietary formats, and interface with free Logger software. The modular USB-C port allows future expansion of inputs/outputs.

• High Accuracy & Performance
  • Flow velocity range: ±0.03 m/s to 12.2 m/s
  • Accuracy: ±1% of reading or ±0.0046 m/s (whichever is greater)
  • Repeatability & linearity: ±0.25%

Typical Applications / Use Cases:

• Commissioning & verification of flow systems

• Pump performance testing

• Energy audits in HVAC / chilled water systems

• Water / wastewater flow monitoring

• Process audits in chemical, food & beverage, pharmaceutical, or petrochemical plants

Why Choose PTFM 6.1?
Whether you need to confirm that your installed flow systems are operating properly or temporarily measure flow where you can’t install a fixed meter, the PTFM 6.1 gives you flexibility, accuracy, and the ruggedness to handle real-world sites—all with low installation complexity.
