Pulsar Measurement – PTFM 6.1 – Portable is a Pulsar product available from Daly Middle East for professional industrial applications.
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.

The PTFM 6.1 is listed as a portable, IP67-rated clamp-on transit-time flow meter for non-invasive flow verification on clean fluids. It is relevant when a portable check, commissioning activity or temporary survey is required without opening a suitable existing pipe.
Before requesting a configuration, provide the process medium, pipe or channel details, normal and maximum operating range, installation access, temporary or permanent requirement and the output or communication needed by the receiving system. Photographs, drawings and existing nameplate details are useful for replacement or retrofit enquiries.
Compare this model with the ultrasonic flow meter selection guide and the Pulsar Measurement product range to confirm the measurement approach.
What should be provided for a portable flow check? Share the liquid, pipe material, outside diameter, wall thickness where known, flow range, site access and required survey duration.
