Introduction
At Daly Middle East, we’re constantly looking for instrumentation solutions that deliver reliable performance even under the most demanding conditions. That is why we partnered with Pulsar Measurement and introduced the PDFM 6.1 Portable Doppler Flow Meter into our portfolio. In this case study we highlight how the PDFM 6.1 delivers accurate, non-invasive flow measurement in challenging environments, the benefits it brings to our clients, and how Daly Middle East can support deployment, service and technical expertise across the GCC.
Challenge
Industrial and municipal flow measurement can be complicated by conditions such as pipes containing solids, aerated water, slurries, viscous liquids or abrasive media. Traditional contacting or transit-time clamp-on meters often struggle or require extensive setup and maintenance. Clients in the region frequently need a meter that is quick to deploy, robust, and capable of operating reliably in harsh environments.
Solution – PDFM 6.1 Highlights
- The PDFM 6.1 offers clamp-on Doppler technology, enabling measurement without interrupting the process or requiring immersion of sensors.
- It’s capable of measuring flows in pipes from 12.7 mm to 4.6 m internal diameter and flow rates from ±0.03 m/s up to 12.2 m/s.
- The unit is built for rugged environments: extruded aluminium enclosure, IP67 connectors, bright display and carried in a PELICAN™-type case.
- It features advanced signal processing to filter out background noise/interference and improved repeatability in dense slurries or aerated fluids.
- A low-power logging mode makes it suitable for long-term monitoring where power is unavailable.
Implementation by Daly Middle East
As distributor for Pulsar Measurement in the region, Daly Middle East provided full support for selecting the correct meter configuration, performing on-site commissioning and offering training and technical back-up. Our service team handled the rugged onsite clamp-on installation ensuring minimal downtime and rapid deployment.
Results & Client Benefits
- Rapid deployment: The clamp-on sensor meant no shutdown of the process, and minimal preparation.
- High accuracy and reliability in challenging fluids containing solids or air bubbles where other technologies may fail.
- Durability for harsh GCC/industrial conditions with robust housing, IP rating, and field-friendly packaging.
- Flexibility: The portable nature of the PDFM 6.1 makes it ideal for temporary measurement, validation of existing systems or permanent monitoring in difficult-to-access installations.
- Data logging: With 12 million point capacity and USB-C/PC software output, clients can easily export, review, and analyse flow trends.
Conclusion
In environments where measurement is tricky, the Pulsar PDFM 6.1 delivers a reliable, easy-to-use solution. With Daly Middle East’s local expertise, clients in the GCC now have access to this advanced portable Doppler flow meter backed by full technical support and service.
