Transit-time flow measurement has become essential for verifying flow rates in clean liquid applications, especially when accuracy, speed of deployment, and non-invasive installation are critical. At Daly Middle East, we frequently support clients across the GCC looking for dependable portable solutions—particularly for water treatment, district cooling, industrial utilities, and plant commissioning.
In this case study, we highlight the PTFM 6.1 Portable Transit-Time Flow Meter from Pulsar Measurement and why it has proven to be one of the most efficient and accurate tools for clean-flow diagnostics and validation projects.
The Challenge
Many facilities—municipal, industrial, and commercial—face difficulties in verifying flow measurements without shutting down the system. Typical challenges include:
- Clean water or treated effluent flowing in underground or inaccessible pipelines
- Need for non-contact, clamp-on measurement
- Requirement for accurate and repeatable readings for troubleshooting or system validation
- Limited space or projects requiring portable, battery-powered solutions
In one such real-world application, a wastewater treatment plant needed to validate the accuracy of its existing meters by checking flow in 300–1200 mm ductile iron pipes with low-velocity effluent. The harsh pipe material and underground mounting made it difficult for traditional clamp-on meters to produce strong signal strength.
The Solution: PTFM 6.1 Portable Transit-Time Flow Meter
Daly Middle East recommended the Pulsar Measurement PTFM 6.1—a non-contacting, clamp-on meter designed specifically for clean liquids. Its advanced transit-time technology provides exceptional accuracy, even on difficult pipe materials.
Key features include:
- Three transducer options to support a wide range of pipe diameters
- Easy installation with clamp-on mounting and intuitive setup menus
- Exceptional signal strength, even on ductile iron pipes
- Portable, rugged enclosure suitable for harsh industrial environments
- Accurate readings on low-flow velocities
- Internal data logger with massive storage capacity for analysis
- USB connectivity for report generation and documentation
From the case study file you shared, the PTFM 6.1 proved its reliability by providing accurate, steady readings where other meters failed, even being described by the customer as:
“Pulsar Measurement is the first to read expected flow on these pipes.”
Project Outcome
After successful trials, the customer:
- Confirmed that the PTFM 6.1 matched expected flow values
- Noted high repeatability and strong signal strength on thick ductile iron
- Purchased additional permanent TTFM 6.1 transit-time meters across the plant
- Retained the PTFM 6.1 portable unit for spot-checking, calibration verification, and system diagnostics
The trial demonstrated the value of accurate non-contacting transit-time flow measurement in difficult pipe applications—delivering both operational confidence and long-term measurement reliability.
