For efficient water and wastewater management, precise monitoring of flow parameters is key, making clamp-on ultrasonic flowmeters like Flexim’s indispensable.
This non-intrusive technology is proving to be a reliable and cost-effective solution, particularly in situations where traditional meters may be inconvenient to use, or a temporary replacement is required.
The evolution of flow metering technologies
From ancient water clocks to contemporary ultrasonic meters, the evolution of flow measurement has been remarkable. Early industrial flowmeters, using fluid displacement methods, have given way to diverse options like vortex meters, Coriolis meters, and ultrasonic meters that offer unique advantages.
Benefits of clamp-on ultrasonic flowmeters for water and wastewater management
Clamp-on ultrasonic flowmeters such as Flexim’s are versatile and cost-effective, and boast numerous helpful features:
- Suitable for a wide range of fluids, such as water and
- Non-intrusive nature, causing no pressure drop, ensuring the integrity of the water or wastewater flow.
- Minimal disruption during installation.
- Long working life due to the absence of moving parts.
- No routine maintenance or periodic calibration required.
- Ability to measure both low and high flows.
- Operation in harsh and hazardous environments.
- Easy data transfer via optional digital communications outputs.
- Low capital cost.
- Compatibility with various pipe sizes using one clamp-on meter.
- Dual-channel and 4-channel models for improved measurement uncertainty in large diameter pipes.
- Portable versions for temporary checks or process monitoring.
Transit-time technology in water and wastewater
One standout feature that is particularly noteworthy for the water and wastewater industry is the use of transit-time technology, enabling clamp-on meters to be attached externally to pipes. These meters are capable of laboratory accuracy better than 0.5%, installed accuracy better than 1% and provide excellent repeatability, reliability and cost-effectiveness. Transit-time flowmeters are particularly useful for applications that demand long-term measurement accuracy, and are a wise choice for processes with less than ideal water conditions where small particles are present.
User-centred design for water and wastewater professionals
Only by understanding the industry’s needs, unique challenges and daily realities can a user-centred clamp-on flowmeter design be developed. This results in a product that is not only technologically advanced, but also practical and easy to use.
Applications of clamp-on ultrasonic flowmeters for liquid flow metering
With diverse applications, clamp-on meters measure a wide range of fluids, including ultra-pure water and sewage. Their three main applications include fixed permanent installations with virtually zero maintenance, through to versatile portable check flowmeters.
Fixed installations: Clamp-on ultrasonic flowmeters like Flexim’s, excel in fixed installations. Retrofittable without process shutdowns, they offer accuracy, cost-efficiency, and reliability in measuring various liquid flows.
Portable versions: Portable ultrasonic flowmeters provide a short-term survey and monitoring solution. Compact and lightweight, they offer versatility for temporary installations and are hassle-free to use.
Proven technology
In real-world scenarios, clamp-on ultrasonic flowmeters prove their worth every day across a range of water and wastewater management applications, delivering accurate and reliable measurements that contribute to streamlined processes, leakage reduction and welcome CAPEX and OPEX cost savings.
As the industry continues to evolve, and grapple with the challenges of population growth, migration and necessary infrastructure improvements, clamp-on ultrasonic flowmeters are playing a pivotal role in enhancing efficiency, reducing operational downtime, and optimising resources in water and wastewater management.
