A member of the EnduroFlow™ Series, the EF40 Ultrasonic Flowmeter is the first member of the 4th generation ultrasonic flow meters from Spire Metering. Compared with its predecessors, the 4th generation flowmeters feature advanced multi-frequency flow measurement technology, thus, offering wider pipe size coverage, better accuracy and richer features.
The EF40 ultrasonic flowmeter is designed to be installed at a fixed location for long-term flow measurement on a closed pipe, carrying pure liquids or liquids with some suspended particles. EF40 can be equipped with clamp-on or wetted (insertion or flow-cell) type transducers to meet various application challenges.
EF40 flowmeter utilizes cutting-edgetechnologies such as advanced transducer design, low voltage transmission, digital signal processing, self adaptation, and more, to achieve high performance. Its proprietary quality tracking mechanism analyzes the quality of the received signal and automatically tunes the meter system to its optimized condition. This mechanism leads the system to be easily adaptable to pipe material variations and liquid property changes.
EF40 main unit can be programmed to operate at 0.5MHz, 1MHz or 2MHz frequency. Together with transducers of compatible frequency, EF40 is able to measure flow on pipes from DN20 (3/4”) up toDN3000 (120”) with various pipe materials.
As QUALITY is of crucial importance, all transducers are carefully paired, and all flowmeters are wet-calibrated on the flow loop in the factory to further ensure the system accuracy and reliability.
