The LMag-i1 flow meter incorporates the latest digital signal processing (DSP) to achieve the performance of an in-line magnetic flow meter with the flexibility and easy installation of an insertion meter.
Exceptional performance and value
Cost-effective insertion-style design provides the accuracy and reliability found in magflow meters.
Multiple outputs
Three programmable pulse outputs and one analogue output are provided with each meter.
User-friendly backlit display & user interface
‘Smart Button’ technology in the easy to read, backlit display simplifies page navigation and programming, eliminating the need for configuration tools.
Simple installation and commissioning
Factory programmed and ready for use upon delivery. All process data and programming functions are accessible via front panel display and keyboard.
Ideal for HVAC applications
Interfaces directly with your Building Management System to handle the demanding flow measurement requirements in modern HVAC management applications. Hand insertable up to 27 bar and hot tappable so system shut down is not required.
Features
The LMag-i1 features a single monolithic coil designed to create a uniform magnetic field across the entire pipe, essential for accurate flow measurement in installations with less than ideal flow profiles.
