BASIC BTU are produced to MID Approval EN1434 - a stringent European standard that ensures that the accuracy and quality remain constant so you can be confident that every meter is as good as the last. The ULTRAFLOW flow sensors use microprocessor technology and ultrasonic measuring techniques. 


Features:
The flow is measured using bi-directional ultrasound based on the transit time method, with proven long-term stability and accuracy. All circuits for calculating and measuring are collected on a single board, providing a compact and rational design in addition to an exceptionally high level of measuring accuracy and reliability.

The 8-digit LED display makes reading the measured value simple and easy. The compact size and lack of moving parts makes the series UHM a low maintenance unit. These features make it great for installation on chillers, and boilers.
