Electromagnetic Heat Energy Measurement (BTU) Meter
eFlow 900H SERIES
1. Introduction
The eFlow 900H series electromagnetic heat meter is a high performance smart meter that features the latest technology. Design structure, manufacturing process, testing & etc are controlled to ensure product’s quality like high accuracy, good performance, wide range and etc. The eFlow 900 will not fail over time as there are no moving parts, therefore, maintenance-free. Furthermore, eFlow 900 uses electromagnetic field technology to measure the flow’s medium. This allows the eFlow 900 to perform well regardless of the quality of liquid.
