Insert Electromagnetic BTU Meter
The Insert Electromagnetic BTU Meter is a high-precision thermal energy measurement solution designed for heating and cooling water systems. It combines an insertion type electromagnetic flow sensor with matched temperature sensors (PT100/PT1000) to accurately calculate energy consumption in chilled water and hot water applications.

The insertion design allows easy installation without cutting the pipeline, making it especially suitable for large diameter pipes and retrofit projects. With no moving parts, the meter ensures stable performance, low maintenance, and long service life. It provides reliable and accurate BTU measurement for HVAC systems, district cooling/heating networks, commercial buildings, and industrial energy management.

The system supports various output options such as pulse, 4–20mA, RS485 (Modbus), enabling seamless integration with building automation and energy monitoring systems.
