Who is this meter for?
Meter heating and cooling energy.
Sub-meter thermal energy for billing.
Monitor thermal efficiency.
Log flow and supply/return temperature.
The YF-E6 is a clamp-on ultrasonic energy (heat/cooling, BTU) meter. It combines clamp-on flow measurement with paired supply- and return-pipe temperature sensors to calculate thermal energy — for both heating and cooling — with no pipe cutting or shutdown.
Based on the proven C6 fixed platform, it covers DN25–DN2000, reports energy to ±2.0% and temperature pairing to ±0.2 °C, and provides 4–20 mA, RS485 Modbus RTU, OCT and relay outputs for building energy management and billing/sub-metering.

Frequently Asked Questions
What is the YF-E6 clamp-on energy meter?
The YF-E6 is a clamp-on ultrasonic heat/BTU (thermal energy) meter. It combines a clamp-on flow measurement with supply and return temperature sensors to calculate heating or cooling energy without cutting the pipe.
How does it calculate energy?
It multiplies the measured flow rate by the temperature difference between the supply and return lines and the fluid’s heat properties, reporting heat or cooling energy (e.g. kWh/BTU). Temperature pairing accuracy is ±0.2 °C.
What is its accuracy and pipe range?
Flow accuracy is ±1.0% of reading and energy accuracy is ±2.0%, over DN25 to DN2000 (1″–80″) at velocities from 0.1 to 12 m/s.
Where is the YF-E6 used and what outputs does it have?
It is used for HVAC and district heating/cooling energy metering, chiller and boiler monitoring and tenant billing. Outputs include 4–20 mA, RS485 Modbus RTU, OCT and a relay, with IP68 flow and temperature sensors.
