Description
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.
Key Features
- Measures both heating and cooling energy (BTU / kWh)
- Clamp-on flow + clamp-on temperature sensors — no process shutdown
- Energy accuracy ±2.0%; temperature pairing ±0.2 °C
- DN25–DN2000 pipe range
- 4–20 mA, RS485 Modbus RTU, OCT and relay outputs
- 2.4″ rotatable IPS LCD, Chinese/English menu
- IP54 transmitter / IP68 sensors
