Wholesale & OEM welcome · Reply in English · Send pipe size, fluid and quantity
Who is this meter for?
Permanent online flow monitoring.
Continuous measurement on critical lines.
Reliable metering for distribution networks.
Feed flow data into BMS / SCADA / PLC.
The YF-C8 is our premium fixed clamp-on transit-time flow meter, delivering ±0.5% accuracy and extending the pipe range to DN25–DN5000 (1″–200″) for the largest lines. The CNC-machined aluminium transmitter, 2.8″ rotatable IPS display and rich I/O make it the choice for high-value, mission-critical measurement.
An optional GPRS DTU module uploads flow data over RS485 to a network platform for remote monitoring and parameter setting, and high-temperature (to 150 °C) or insertion (wetted) transducers are available for special applications.

Installation Methods
- V-method — standard, best accuracy for DN25–DN400
- Z-method — direct path for large pipes DN100–DN2000+
- N / W-method — extended transit path for small pipes (<DN50)
Allow adequate straight run (≥10D upstream of elbows/tees, ≥30D before valves, ≥50D after pumps).
Applications
Large-diameter water supply and transmission, water treatment plants, chemical and petrochemical processes, irrigation districts, industrial process water, and remote/networked flow monitoring via optional GPRS.

Frequently Asked Questions
What is the YF-C8 premium clamp-on flow meter?
The YF-C8 is YS-Flux’s premium fixed wall-mount clamp-on transit-time flow meter for high-value, mission-critical measurement. It combines ±0.5% accuracy with the widest pipe range in the range.
How accurate is it and what pipe sizes does it cover?
It provides ±0.5% of reading (0.15% repeatability) from DN25 all the way to DN5000 (1″–200″), measuring velocity up to 12 m/s with a 500 ms response.
Can it be monitored remotely?
Yes. An optional GPRS DTU module uploads flow data over RS485 to a network platform for remote monitoring and remote parameter setting.
What special transducer and output options exist?
Alongside 4–20 mA, RS485 Modbus RTU, OCT pulse/alarm and a relay, it offers clamp-on transducers to 80 °C, high-temperature transducers to 150 °C, or insertion (wetted) transducers, with cables extendable to 200 m.
