C6H Ultrasonic Flow Sensor
Split-type Multi-channel Flow Sensor
Applications and measurement
Monitor up to six water pipelines simultaneously using transit-time ultrasonic measurement. Separate clamp-on sensors connect to a central transmitter, allowing installation without pipe cutting or process interruption.
Applications include liquid cooling systems, industrial cleaning, LCD manufacturing, and medical and pharmaceutical systems. The specified measuring medium is water and the specified pipe material is stainless steel.
About C6H
The C6H combines independent measurement channels with centralised readings on a 2.8-inch colour LCD. Each channel connects to one sensor through an RJ45 interface.
- One to six pipelines monitored simultaneously.
- Clamp-on installation without stopping production.
- RJ45 quick connections for each sensor.
- Colour screen with centralised digital readings.
- 4–20 mA outputs and RS485 Modbus communication.
- DN10–DN32 or DN40–DN50 sensor groups; sizes from the two groups cannot be mixed in one device.
Application and Installation Guidance
- Select a suitable measurement point and clean away oil, rust, dirt and loose impurities. Align the upper and lower clamps around the pipe.
- Use the coupling pad to ensure tight contact without air gaps. Match the sensor's flow direction arrow to the actual flow direction.
- Tighten the four clamp screws evenly. For Level B pipe fit, apply one or two layers of the supplied rubber pads to both sides of the lower clamp's inner wall.
- Connect each sensor cable to its sensor and the corresponding CH1–CH6 RJ45 input on the transmitter.
- Power on and set the actual pipe outside diameter, wall thickness and pipe material for each channel. Save the parameters to start measurement.

Pipe Sizes and Flow Ranges
For stainless steel pipe. DN is the nominal pipe size; check the actual outside diameter against the fit ranges below.
| Nominal size | Level A pipe OD — mm | Level B pipe OD — mm | Overall pipe OD — mm | Flow range — m³/h |
|---|---|---|---|---|
| DN10 | 16–18 | Not listed | 16–18 | 0.1–1.5 |
| DN15 | 18–23 | Not listed | 18–23 | 0.2–3.5 |
| DN20 | 25–29 | 23–25 | 23–29 | 0.4–6 |
