C6H · Specialist

Several pipelines. One transmitter.

One transmitter measures up to six pipes, each on its own channel, with all readings on one display. The clamp-on sensors go on without cutting the pipe or stopping the system.

At a glance

What C6H does, in plain words.

What it measures: Liquid flow; How much liquid moves through the pipe.
How it installs: Clamp-on; Sensors fit on the outside of the pipe, so the pipe stays closed.
How it connects: RS485 / 4–20 mA; Wired into control systems over Modbus RS485, or as a 4–20 mA signal.
Pipe sizes: DN10–DN32 or DN40–DN50; DN is the nominal pipe size, roughly the inside diameter in millimetres.

Why C6H

C6H in short.

C6H uses the transit-time ultrasonic principle to measure up to six pipelines at once, with every reading shown on one transmitter.

Its clamp-on, non-intrusive sensors install without cutting the pipe, shutting down or interrupting the process.

Up to 6 independent channels
All readings on one transmitter
Clamp-on: no cutting, no shutdown
RS485 Modbus and 4–20 mA
Pipes DN10–DN50

C6H with six measurement channels

How it works

Sound with the flow arrives sooner.

Two sensors on the same side of the pipe take turns sending sound through the water. Sound travelling with the flow arrives slightly sooner than sound travelling against it; the meter turns that time difference into flow, which is why it needs to know your pipe.

Pipe & installation

What the meter needs to know about your pipe.

These are set up on the meter after installation. Pipe size and transducer type are decided when ordering.

What these terms mean

DN: Nominal pipe size, roughly the inside diameter in millimetres (DN50 ≈ 50 mm).
Clamp-on: Sensors strap to the outside of the pipe. No cutting, no shutdown for installation.
PoE: Power over Ethernet: one network cable carries power and data.
LoRaWAN: Long-range, low-power wireless. Readings travel through a gateway to a network server.
Modbus RS485: A wired connection widely used by building and industrial control systems.
4–20 mA: An analogue signal where the current represents the reading.
