Clamps on like a pipe clamp

On the pipe in minutes – no drilling, no welding, no shutdown

The VC 600 measures from the outside. The clamping system wraps around the pipe and the measuring unit is fastened to it with a screwdriver. The pipe stays closed and pressurised, and production keeps running.

  • 90 %less installation time
  • 0pipe interventions – no drilling, welding or cutting
  • 100 %leak-free – no seals, no contact with the medium
  • Ø 25–90 mmpipe outer diameter with one measuring unit
  1. VC 600 clamping system fitted on a pipe

    Fit the clamping system

    Place the 316L stainless steel quick-release system on the existing pipe – anywhere on a straight run.

  2. Quick-release lever of the VC 600 clamp

    Close the clamp

    The two levers clamp the system to the pipe quickly and firmly. The pipe stays closed and pressurised.

  3. Inserting the VC 600 measuring unit into the clamping system

    Insert the measuring unit

    Place the measuring unit in the clamping system – without touching the medium or interrupting operation.

  4. Fastening the VC 600 measuring unit with a screwdriver

    Fasten with a screwdriver – done

    Fasten the measuring unit with a screwdriver, enter the pipe diameter on the display and check the signal quality. The VC 600 is measuring.

VC 600 on four pipes of different diameters

One measuring unit for every diameter

The universal measuring unit fits all clamping systems from Ø 25 to Ø 90 mm. For another pipe you only change the clamping system.

  • 10 clamping system sizes (A20 … A100), larger diameters on request
  • Steel, stainless steel and aluminium; wall thickness 1.5 … 5.0 mm
  • Compressed air, nitrogen and other gases
VC 600 touchscreen showing flow, consumption, velocity, temperature and pressure

Commissioning without a manual

The touchscreen guides you through three steps: enter the pipe dimensions, check the signal quality and set up the outputs. You can do all of it from your phone too.

  • Signal quality on the display: SNR, signal strength, signal quality, velocity
  • Free CS SensorApp (iOS/Android) via Bluetooth
  • Remote service support straight from the app

Installation is possible at any time during operation: no work on pressurised pipes, no need to open the pipe – and therefore no pressure limitation.

Why Clamp-on?

90 % faster installation

Fit the clamping system, fasten the measuring unit – done. No pipework and no planned shutdown.

100 % process reliability

Non-invasive: no drilling, no welding, no risk of contamination. No need to re-certify the compressed air quality after installation.

100 % safety

No work on pressurised pipes and no need to open the pipe – so no pressure limitation. Installation is possible at any time during operation.

100 % leak-free

No seals and no direct contact with the process.

0 % energy loss

The measuring unit causes no differential pressure in the gas flow and creates no leaks.

Wider measuring range

0.08 … 20 or 25 m/s – far more than standard clamp-on sensors. Suitable for leak measurement and very high flow rates, with an extremely fast response.

Touchscreen and CS SensorApp

Set up and read the sensor on the display or via Bluetooth with the free iOS and Android app – even at hard-to-reach points.

Consumption and leakage analysis

Built-in 50 MB data logger: consumption and leakage profile over the last two years (10-minute interval), export as CSV or PDF.
