Field of application

The Flowfit CPA250 flow assembly is designed for pipe installation in water and wastewater treatment. It offers space for three sensors and is able to extend their service life by keeping them wet even when the flow is interrupted. The assembly itself is also durable thanks to corrosion-resistant polypropylene. With Flowfit you get the right product exactly for your standard applications.

Flowfit CPA250 is intended to be used in pipes in:

Wastewater treatment
Drinking water
Utilities

It is suitable for use with pressures of up to 6 bar.

Benefits

Cost-efficient flow assembly for in-line installation
Simple installation and removal of the sensors thanks to threaded cap
Easy calibration without dismounting the sensors using the removable bottom part as calibration vessel
Reduces installation effort by providing 3 mounting positions for 120 mm sensors or an optional cleaning unit
