KROHNE FLEXMAG 4050 C Flowmeter
Overview
KROHNE FLEXMAG 4050 C Flowmeter
Accurately measure your fluid flow rate with the KROHNE FLEXMAG 4050 C® electromagnetic flowmeter to safeguard your process.
Other flowmeters using ultrasonic technology are dependent on fluid properties such as pressure, temperature and viscosity. Due to the electromagnetic principle and the manufacturing precision of the flow tube, the FLEXMAG flowmeter provides highly accurate measurement with outstanding repeatability. It provides a completely stable, direct and accurate fluid flow measurement that will not drift over time.
The flowmeter features a disposable, biocompatible and gamma sterilisable flow tube that easily integrates into customised single-use assemblies. It is one of a wide range of product accessories and is compatible with:
- WMArchitect single-use assemblies
- PROFINET® and EtherNet/IP™ 530, 630 and 730 series Watson-Marlow process pumps
This flowmeter is available as a package with Watson-Marlow pumps and/or WMArchitect assemblies.
Features and benefits
- Electromagnetic flowmeters provide superior accuracy and repeatability
- Verify accurate flow conditions of compatible Watson-Marlow pumps
- Enable easy integration into customised WMArchitect single-use assemblies to ensure product quality
