Flow restrictor with strainer insert

Flow restrictor with strainer insert

What is it used for?

The flow restrictor with strainer insert is installed upstream of the analyser in the sample-water inlet and performs two tasks at once: it limits the flow of the sample water to a device-appropriate level and, via the integrated strainer insert, holds back foreign matter and suspended solids. This ensures that only clean, evenly flowing sample water reaches the measurement.

Why does this matter?

Online analysers deliver the most reliable results when the sample water is supplied under conditions that are as constant as possible. A flow that is too high or strongly fluctuating can distort the measurement, and particles in the water can clog sensitive components or wear them out prematurely. The flow restrictor with strainer insert intercepts both at a single point – protecting measuring accuracy and the device at the same time. This makes it a small but effective component for low-fault continuous operation.

Benefits at a glance

• Flow limitation and dirt filtering in one compact component
• Protects the analyser from foreign matter and suspended solids
• Ensures even, device-appropriate flow conditions
• Contributes to stable, reproducible measurement results
• Designed for an inlet pressure of up to 4 bar
• Low-maintenance – the strainer insert can be cleaned when needed
