4. Installation
4.1. Location
Different pipe configurations and obstacles in the flow line such as valves, elbows, pipe
bends and strainers create variations on the flow profile.
Whenever possible follow the EN ISO 5167-1 installation recommendations to locate
the sensor.
Always maximize distance between flow sensor and pump.
