Location in the system

The optimum location in the system depends on the application:
● Liquid applications
Gas or vapor bubbles in the fluid may result in erroneous measurements, particularly in the density measurement.
– Do not install the flowmeter at the highest point in the system, where bubbles will be trapped.
– Install the flowmeter in low pipeline sections, at the bottom of a U-section in the pipeline.
Figure 3-1 Liquid applications, wrong location with trapped air/gas
● Gas applications
Vapor condensation or oil traces in the gas may result in erroneous measurements.
– Do not install the flowmeter at the lowest point of the system.
– Install a filter.

Flow direction
The calibrated flow direction is indicated by the arrow on the sensor. Flow in this direction will be indicated as positive by
default. The sensitivity and the accuracy of the sensor do not change with reverse flow.
The indicated flow direction (positive/negative) is configurable.
