INSTALLATION
The minimum upstream (10 x D) and downstream (3 x D) distances must be
observed.
Flow direction
Please ensure that the pipe design does not allow the build up of air
bubbles or cavities within the medium as this will cause measuring errors.

Measuring flow direction:
The measuring flow direction depends on the mounting direction of the transmitter. To
inverse the measure turn the transmitter 180° on the fitting for a positive flow direction
ensuring that the lug is in the upstream direction (see Fig. 3.1). The flow display is
always positive but the totalizers increase or decrease depending on the flow direction.
