When selecting the meter size please observe the following guidelines:

– As a main rule, a Flow Transmitter with a pipe dimension equal to the rest of the piping system should be selected.

– Never exceed the maximum flow rate of the transmitter (see below).

– If optimum measurement accuracy is primary concern, the smallest possible transmitter should be chosen, still observing that the maximum flow rate must under no circumstances be exceeded.

– To further improve accuracy, especially on very low flow rates, the Linearizing function should be enabled. Please refer to the manual for details.

– If the chosen metering section is smaller than the pipework in the installation, the connecting pieces should be tapered.
