Meter selection guidelines
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.
- If the chosen metering section is smaller than the pipework in the installation, the connecting pieces should be tapered.
Meter sizes
The PD 340 Flow Transmitters are available in the following 6 sizes:

(1") | 8 m3/h |
| C 38 |
(1½") | 20 m3/h |
| C 51 | (2") | 40 m3/h |
| C 63 |
((2½") | 80 m3/h |
| C 76 |
(3") | 120 m3/h |
| C 102 |
(4") | 200 m3/h |
- * MUST NEVER BE EXCEEDED
