5.6 Influence of flow velocity
As an indication and averaging of different internal and external tests Sintrol Instruments with Inductive
Electrification Technology show the uncompensated Influence of flow velocity as follows:
Figure 4 Influence of Flow velocity
On the S304 you have the possibility to connect the mA output signal of flow meter. This signal is used by the
S304 for compensation. The influence of flow velocity is then as follows:
The flow behaviour may vary depending on the dust material, the particle size, the
temperature and the installation location.
The minimum flow velocity is recommended to be 3m/s
Maximum tested flow velocity is 40m/s
5.7 Special dusts
Sintrol Products with Inductive Electrification Technology react properly to almost all dust materials.
The only known exception is heavy metal dusts where the behavior is known to be challenging. For measuring
such dusts, the S303 or S304 needs to be specially tested beforehand.
