Gebruik de PSET-QF of PSET-PVC-set om het drukverschil te meten;
(2)
Om het debiet van de luchtstroom te meten met gebruik van PSET-PTx, geef het doorsnede-oppervlak van de buis \ [cm²] in Modbus-register 35. Om het debiet van de
luchtstroom te meten met gebruik van PSET-GF of PSET-PVC, geef het doorsnede-oppervlak van de buis \ [cm²] in Modbus-register 30.
(3) Gebruik de PSET-PTx-set om luchtsnelheid te meten.
