4.5.2 Pulse Output Mode
The pulse output mainly applies in count mode. A pulse output delegates a unit flux,
such as 1l or 1m
3
etc. The pulse output unit divides into 0.001l, 0.01l, 0.1l, 1l, 0.001m

. When users choose the pulse unit, the match of the flux range of
flow meter and pulse unit should be noted. For volume flux, the count formula is as
follows:

Note:
D is the diameter of the nozzle (mm)
V is the velocity of flow (m/s)
4.5.3 The Connection of Digital Output
Digital output has two connected points: digital output connected point, digital
ground point, with the following symbols:
P
OUT
- digital output point
P
COM
- digital ground point
4.5.4 Digital Output Connection as Photoelectric Coupling (PLC etc.)
Commonly, the user’s photoelectric coupling current is about 10 mA, so E/R=10 mA,
where E=5 to 24V.
