STEP 2: WIRING DIAGRAMS
For CE compliance, a properly grounded shielding cable is required.
1) Unscrew the strain relief and route the cable.
2) Connect the wires as shown in figure 2a and 2b.
3) Tighten the strain relief.
Figure 2a - Wiring diagram: Volume flow output
0–10 V / 4–20 mA
+ Power supply
24 VDC / 24 VAC
Figure 2b - Wiring diagram: Pressure output
0–10 V / 4–20 mA
+ Power supply
24 VDC / 24 VAC
STEP 3: CONFIGURATION
1) Select the functioning mode of the flow meter:
- Select Manufacturer when connecting DPT-Flow to a fan
with pressure measurement points
- Select Common probe when using DPT-Flow with a
q = k ∙ √∆P (i.e. FloXact)
common measurment probe that follows the formula:
MANUFACTURER
Common probe
Common probe
2) If Common probe selected: select measurement units used in the
formula (aka Formula unit) (i.e. l/s)
FORMULA UNIT
l/s
3) Select K-value
a. If manufacturer selected in step 1:
Each fan has a specific K-value. Select the K-value from fan manu-
facturer's specifications.
Manufacturer: K-value:
Fläktwoods k = 0,3...99
Rosenberg k = 37...800
Nicotra k = 10...1500
Comefri k = 10...2000
Ziehl k = 10...1500
Ebm-papst k = 10...1500
Gebhardt k = 50...4700
