DESCRIPTION
DPT-Flow
Air Flow Gauges
Each device is individually temperature compensated. Each device has autozero element which makes it fully maintenance free.Supported FAN manufacturers: Fläkt Woods, Rosenberg, Nicotra, Comefri, Ziehl, Ebm-Papst, Gebhardt
**) including: general accuracy, temperature drift, linearity, hysteresis and repetition error

MENU selections and initialisation instructions for installation
If buttons are not pressed within 20 seconds the device returns to the normal measuring mode.
1. Press Select > 2seconds to start the menu.
2. Selection of the manufacturer of FAN
3. Each FAN has its own specific K-value.
Please see the right K-value from the datasheet of the FAN:
Fläkt Woods (k=0,3…99), Rosenberg (k=37…800), Nicotra (c=10…1500), Comefri (k=23…158), Ziehl (k=10…1500), Ebm-Papst (k=10…1500)
4. The unit shown on the display m³/s, m³/h or Pa
5. Output unit for defining the output scale
6. Output scale, selectable range depends on the chosen output unit.
m³/s 10V = 5…50 m³/s
m³/h 10V = 20 000 … 200 000 m³/h
0 V is always 0 m³/s and 0 m³/h
7. Stepless response time selection.
Tr can be selected to be 1 s … 20 s.
Tr is the time when output has changed 63 % from the final value of the output.
8. Press send and the device returns the normal measuring mode

Auto zero element
Auto zero element makes the DPT FLOW meter maintenance free. Element automatically adjusts the transmitters zero point from time to time, this eliminates the zero point long term drift of the piezoresistive sensing element.
During zero point adjustment the output and display values will freeze to the latest measured value. The automatic zero point adjustment takes 4 seconds. Zero point adjustment is carried out every 10 minutes normally and during warm up the time is shorter a few times.
The display can be ordered separately for installation purposes.
