Bypass Set-up
When used in a bypass set-up, as illustrated below, the D6F-P
mass flow sensors can measure flow rates far beyond the 1
LPM in-line rating. The pressure differential required to pull
airflow through the sensor can be accomplished by installing a
flow restrictor between the two ports or through the use of a
flow cross in large ducts, as shown in the HVAC application.
HVAC Application
The D6F-P mass flow sensor is ideal for
damper control in variable air volume
systems, where low flow rates are
difficult to measure with differential
pressure sensors.
Precautions
1.
Avoid use in excessively dirty, wet environments
2.
Do not use in the presence of flammable gases (e.g.
hydrogen, methane, ethane) and liquefied petroleum gas. In
addition, do not use with corrosive gases (e.g. chlorine, sulfur,
acids, alkalis, etc.).
3.
Install so that gas flows from “+” to “-” stamped ports.
4.
For best results (optimum accuracy), mount horizontally.
5.
Use 2 suitable M2.6 screws for mounting. Do not exceed a
fixing torque of 0.59 Nm.
6.
Do not modify D6F- in any way.
7.
Do not place any object in or close to the inlet and outlet
orifices.
8.
Do not use the sensor in any of the following environments:
•
a location that receives significant radiant heat
•
a place where intense light may radiate down
•
where fast changing temperatures occur
•
locations prone to freezing, high humidity, condensation
•
where large magnitudes of vibration or shock could occur
9.
Noise countermeasures: VERY IMPORTANT: Take suitable
precautions to minimize the effects and potential for induced
electrical noise. Install away from apparatus that generates strong
high frequencies, surges and spikes. Take particular care to
install away from AC power transformers, live mains power lines
and high power magnetic circuits. Attach a surge suppressor and
a noise filter to the peripheral equipment.
10.Ensure
good grounding is achieved by grounding the GND
terminal to the peripheral equipment’s main ground frame
connection and its associated regulated power supply.
11.Do
not make a direct solder connection to the integral
terminals on the connector model type. The use of optional cable
‘D6F-CABLE2’ is recommended for attachment to ensure correct
connection (D6F-P0010A2). Solder PCB terminals after securing
the sensor to the board (D6F-P0010A1).
12.D6F-
is a precision component. Keep in original packaging
and remove only when ready for installation. Damage may occur
if subjected to excessive force (e.g. dropped or kicked). Any item
suspected to be damaged should be discarded.
13.Immediately
following installation, a qualified person should
perform checks to ensure safe, satisfactory operation.
