4.2.13 EQ LTE™ flow logger
Note:
The location of the air flow sensor may
vary according to the compressor, compressor
array or the process parameter being
monitored
Safety:
The flow sensor measures the flow velocity
using the calorimetric principle in the middle of
the pipe. Please observe mounting instruction:
•
L: Length of pipe section
•
At inlet (L1): 15 x inner pipe diameter
•
At outlet (L2): 5 x inner pipe diameter
•
D: Inner diameter of pipe wall
Warning:
Do not exceed the pressure range of 50bar!
Pressure is a hazard! When installing and
removing the sensor and where the operating
pressures in and around the position of the
sensor are greater than 10 bar g, we
recommend the use of elevated protection
measures prescribed by local, regional,
national or internationally reputable
organizations. If in doubt, do not proceed!
Overheating destroys the sensor.
Observe the permissible storage and
transportation temperature as well as the
permissible operating temperature.
Always observe the direction of flow when
positioning the sensor!
The safety ring at the sensor head must
always remain undamaged and rest correctly
in its installed position.
The screwed fixture must be pressure tight.
The adapter sleeve must be tightened with a
torque of 20 to 30 Nm.
Avoid condensation or water droplets at the
sensor element. Condensation or water on the
sensor element may cause a fault and may
corrupt sensor data.
The size of the inlet and outlet pipe diameter
sections must not be less than the specified
minimum values. Failure to observe may
increase deviations in the measured data.
The manufacturer cannot be held liable for any
damage which occurs as a result of non-
observance or non-compliance with these
instructions.
Should the device be tampered with in any
matter other than a procedure which is
described and specified in the manual, the
warranty is cancelled and the manufacturer is
exempt from liability.
The device is supplied exclusively for the
described application
