MEASURE TO MANAGE
1.5 Using the Flow Meter
Do not use this product in explosive areas.
Do not exceed the permitted operating parameters. Any operation exceeding
these parameters can lead to malfunctions and may lead to damage on the
instrument or the system.
Do not exceed or go below the permitted storage and operation temperature
and pressure.
This product should be maintained and calibrated frequently, at least every
2 years.
1.6 Storage and transportation
Make sure that the transportation temperature of the sensor is between
-10°C to 60 °C.
Storage temperature of the sensor is between -10 °C to 50 °C and the
humidity is <90%, no condensation.
Avoid direct UV and solar radiation during storage.
Section 2 : About WAFS -103 Differential Pressure Pitot Tube Flow Meter
2.1 Importance of Flow Meters:
Flow meters are very popular for measuring compressed air systems. Depending on
where they are installed, flow meters can tell you the compressor output, system consumption,
peaks and troughs as well as average usage. When used well, flow monitoring can help keep
your system under control and highlight any unusual activity in your system.
Benefits of Monitoring Flow Include:
Improves system efficiency
Reduces system maintenance
Reduces operating and energy costs
Increases system understanding and operation
Identifies changes in system performance
Identifies non-productive air demand and leakage
Identifies peak and average demand
Different types of flow meters should be used depending on the specific location and
purpose. However, when it comes to compressed air, flow meters such as vortex or orifice plates
can create a pressure drop within the system, ultimately leading to increased operating cost of
the entire plant. As such, vortex or orifice plate flow meters are not recommended for
compressed air.
