NOTE
•
The gas flow velocity is usually much higher than liquid when measured by a flow
meter, so there is noise caused by gas medium and tube wall of flow meter
under a high-speed gas flow and if the noise becomes loud enough, the signal of
flow meter will be influenced, so use the Tek-Cor 1100A Coriolis flow meter for
gaseous medium at velocity less than 1/3
rd
of the sound velocity (360 fps).
•
Use Tek-Cor 1100A for gas with a pressure less than 29 PSI (0.2 MPa).
