Description

Teledyne Hastings Instruments products represent over 60 years of experience in the design and manufacture of gas flow instrumentation. The high flow meters and controllers featured in this document are based on the 300 Series line of flow sensors. The 300 Series transducer is a patented thermal-based flow sensor designed to provide exceptional linear response to changing flow rates. The electronics associated with the sensor are precisely tuned to give fast response time.

The flow transducer is combined with a laminar flow element to configure the flow meter for the customer. In many flow meters, the major source of error is the non-linearities that occur in the laminar flow element due to entrance and exit effects. However, the 300 Series laminar flow element is designed such that the flow sensing region is far less susceptible to these effects.
