Teledyne Hastings Instruments products represent over 70 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. This sensor is designed to provide exceptional linear response to changing flow rates. In addition, 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...
