Our Respiratory Flowheads have a number of benefits:
- Lightweight design
- Low thermal inertia
- Direction sensitive
- Low costs
Each of the flowheads has been designed to change the applied flow to a stream of laminar airflow, which is then applied to a very fine stainless steel gauze assembly. This acts as a resistive element to the airflow, and within the rated levels of each flowhead, produces a pressure differential proportional to that airflow.
The pressure differential is very small, and when connected to a differential pressure transducer, allows a direct reading of both positive and negative flow rate. G M Instruments can advise on the availability of suitable transducers.
