VacuMed has developed an ultra linear orifice flow sensor and supporting electronics specifically for a variety of precision uni-directional and bi-directional gas flow measurements in the medical and research field. The rugged flow meters are designed for high reliability and simplicity of use. Product benefits include wide measuring range, small deadspace, low resistance to flow, no zero or gain drift, and low sensitivity to gas concentration changes. The flow sensors are available in 3 standard sizes: Low-low, low and medium. Custom versions available on request.
