PFMB is a digital flow sensor compatible with air and nitrogen. Its thermal sensor is protected in a bypass flow path to reduce contact with moisture and contaminants, avoiding accuracy deterioration and damage. Dimensions and weight have been reduced dramatically compared to the legacy PF2A. The 4-digit LED display can be red or green, changing when a set point is reached. Either instantaneous or accumulated flow can be shown. Options include cable connector type, and bracket mount. Two outputs are available, including two switch signals, or a switch and analog signal. PFMB is IP40 rated, and CE and RoHS compliant.
