The AMF quick release holder in conjunction with the Dixon optic overfill sensor was developed to transport hazardous goods as per ADR, SANS and European Standards. Designed with ease in mind for the operator the AMF quick release holder eliminates the twisting of signal wires when the optic sensor needs to be removed either for service or safe keeping (to be used in conjunction with the AMF external holder) when the tanker barrel needs to be washed or steamed in the wash bay. The quick release holder can be supplied with a variety of sensor extension bushes depending on the filling level of tanker and/or product. The AMF quick release holder must be used in conjunction with the Dixon FT100S optic overfill sensor.
