The OPTISONIC 6300 is an ultrasonic clamp-on flowmeter for permanent mount installation. It is particularly suitable for flow measurement of (non-)conductive liquids at any location where inline measurement is not possible or desirable. The flowmeter consists of a combination of one or two clamp-on sensors and one ultrasonic signal converter. Its robust clamp-on rail is highly flexible and can be very easily attached to virtually any pipe up to DN4000 / 160".
