Clamp-on flow sensor

KROHNE has added a new sensor variant to its product range of clamp-on ultrasonic flowmeters for measuring liquids: the new OPTISONIC 6300 XT for high temperature applications. It allows non-intrusive measurement of fluids with temperatures up to 200 0C or 392 0F.

The sensor and connection box of the OPTISONIC 6300 XT are made out of stainless steel, special transducers are integrated in the sensor construction, and a protection sleeve for the signal cable is provided to prevent damage from hot pipes. The OPTISONIC 6300 XT is available in two sensor types; small and medium, for diameter sizes DN 15 to DN 400.

Target applications and markets for the OPTISONIC 6300 XT include heated hydrocarbons, molten sulphur, thermal oil, heat traced MDI, carbamate in the petrochemical and chemical industry, hot water for district heating and condensate in the energy industry and CIP/SIP processes in the food and beverage and pharmaceutical industry. In these applications, OPTISONIC 6300 XT offers many benefits as it is easy to install, increases safety and provides accuracy and reliability.

Easy installation
The OPTISONIC 6300 XT can be installed on heated and insulated pipes without the need to cool down or shut down the process, saving substantially on installation costs. The innovative construction of the OPTISONIC 6300 is one of the key distinctive features enabling an immediate startup within 15 minutes without the need for a specialist, training or special tools. Special XT transducers are integrated in the sensor construction and the sensor itself can be easily fitted onto a pipe with its fixing units. A signal strength indicator on the converter display helps to choose the optimal position for the transducers.

Safety first
Many high temperature applications demand safety precautions to be taken. Not having to cut the pipe for the installation of a flowmeter improves the safety of the process and more importantly the safety of the people installing the meter. In addition, a clamp-on measurement limits potential leakage points.

Reliable and accurate measurements
The OPTISONIC 6300 XT has a highly robust clamping mechanism suited for industrial use. The instrument monitors fluid anywhere, regardless of high liquid temperatures, pipe sizes, or pipe material with or without a liner. The tight and robust 316L screw connection of the signal cable to the stainless steel sensor can be positioned at any angle between 0 and 45 Degrees. The system withstands harsh environmental conditions and can be applied in hazardous areas as it is approved for use in ATEX Zone 1.

Easy maintenance
Regreasing has never been as simple, safe and efficient as with the OPTISONIC 6300 XT and can be done in just a few steps, minimizing maintenance time. Because the transducers are integrated in the sensor construction, they are placed back at the exact same position as before and there will be no deviations in the measurement results before and after regreasing.
