Hot flow

Non–intrusive flow measurement in hot applications

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 for a non-intrusive measurement of fluids with temperatures up to 200°C or 392°F.

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

Target applications and markets for the unit 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 it 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 a process. This saves substantial installation costs. The innovative construction of the OPTISONIC 6300 is one of the key distinctive features enabling an immediate startup within 15 minutes. It does not require a specialist, nor training and no special tools to do so. Special XT transducers are integrated the sensor construction. The sensor can be easily fitted on a pipe with its fixing units. A signal strength indicator on the converter displays helps to choose the optimal positions of 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 under a movable angle. 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
Minimal maintenance time is guaranteed with its easy (re-)greasing concept. Regreasing has never been so simple, safe and efficient as with the OPTISONIC 6300 XT and can be done in just a few steps. Because the transducers are integrated in the sensor construction, they are placed back at exact the same position as before and there will be no deviations in the measurement results before and after regreasing.

IR Temp

New infra-red temperature sensor with RS485 Modbus interface

Calex has an innovative new range of compact infra-red pyrometers with built-in digital communications for easy systems integration

The new PyroBus series is designed to measure the temperature of inaccessible or moving objects and materials, from -20°C to 500°C, accurately and consistently, with an outstanding response time of 240 ms.

The built-in RS485 Modbus RTU interface provides the maximum, minimum, average and
instantaneous temperature of the material or process being monitored. It also provides the internal temperature of the sensor to ensure that each one is being operated within the correct ambient temperature limits and so prevent damage caused by overheating. Users can adjust the emissivity setting for each sensor, compensate for reflected energy, apply filtering to fluctuating temperatures and use peak or valley-hold processing to measure hot or cold objects on conveyors. Up to thirty
two sensors can be installed on a single multi-drop network.

All PyroBus sensors are fitted with precision Germanium lenses for accurate optics. Model PB21 has 2:1 optics making it suitable for most applications where the sensor can be mounted close to the target. Model PB151 is designed for small or distant targets and has an optical resolution of 15:1. Model PB301 is designed for very small or distant targets and has an optical resolution of 30:1.

Each sensor is just 18 mm diameter by 103 mm long and is made of polished stainless steel, sealed to IP65, making it ideal for food and pharmaceutical applications. It is held in place by a mounting nut (included). Fixed and adjustable brackets are offered to simplify mounting and a laser-sighting tool is available to assist in the sighting of the sensor.

If the sensor is required to operate in a very high or low ambient temperature (less than 0°C or more than 70°C) it can be ordered with a water/air-cooled jacket built around it.

For dusty environments, such as in paper or textile mills, an air-purge collar can be fitted to keep the lens clean.


High-spec CTD logger

The new OTT CTD is a professional datalogger for the measurement of water level, conductivity and temperature. With a memory capacity of 4MB (approx. 500,000 values) and capable of running on alkaline or lithium batteries, this high-specification instrument is capable of operating unattended for long periods.

Primarily designed for groundwater applications in wells from one inch diameter upwards, this instrument is equally well suited for surface water monitoring.

The water level measurement technology employed by the OTT CTD is robust and well-proven with thousands of loggers, such as the Orpheus Mini, currently in operation world-wide.

The inbuilt conductivity measuring cell can also provide data for salinity and total dissolved solids. Designed to meet the demands of a rugged field device, it meets all the requirements of hydrological data collection in saline and other challenging environments.

In order to provide reliable long-term monitoring data, high specification materials have been included in the OTT CTD design. These include a ceramic pressure sensor, high quality stainless steel housing (904l) for durability and corrosion resistance and a kevlar-strenghtened probe cable with an integrated compensating capillary tube.

The infrared interface facilitates quick and easy data collection, and simple, intuitive software is included for data display, export, configuration and calibration. A pump test facility is also included as standard.

Wireless data transmission of remote data is made possible with the addition of the OTT ITC which employs GSM/SMS or GPRS.
Commenting on the launch, OTT UK Managing Director Simon Wills said, "This new high specification instrument has been designed for people who need the most accurate and reliable technology, so we anticipate that the main customers will be regulators, water companies, consultants and researchers."

Flying probe

The true integration between ATE flying probe and boundary-scan test

Aiming to further enrich its range of solutions for the test and repair of electronic boards, Seica, in partnership with Temento Systems, has developed the FlyScan module as a new approach to the integration of the boundary scan technique and flying probe test systems. The true innovation of FlyScan, is today available on the complete line of Pilot/Aerial flying probe testers, it’s full integration at the core system level, ensuring the following capabilities at a competitive price:
    • Automatic generation of the test program in a single software environment (Seica VIVA)
    • Automatic creation of the boundary scan program also for nets which are not of the JTAG type, using the “extended test” function and the flying probes to transform them into “JTAG testable” nets
    • Automatic elimination of test redundancies
    • Automatic fault diagnostics, with real-time generation of additional tests executed by the flying probes for the specific identification of the faulty component.
    • A single test report in the VIVA environment
    • Management of the faults detected by the boundary scan test in the Seica Repair Station environment
Even though its development and integration is the result of a significant investment in R&D, the basic idea of the FlyScan module is very simple: it exploits the specific benefits of flying probe and boundary scan testers, creating a single test program which utilizes the full capabilities of both, not as two entities working independently, but in a fully integrated system.

Compared to the classic approach where a board is subjected first to a standard flying probe test and then to a boundary scan test on a separate test station, the core interaction between the worlds of flying probe and boundary scan test enabled by the Seica FlyScan module provides a decidedly improved test result, easily measurable in terms of speed, throughput and fault coverage.

FlyScan is now available on all Seica’s Pilot/Aerial flying probe systems, from the entry-level Aerial M2 right up to the top of the range Pilot V8.
