FLOW MEASUREMENT

ROUND UP

Precise measurement of consumable fuels in automobile industry

First reasonably-priced camera package with 90° lens

The Optris PI 640 thermal imaging camera launched onto the market in 2014 is avail- able with two additional changeable lenses.Three lenses with 33°, 60° and 90° fields of view are now available for different measuring tasks and customer requirements. “With this offer, we are launching the first reasonably-priced VGA thermal imaging camera with a 90° lens”, explainsTorsten Czech, Product Marketing Manager at Optris (represented in South Africa by Instrotech).The offer includes both calibration and open source software. The Optris PI 640 is used in different industries worldwide. Many applications offer very little space between the measured object and the thermal imaging camera.This is where IR users require greater flexibility.The proprietary software also enables the use of the thermal imaging camera as a line scanner, allowing it to reach a scanning angle (Field Of View, FOV) of up to 120°. Developed, manufactured and calibrated in Germany, the lenses have unique components, including the germanium lenses typically used in the longwave infrared range (LWIR), where each respec- tive lens is calibrated for the thermal imaging camera.

KOBOLD Instrumentation, represented in South Africa by Instrotech – a Comtest Group company, was asked to look into, and supply a solution to an ongoing headache for an established Japanese automotive company – how to accu- rately record the exact quantity of fuel received on-site, daily. In order to track every single part and con- sumable needed to get the 28 000 cars this manufacturer producesmonthly, up and running, it goes without saying that the logistics depart- ment’s records have to be highly accurate and instantly accessible. One of the most important consumables is fuel, both gasoline and diesel. These fuels are not only used for car testing, but also for utility purposes like fork-lifts, emergency electric generator, inter-plant transportation, etc. The flow and level metering of the fluids, had always been of concern to management. The automotive company routinely purchases fuel, which arrives at the plant site by fuel truck. It is unloaded and stored in several dedicated storage tanks.The existing gear flowmeters had been running for more than 10 years and the operation was handled by a single field operator, using simple log book. The level meters were even more traditional, using only mechanical floats and simple on-the-tank-side scale. KOBOLD proposed using their TME coriolis mass flow meters and NMC capacitance level transmitters, integrated with a PC-based central- ized data acquisition unit, to be located in the Logistics Room.

The open source soft- ware included, is free of charge with the de- livery. Optris offers a discount on the cost of adding another lens to a thermal imaging camera including cali- bration. Enquiries: Tel. 010 595 1831 or email sales@instrotech.co.za

Ultrasonic heat and cold measurement for water Instrotech representing, ELIS PLZEN, Czech Republic manufacturer and supplier of flow meters, has on offer the SONOTHERM 3070 – an ultrasonic heat and cold meter intended for measuring absolute heat/cold quantities delivered to plants or otherwise consumed in closed hot-water heating/cooling systems. When used as a commercial meter, the SONOTHERM 3070 can be located either at the input hot-water piping to heated buildings or premises, or at the output of heat sources ahead of a heat exchanger. The SONOTHERM heat/cold meter measures and stores information on heat quantity calculated from the water temperatures measured at the input and output

piping by means of coupled resistance temperature sen- sors Pt 100 (Pt 500).The heat- ing/cooling water flow-rate is measured by ultrasonic flow meter. It has a temperature range of 0 to 150°C with a Min.Temp differential of 2°C and a flow-rate range of 0,05 to 23 000 m 3 /h. Enquiries:Tel. 010 595 1831 or email sales@instrotech.co.za
