Level and flow specialists Allison Engineering has extended its KTEK range of laser based instruments with the 2D volume flow scanner and a 3D laser belt scanner.

These devices offer high accuracy, non-contact and continuous measurement.

The KTEK LM080 laser belt scanner provides continuous, non-contact m3/h volumetric flow measurement of bulk solids lying on belts and conveyors, whilst simultaneously monitoring the belt speed.

The result is a 2D cross-sectional area of bulk material, while the belt speed provides a 4-20mA output which is scaled in m3/min.

Unlike other volumetric measuring technologies, such as gravimetric weighing, Allison told manufacturingtalk that the KTEK laser belt scanner is unaffected by vibrations and so provides more accurate data.

It provides accuracy of +/-2% and is quick and simple to set up.

It requires no regular maintenance or re-calibration.

The LM080 is a rugged and competitively priced device which is particularly suited to volumetric measuring applications wherever bulk solids and granular materials are being conveyed and stored.

* Moving 3D laser scanner - the KTEK LM050 is a moving 3D laser scanner which provides continuous, non-contact three dimensional measuring, or 'mapping' of entire stockpiles.

Each laser uses a large number of measuring points to ensure accurate profile imaging and automatic volume measurement to an accuracy of +/-0.5%, said Allison.

This device meets the increasing demand in industries where users are moving toward increased automation of production and inventory control, for example in power stations or wherever bulk solids, such as coal and aggregates are stockpiled.

Benefits would include enhanced environmental control and the ability to provide improved fiscal valuation of bulk solid stocks and therefore more accurate estimates of available 'energy stock'.
