Radar Gauges Boost Raw Materials Level Measurement
Following successful trials that demonstrated a marked improvement in production efficiency, industrial plastics manufacturer Schwartz has chosen to install two Krohne Optiwave radar level gauges.
Keeping a steel melting arc furnace cool
Eight electromagnetic flowmeters measure the critical flow of cooling water in a 50 tonne electric arc furnace to ensure the correct operation of the cooling system.
Radar level meter improves accuracy
Krohne's Optiflex 1300 TDR radar level meter has been installed by Deza to improve the accuracy and reliability of naphthalene measurement.
Schwartz, which is based in Germany, is one of Europe's leading manufacturers of plastics components which are used in industry worldwide.
Through using Krohne's Optiwave instruments the company has significantly improved level measurement accuracy of raw material which is kept agitated in containers prior to processing.
Schwartz manufactures its products from polyamide, which is a plastics made from processing a raw material called caprolactam.
During production, caprolactam, which has a density similar to water, needs to be heated for it to remain liquid - at room temperature the substance will harden.
Before processing, it is stored in relatively small, two meter high containers where it is maintained at 120 deg C.
The containers are fitted with agitators which, because of the turbulent surface they create on the liquid, make it difficult to accurately monitor the precise level of material in the tanks.
Previously the company used float-type devices which led to unreliable measurement readings being taken.
Krohne's Optiwave radar level gauges are capable of measuring to an accuracy of +/-3mm, despite the uneven liquid surface.
Their relatively small antennas and high resolution measurement frequency make them ideally suited to applications involving small containers and turbulent surfaces.
The Krohne Optiwave also has a pre-programmed 'Agitator Tank' option, which can be selected via its 'quick setup wizard' menu.
By using this function, the instrument will automatically compensate for fluctuations in level readings to provide accurate measurement output.
"We are really satisfied with these two Krohne Optiwave units because they let us detect the filling levels in our tanks with far more accuracy than was previously possible," said Ulrich Kottkamp, works manager at Schwartz.
