Industry: Mining Coal
Location: NSW Australia
Media: Coal Fines- Magnetite
The Application: Coal Mine - Magnetite
A coal mining site required flow measurement of a mixture of coal fines and magnetite through chromium and stell, rubber lined pipes. Due to the high abrasive process slurry combined with highly corrosive chemicals a clamp on non-instrusive flowmeter was tested. Process solids varied from 20% up to 50%. The flow included a large concentration of MAGNETITE. Lack of suitable meters prevented proper process control on the plant. During a flow survey conducted on the site most of the existing slurry lines were measured within a few hours.
FLOWSERVICES installed a portable high power CompuFLow Doppler flowmeter and consistent and accurate flow reading were achieved with minutes.
Problem Solved!
The flow could not be stopped and the meter had to be installed on a 'live' pipleline.
The process slurry contained high concentration of MAGNETITE
A portable CompuFLOW ultrasonic Doppler-clamp on flow meter was installed without cutting the pipe.
The test site sensors were attached with simple straps for quick removal and simple re installation.
The meter provided accurate data allowing management to justify purchase of fixed Doppler flowmeters
Process engineers were able to control production and rely on accurate flow meter results.
