The Endress+Hauser Promass 83 coriolismass flow meter will accurately meterflotation frother liquids or tank agitationgases and control dosing pumps at 0.1 %accuracy. The meters simply bolt in to theprocess pipe line and are available withmany industry standard DIN and ANSIflanges and are designed to operate up to
very high process pressures and cold or hot temperatures (400 bar and -50 to +200 C/5800 PSI and -58 to 392 F).
All Endress+Hauser meters are available with a range of industry standard com-munications protocol such as HART ,PROFIBUSPA/DP or Foundation Field-bus.
As many recent mine accident reports haveshown Xanthate is an extremely flammablereagent and Endress+Hauser pH sensorsand meters come with appropriate hazar-dous area class approvals such as ATEX, FMand CSA.

Endress+Hauser are the worlds largest producer of pH electrodes and have beensupplying the mining industry for over 50
years. New sensors now come with uniqueMemosens technology which is quick plug
watertight cable with integrated electronics which stores laboratory pH and temperaturecalibration details. This means that brokensensors can be replaced and the new sensordoes not need to be recalibrated.
pH sensors with Memosens technology store the actual calibration data as well asother information used for predictive main-tenance e.g. overall time in operation, ma-ximum and minimum pH value, maximumand minimum temperature. A typical pHcontrol system including electrode, retrac-table assembly, intrisically safe Memosenscable and Mycom measuring electronics isshown in Fig.3.
Retractable assemblies are integral to flotationprocess safety and automate the sensor cleaning and calibration processes when linked to plant PLC or to Endress+Hauser automatic calibra-tion packages TOPCAL and TOPCLEAN.Fig.4 shows a typical pH control panel withintegral calibration buffer solutions and controlsfor automatic calibration and cleaning cycles.
