  • 1. Technical InformationProline Prosonic Flow B 200Ultrasonic flow measuring systemThe device for accurate, reliable biogas measurement undervariable process conditionsApplicationYour benefits Reliable measurement of wet biogas, digester gas and Biogas measurement for a wide range of applicationslandfill gas under low process pressure, low flowwith optional real-time measurement of the biogasrates and varying gas compositions.methane fraction combined with genuine loop-powered The Ultrasonic measuring principle is unaffected bytechnology.the gas composition. Sizing - correct product selectionDevice properties: Applicator - the reliable, easy-to-use tool for selecting Medium temperature: 0 to 80 C (32 to 176 F)and sizing measuring devices for every application Process pressure: max. 10 bar (145 psi) Installation - simple and efficient Nominal diameter: DN 50 to 200 (2 to 8") Short inlet and outlet runs Accuracy: Reduced wiring thanks to loop-powered technology Volume flow: 1.5 % o.r. Methane: 2 % abs. (optional)Commissioning - reliable and intuitive Loop powered transmitter made of aluminum or Guided parameterization ("Make-it-run" Wizards)stainless steelOperation - increased measurement availability Graphical local display with operation from the Multivariable measurement: volume flow and,outside (Touch Control)optionally, methane fraction and temperature Communication via 4-20 mA HART No pressure loss Ex approvals accepted worldwide: ATEX, IECEx, Diagnostic capabilityCCSAUS, NEPSI (intrinsically safe or explosion proof Automatic data restore by HistoROMdesign) Cost-effective Life Cycle Management by [email protected]/06/EN/02.1271196568
