1 MEDIDOR DE VAZÃO TIPO ENGRENAGENS PARA LIQUIDOS VISCOSOS Measuring range:.- to 1-5 L/min Measuring accuracy: ±.3 up to ±1 % of actual flow pmax: bar tmax: 15 C Process connection: G 1, G 3, G 1, G 1 female thread Material: Cast iron or stainless steel SERIE DZR COM ENGRENAGENS CILINDRICAS

2 Desription The KOBOLD Gear Wheel Flow Meter series DZR have been designed for a cost effective flow measurement for viscous fluids. The measuring unit consists of a pair of gear wheels which is moved by the flow according to the principle of gear wheel motor. The bearings are according to the material combination either ball bearings or gliding bearings. The different versions vary through different housing materials, lubrication properties, through the medium being used and the accuracy. Version DZR-1 Flow measurement, Hydraulic test rigs for: Oil, Brake fluid, Diesel, Skydrol lubricating, low viscous DZR- Oil batching, Batching installations Gear Box Oil, lubricating, mid viscous DZR-3 Consumption measurement Printing machines, Offset colour, lubricating, high viscous DZR- Ratio control, -Component plant, Polyol, Isocyanate, Glue, Resin, Silicone, low lubricating, mid viscous DZR-5 Batch control, painting plant, clear paint, Clearance volume sealing, low lubricating, mid viscous DZR- Flow measurement, painting plant, Solvent, lubricating, mid viscous Technical data Accuracy: Repeatability: Max.
