The KOBOLD flow meters DOG-4/-6 are used for flow measurement of gases. The DOG-6 comes with a special sensor construction and an inclined measuring head. This inclination optimises the condensate drain specifically for applications involving wet gases, e.g. biogas. The medium flows through an orifice in a tube. Bypass bores are located at the sides. The dynamic pressure at the orifice causes part of the gas volumetric flow to flow into the bypass. The division ratio remains constant over the whole measuring range.

Oscillation Flow Meter Model DOG-4 / -6 Pressure Loss/Flow The diagram applies for gases with a density of air at NPT (0°C and 1013.25 mbar). The pressure loss is always proportional to the density of the gas. For example, the pressure loss doubles at 100% higher operating pressure. Pressure drop [mbar] Calculating the Actual Density The actual density can be calculated with the following formula: density at 1 bar abs. and 0 °C (= 273 K) temperature in K (= °C + 273 for example 20 °C = 273 + 20 = 293 K) 273 K operating pressure in bar (absolute pressure) Calculating the Norm Flow QN = Q ∙ No...
