The KOBOLD DOG-4 flowmeter is used for flow measurement of gases. The gaseous media flows through an orifice within a tube. Bypass bores are located at the sides. The dynamic pressure at the orifice causes a small part of the volumetric gas flow to divide into the bypass channel. The division ratio remains constant over the whole measuring range. The bypass channel contains the oscillator – the measuring cell itself. When the gas flows through the measuring cell, a gas column oscillates in a U-shaped channel mounted to the left and right. This oscillation frequency is proportional to the flow velocity and thus to the total volume flow. The oscillation frequency is sensed with a platinum sensor. An alternating electrical signal is generated and is displayed and/or transmitted by the electronics module.
