TsIKLON, a novel partial thermal flowmeter

The novel flowmeter considered operates on the principle of determining the heat exchange between a gas or liquid flow and the surface of a thermal probe inserted into the flow. Energy consumption is reduced considerably by implementing partiality by means of a flow divider (transducer);at the same time the range of applicability is broadened substantially. The design of the sensor (including the divider) is described, the reduction coefficient and the heat-exchange coefficient are calculated, and a formula is given for the relation between the massflow and the thermal power “removed” from the sensor+thermal probe by the flow.
