a.<\/strong><\/span> Hot Wire Anemometer<\/strong><\/span>
\n This method is quite simple: by using a wire heated by electric current, the current flowing in the wire is made to remain constant using a constant current source.<\/span> If no air flow, the wire will cool (as we blow out the candles) by the cooling of the wire, the wire resistance decreases.<\/span> Because of the constant current source is used, then we can not censor the voltage at the ends of the wire.<\/span> Sensors of this type have a very good sensitivity to censor a slow gas flow.<\/span> But unfortunately, the whole sensor installation is quite difficult.<\/span>
\n\"image\"<\/a>
\n Here applies the formula:<\/span>
\n where: I = current wire<\/span>
\n Rw = wire resistance<\/span>
\n Kc = conversion factor, heat to electric power<\/span>
\n Tw = temperature wire<\/span>
\n Tt = temperature of flowing fluid<\/span>
\n Hc = coefficient of the film (coating) of heat transfer<\/span>
\n A = heat transfer area<\/span><\/p>\n

b.<\/strong><\/span> Heat propagation<\/strong><\/span>
\n<\/strong> In the heat propagation techniques, the heater mounted on the outside of the pipe, the pipe is made of metal.<\/span> On the left and right heating, fitted thermal insulation materials, and in this insulator mounted temperature sensors.<\/span> When udaramengalir from left to right, then the left side temperature will be colder than the temperature right.<\/span>

The temperature sensor used may be a resistive sensor but commonly installed are thermocouple because it has a fast temperature response.<\/span> Heat propagation flow sensor type long, heat the whole part of the air duct, requiring heating to tens of kilowatts, to reduce the thermal power used a new type with a small portion deflect air into the sensor.<\/span><\/p>\n

c.<\/strong><\/span> Flowmeter Radio Active<\/strong><\/span>
\n<\/strong> Flow measurement techniques with active radio is by firing neutrons particles of an active radio transmitter.<\/span> At a certain distance towards the outlet, mounted detector.<\/span> If there is a stream, then it will be detected radioactive particles, the number of particles detected at certain intervals will be proportional to the velocity of fluid flow.<\/span> Another technique that still uses active radio technique is by mixing radioactive substance into the fluid then in certain parts installed detector.<\/span><\/p>\n

This technique is done if there is difficulty to measure, for example because the flow of materials consists of substances which are at various phases.<\/span> Active radio engineering biaa also used in the treatment of seeking the position of blood vessels that bad for people with paralysis.<\/span>
