WebSep 26, 2000 · Hi all, I would like to know if somebody has any experience with the use of hot wire ammeter to measure the airflow of a combustion airfan. The expected flow speed is 20 to 40 meter/sec. Any comment, like brand name problems solutions etc., are welcome. Thanks in advance Ronny WebThe ammeter is used to measure the electric current in the electric circuit, measured by Ampere (A). The ammeter is designed using a moving coil with a pointer moved by a galvanometer. Don’t mistake it with a voltmeter when connecting it with an electric circuit.
WebA type of ammeter in which an electrodynamic magnet (one sensitive to the flow of electrical current) responds to alternating and direct sources. Hot Wire Ammeters These use a thermally sensitive wire which expands when it gets hot to display amp levels in a particular circuit. Milliammeters and Microammeters WebHot wires ammeters uses the heating effect of current so it is all the same for both a.c. & d.c. as heat generated is square function of current so even the sign in a.c. doesn't matter.
