(1) The declination variometer enables us to measure variations in the declination of the Earth magnetic field.(2) An instrument known as a variometer helps to show the pilot when the glider is in a thermal, and the pilot circles within it and gains altitude.(3) There are several other kinds of lift, but a paragliding variometer is mostly used for thermal lift.(4) Gaston, our pilot, checks two gauges - the variometer measures the balloon's rate of ascent or descent.(5) The litz cable, used throughout the NSS antenna system and in the variometers is made in Germany and consists of over 100,000 insulated copper strands surrounding a hemp core.(6) CEC makes motor packages for the variometers to provide fine positioning control and position readback.(7) Most variometers indicate vertical speed by measuring the flow of air into and out of the container, called a reference chamber.(8) Pressure transducers replaced flow sensors in our variometers in 1982 and their reliability and accuracy has been excellent.
