The Checkline LMC Yarn Length Meter, Measures Centimeters is a precision instrument that accurately measures the amount of yarn being fed from a textile machine feeder to a take-up device during one or more cycles or rotations of the machine cylinder. LMI / LMC Yarn Consumption Meter units are ideal for comparing yarn consumption from feed to feed and machine to machine on circular and flat bed knitting machines, and for other textile processes where yarn length is to be accurately measured.
