In general you can expect a turbine meter to keep counting below its minimum range, but it will lose some of its accuracy. Normally it will completely stop at ½ of its published minimum flow. For example a ½ in. meter that reads between 1 and 10 GPM will be able to stretch down to around ½ of a gallon per minute. Keep in mind that nothing below the published minimum flow is guaranteed, and not all turbines will give this much extra performance.
