Meter Conversion Kits

Smith-Blair Meter Conversion Kits make changing from a large diaphragm meter to any type of meter that accepts flange connections easy. With the kit, a new meter can be connected using the same footprint as the large diaphragm meter without removing all of the set's piping. If there is an existing bypass, it can be maintained while changing out the meter, avoiding costly customer relights.

Meter Conversion Kit - For handling a range of end-to-end dimensions, allowing greater field flexibility without additional fittings
