Q548. For AGR vents, Option 3, the MRR says a meter must be installed, but then says in the next sentence that engineering calculations may be used if a meter is not installed - this is unclear on whether or not a meter is required
A548. The rule requires the use of a meter if one is in place. If a continuous flow meter is not already in place, then reporters have the choice of installing a continuous flow meter or alternatively using an engineering calculation to estimate the flow rate; please see §98.233(d)(5).
