* Due to operating conditions and instrumental errors, there may be differences between the values indicated (L/MIN)
in the table above and those that are actually used by the customer.
* The values shown in the table above are data for Model 2412L for illustrative purposes only. As compared with the 2412L, flows on the 2412T will
run less smooth when the flow rate increases. It is therefore recommended that the 2412L be used for flows of 5 L/MIN or more.
