Adjustable flow limiters 242 are used when subsequent flow adjustment is required. These limiters are available in three versions, differing in dosing volume, visual flow indication, and number of outlets.
Type A — flow rates in the drip feed range from 0 to 0.01 l/min (0 to 0.02 pints). The 242 adjustable limiter is available with 1 to 14 outputs and a viewing window for flow monitoring. Type B offers a constant dosing volume from 0.01 to 1.0 l/min (0.02 to 2.11 pints) and is equipped with 2 to 12 outputs. Type C — dosing volume range from 0.01 to 2.0 l/min (0.02 to 4.23 pints). Depending on the distributor, versions with 2 to 6 outlets are available. Types B and C feature a spring-loaded metal pin in the inspection window for visual monitoring of oil flow.
