Max Machinery 272-5X8 BIDIRECTIONAL TRANSMITTER (210_240 SERIES FLOW METERS) - Manual (Page 10)

Table I list the approximate volumetric displacements of flow meters that can be used with the 272
transmitters. Use this table to calculate the RPM of the flowmeter at maximum flow.

FOR EXAMPLE: THE MODEL 213 MAXIMUM RPM IS: 1800 CC/MIN ÷ 0.870 CC/REV = 2069 RPM.
Table II list the RPM range of each Range Switch setting for all three 272 transmitters. Use this
table to estimate the correct range position.
