Description

The Model 250 & 251 Digital Displays from McMillan Company allow you to use your flow sensor to its fullest potential.  Imagine being able to program a 16-point calibration curve into a unit (9 points on the 251), and have it display the corrected values, even retransmitting the linearized signal with the optional analog output card!   Imagine programming in alarm setpoints, with actual relay contacts, with hysterysis and startup options.  The easy to use, menu-driven interface makes programming a snap, and the bright LED display ensures clarity even under bright-light conditions.   The units even provide a 12.5VDC power source for connecting any McMillan Company flow sensor, saving you money on additional power supplies!  Power cable provided to power unit from wall outlet.
