GOLD Series G101 & G102 Flo-Sensors


Do you have an application where every percent counts?  Then look no further than the McMillan Company GOLD Series Flo-Sensors.  These sensors offer 0.5% full scale accuracy/linearity combined with 0.2% full scale repeatability to ensure that you get the precise measurement you need, each and every time.  And when the G101 or G102 Flo-Sensors are combined with the new McMillan Company Model 250 Multi-Function display, virtually all accuracy errors may be eliminated (using the 16-point linearization feature).  The G101 and G102 feature an integrated 6 foot cable with pigtail leads.

For even more versatility, the G101 or G102 Flo-Sensors may be conformally coated (see E Option below).  This coating makes the Flo-Sensor submersible and splashproof (IEC IP67 rated).  The G101 Flo-Sensor is all plastic and comes standard with plastic compression fittings, whereas the rugged G102 Flo-Sensor is made from brass and comes standard with brass compression fittings.
