1.0 Introduction

The Micro-Flo flowmeter is designed to display flow rate and flow total on
a six digit LCD display. The meter can measure bi-directional flows in
either vertical or horizontal mounting orientation. Six flow ranges and four
optional pipe and tubing connections are available. Pre-programmed
calibration K-factors can be selected for the corresponding flow range or a
custom field calibration can be performed for higher accuracy at a specific
flow rate. The meter is factory programmed for the correct K-factor of

the body size included with the meter.
