Introduction

The eFlo-H 2.0 (high pressure gas) and eFlo-L 2.0 (high pressure liquid) (from hereon referred to as eFlo or eFlo 2.0) instruments are Super Systems Inc.’s electronic flow meters for higher pressure applications. eFlo works by measuring the differential pressure (the difference in pressure at two points) of a gas or liquid flowing through a specially designed opening in the flow assembly. Based on properties of the flowed gas or liquid (a.k.a. media), the differential pressure can then be used to calculate the flow rate of the media.

 

The eFlo 2.0 uses a mathematical curve to calculate the flow of a gas and features built-in diagnostic information, flow rate, pressure alarms, and a flow rate totalizer.  The automatic meter can be set to automatic or manual valve control mode. Automatic valve control mode allows the eFlo to use a flow rate or valve position setpoint as a basis for adjusting the valve (and thus the gas flow) using a built-in valve motor. The setpoint can be programmed manually by the user or obtained by the instrument from a 4-20 mA analog signal or a digital signal over RS485.  Manual valve control mode allows the user to manually set the valve position through the interface.

 

eFlo 2.0 is built for use in harsh industrial environments.

 

This manual also covers configuration and control using the eFlo web interface.
