Introduction

 

The eFlo 2.0 instrument is Super Systems Inc.’s latest electronic flow meter. eFlo works by measuring the differential pressure (the difference in pressure of a gas at two points) of a gas flowing through a specially designed opening in the gas flow assembly. Based on properties of the flowed gas, the differential pressure can then be used to calculate the flow rate of the gas.

 

eFlo 2.0 uses a mathematical curve to calculate the flow of a gas and features built-in diagnostic information, flow rate and 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.
