Product Description
SSI Super Systems EF170178 TRIM eFlo Electronic Gas Flow Meter, Second Generation
PN: EF170178
The eFlo instrument is Super Systems Inc.’s 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.
The eFlo features built-in high and low flow rate alarms and a flow rate totalizer. The gas flow valve can be operated in manual mode or automatic mode. Automatic mode allows the eFlo to use a flow rate 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 4-20mA analog signal or a digital signal over RS485.
The eFlo unit uses a male 9-pin D-Sub connector for electrical connections, and is included.
