The MEMFlo Flow Transmitter (MFT) is a state-of-the-art, microprocessor based two-wire transmitter with 4-20mA/ 0-5Vdc output, digital flow rate and total flow display. It combines our time-proven variable area technology with a high tech processor and solid state circuitry.

The MEMFlo Flow Transmitter (MFT) is sealed against industrial contamination by a NEMA 4, 12,13 (IP 57/52/54) rated enclosure and is available for either liquid, gas or steam service. The MFT is capable of calculating and displaying both flow rate and total accumulated flow. The flow rate and total flow can be displayed in any of the user selectable measurement units. The monitor's large 8 digit numeric LCD makes extended range viewing practical. The second 8 character alphanumeric display provides for selectable units viewing in RUN mode and prompts for variables in PROGRAM mode.

All MFT's come pre-calibrated from the factory. However, the unit may be adjusted by the user to meet specific system requirements. Calibration parameters are included for:

• Specific gravity compensation (all fluids)
• Viscosity compensation (petroleum-based fluids)
• Pressure and temperature compensation (pneumatic applications)

All meters include an analog output that can be configured for 0-5 Vdc, 0-10 Vdc, or 4-20 mA current loop.
