MEMFlo MFAM Process VA Flow Meter
MEMFlo MFAM All Metal Flow Meters are simple, accurate, meters for use in a wide range of industrial liquid and gas applications. These meters have an excellent tolerance to suspended solids and measure flow to one percent accuracy. With an all metal design, these meters are ideal for high pressures, high temperatures, steam, dirty fluids, and harsh service environments. MFAM All Metal Flow Meters use an internal magnet to carry an external indicator in a non-wetted enclosure. And they can be supplied with the MFT2 2-Wire Transmitters for flow rate and total. Additionally, these meters can be supplied with a high temperature indicator option for service up to 600°F.

Principle of Operation
MEMFlo MFAM All Metal Flow Meters are patented variable area flow meters using the the volumetric principle of flow measurement. These VA Flowmeters consist of five main parts including the body/measuring tube, core tube, float assembly, scale, and pitot tube. The meter is not a glass tapered tube, rather the media enters the meter vertically at the bottom inlet port and flows upward into the core tube. Then the media flows horizontally through the core tube slot and exits the meter through the side outlet port. During this process the media lifts the float assembly in the core tube in direct proportion to the rate of flow. The slotted core tube design gives the meter an excellent tolerance to suspended solids and there are no springs, cams, or dynamic seals to wear out.
The external indicator displays flow rate. The MFT2™ Flow Transmitter has an analog 4-20mA or 0-5, 0-10 VDC output to a remote display, PLC, Recorder, or other customer-supplied receiver.
Using a simple and rugged design, the MEMFlo All Metal Flow Meters measure to 1% accuracy.
