MEMFlo™ MFVC PVC & CPVC flow meters are simple, accurate variable area meters and resistant to many acids, alkalis, salt solutions, and other corrosives. These meters have excellent tolerance to suspended solids and measure flow to one percent accuracy. Unlike tapered tube rotameters, the MEMFlo MFVC flow meters have an indicator disk near the edge of the sight tube for visibility even in many dirty fluids. Alternatively, the magnetic indication is available for accurate reading regardless of the media. These meters can be supplied with the MFT2™ 2-Wire Transmitters for flow rate and total.

MEMFlo™ MFVC PVC & CPVC flow meters are patented variable area flowmeters using the volumetric principle of flow measurement. These MEMFlo™ meters consist of five main parts including the body/sight 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.
When using a polysulfone measuring tube, the flow rate is visible by reading the sight disc on top of the float assembly. When using the CPVC measuring tube, the flow rate is visible by reading the magnetic indicator, which corresponds with the float assembly. The optional MFT2™ Flow Transmitter has an analog 4-20mA or 0-5, 0-10 VDC output to a remote display, PLC, Recorder, or another customer-supplied receiver. Using a simple and rugged design, the MEMFlo PVC and CPVC flow meters measure to 1% accuracy.
