MEMFlo MFVC PVC & CPVC Corrosive Resistant Process VA Flow Meter
The 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 an 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 in close proximity to the edge of the sight tube for visibility even in many dirty fluids. Alternatively, magnetic indication is available for accurate reading regardless of media. These meters can be supplied with the MFT2 2-Wire Transmitters for flow rate and total.

Principle of Operation
MEMFlo MFVC PVC & CPVC flow meters are patented variable area flow meters using the 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.
- Heavy bodied meters for corrosives and high purity fluids.
- Ideal for acids & caustics, deionized water, plating solutions, water treatment & corrosive gases.
- All plastic wetted components for maximum corrosion resistance.
- Extended flow ranges averaging 30 to 1.
- Disassembles in less than a minute without removing the meter from the pipeline
Repeatability: ± 1/2% of indicated flow rate
Rangeability: 30 to 1 average
Accuracy: ± 1% of 100% flow rate
Pressure Rating: Up to 150 psig for flanged models, or 300 psig, depending on meter type, temperature and service conditions.
