M-2700 Integrated Ultrasonic Flow Meter
Brand: MalemaThe M-2700 series is an integrated flow meter in a small package.
The M-2700 utilizes the latest high-speed digital signal processing (DSP) technology to provide a cost effective flow measuring solution with no compromise in performance.
Malema DSP algorithms sample the entire wave form resulting in a demonstrable advantage in bubble immunity over traditional ultrasonic technologies.
The flow sensor is a U- or Z-shaped PFA tube with no internal obstructions, moving parts, or mechanical seals.
The M-2700 is compatible with high-temperature liquids and is an ideal choice for use where minimal footprint, high purity, corrosion resistance, low pressure drop, and easy installation are desired.
