M-2700 Integrated Ultrasonic Flow Meter

Industry: Semiconductor
Call for pricing
The M-2700 series is an integrated flow meter in a small package. Transit-time ultrasonic technology with the latest digital signal processing (DSP) determines flow rate to ±1% of reading.

The 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.

The M-2700 utilizes transit-time ultrasonic technology to determine flow rate. Two piezoelectric transducers mounted at the ends of the measuring tube alternately transmit and receive ultrasound energy pulses. The difference between upstream and downstream transit time of the pulses is proportional to the velocity of the fluid, and is used to calculate flow rate.
