The M-2800 ultrasonic flow meter consists of an inline flow sensor and electronics in one package. The flow sensor is a straight-through PFA tube with a pair of assemblies of angled wedges and piezoelectric crystals mounted on it. The M-2800 utilizes the latest digital signal processing (DSP) technology and provides flow measuring solutions with minimum compromise in performance. The compact integrated package includes sensor and electronics, and saves space and minimizes cabling, facilitating an easier installation.

Features:

  •  Sensor and electronics in one package
  • No dead legs, no obstructions
  • Straight flow path
  • No moving parts in the flow path
  • Straight flow path
  • Minimal pressure loss
  • Accuracy ± 1% F.S.
  • Repeatability ± 1% F.S.
  • All wetted parts made of PFA
  • Free from ion or practice contamination
  • Corrosion resistant
  • Wide rangeability
  • Easy installation with compact meter body                                                              

 

There are no moving parts or mechanical seals. The M-2800 is an ideal choice for use in the semiconductor industry where minimal footprint, high purity and corrosion resistant wetted parts are required.
