Bargraph Power Meters   

Bargraph Power Meters – Weschler Instruments    

Watt Meters – Weschler Instruments

     •  Use on Single & 3 Phase Systems

     •  Two Switchboard Sizes: 4½ & 8¾"


     •  Two Types:  Hall Effect & Electronic Sensing


     •  Auxiliary Power to 264 VAC / 250 VDC


     •  Rugged Metal Case fits Standard ANSI Cutout

These Weschler BG Series Bargraph Meters are optimized for AC power measurements.  Bargraph meters combine the visual indication of an analog meter with the precision of a digital instrument. The ACP4 models utilize self-contained current transformers (CT) and accurate solid state circuitry to measure both single and poly phase systems.  The ACP3 models combine internal current transformers, potential transformers and hall effect sensing for accurate measurements. 

Both models are housed in a rugged steel case for long life in utility switchboards and other monitoring applications.
