  • Panel Meters
    , A/B, etc). Relay outputs: Up to 6 setpoint relays for control & alarms. Digital communication: RS232, RS485 or Ethernet for software setup & networking. Special types & options: dual input, loop powered, triple display, power meters, sealed front. Digital Bargraph Meter - Digital Display & Analog Bar
  • TC7136/TC9400 Digital Readout Frequency Meter
    Two low-cost integrated circuits can be combined to create a simple digital frequency meter. The combination of a frequency-to-voltage converter (FVC) and a dual-slope, analog-to-digital display converter (ADC) makes a small 2-chip frequency meter that can be run from one 9-volt battery

    and load current and maintain Class 1 accuracy. The firmware discussed measures and displays rms voltage and current, as well as kWh, presented in a clear digital format on an LCD. AN939, Designing Energy Meters with the PIC16F873A AN939. Designing Energy Meters with the PIC16F873A
  • Modern Electronics Meet Turbine Meters
    Meters and Modern Electronics. As inherently digital devices, turbine meters can easily be paired with powerful microprocessors to offer a host of cost/performance advantages over other flow meter designs. These electronic packages are similar to those used and accepted in magnetic, differential
  • Turbine Flow Meters Will Never Be The Same
    techniques, enabling them to output "real-time" corrected K-factor flow data in as little as 7.5 ms with an accuracy of ±0.1% of reading over the repeatable range of the flow meter. Turndown ratios to 100:1 are possible with enhanced digital resolution in the low flow range of the turbine meter, where
  • Introduction to Flow Meters
    and of the overall installation. The first step in flow sensor selection is to determine if the flowrate information should be continuous or totalized, and whether this information is needed locally or remotely. If remotely, should the transmission be analog, digital, or shared? And, if shared, what
  • Combining the Best of Analog and Digital Indication
    of relative signal level. When a process condition became critical, a DPM was then used for more exact readings. The Digital Bargraph Meter was developed to combine the best features of analog and digitial indication. This article reviews the development of bargraph meters and their use today in a variety
  • CMOS Digital Isolators Provide Data Protection for Smart Meters
    to the controller. CMOS digital isolators provide accurate, uncorrupted power measurement data across an isolation barrier to address these concerns in smart meter applications.
