Overview

About the WMDO1001-FM DO Meter.

The WMDO1001-FM is an industrial online dissolved oxygen (DO) meter for continuous monitoring of oxygen content in boiler feed water, condensate water and sewage. This microprocessor-based field meter works with a polarographic electrode and switches automatically between ppb and ppm ranges, from 0 … 100.0 µg/l up to 0 … 20.00 mg/l, so one instrument covers both trace oxygen in power plant water and higher levels in wastewater. An English-language LCD with a menu structure similar to a computer lets operators work from on-screen prompts without needing the manual.

Features

  • Automatic range switching from µg/l (ppb) to mg/l (ppm)
  • Works with a polarographic DO electrode
  • High-resolution LCD with all data, status and prompts in English
  • Classified menu structure with text-based operation
  • Multi-parameter display: oxygen concentration, input or output current, temperature, time and status at once
  • Large 10 × 10 mm main digits readable from a distance, plus six sub-displays
  • 0–10 mA or 4–20 mA current output, RS485 communication and alarm relay
  • Data storage for 1 month at 1 point per 5 minutes; data retained for 10 years on power failure
  • IP54 aluminium shell for panel mounting

Applications

  • Boiler feed water and condensate
  • Thermal power plants
  • Power plant demineralised water
  • Trace oxygen measurement points
  • Sewage treatment
