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
