WBL/WCM
|
|
|
|
The WBL400 Boiler Controllers and WCM400 Condensate Monitors represent the latest in technological and innovative advancements from Walchem.
All of the standard features you’d expect in conventional boiler controllers/condensate monitors are included, plus optional simple-to-use information management tools that enable water treatment professionals to deliver more effective service to their customers.

|
|
| |
The WBL/WCM400 controllers have the ability to store conductivity and temperature values, water usage, relay status, and user settings. A USB memory stick is all that’s needed to extract the information.
Download logs from the USB stick to a PC at your convenience, or copy your preferred treatment program settings to another controller to speed start-up.

Four chemical feed options
• Feed & blowdown simultaneously, with or without feed lockout timer
• Feed after blowdown has finished, as a percentage of blowdown time
• Feed as a percentage of time elapsed
• Feed as a percentage of make-up water
|
Choice of measurement units
• To customize your control or complement your calibration procedures, conductivity may be displayed as μS or PPM; temperature as
°F or °C.
|
Choices of blowdown modes for timed samples
• In intermittent sampling, the blowdown valve is open until the set point conductivity is reached.
• In intermittent with timed blowdown, the blowdown valve opens for a set programmable time.
• In intermittent with time proportional blowdown, the blowdown valve opens for a variable time that is calculated based on the conductivity of the sample versus the set point
|
| Self-diagnostics
• Software, electronics and sensor are constantly monitored, without having to take the controllers off-line.
|
Detects flashing during timed samples
• Rechecks the conductivity after the sample valve closes and reopens if the reading is now above set point.
|
Automatic temperature compensation
• Conductivity measurements are temperature compensated to ensure the higest accuracy.
|
| |
USB Flashstick Support
• Optional for data logs, event/relay and reset logs, and user configuration file import/export
