SMART TDS BLOWDOWN CONTROLLER
2.2 Typical applications - BCS 920 Automatic TDS Blowdown Systems
Smart Automatic TDS Blowdown Controller BC 900, detects the electrical conductivity (TDS - Total Dissolved Solids)
of boiler water via the Conductivity Probe CP 920.
The TDS Blowdown Control Valve BCV 915 opens and closes in response to a high TDS signal from Smart Automatic
TDS Blowdown Controller BC 900. Keeps open until conductivity of the boiler water drops.
If the conductivty is lower than the set point the TDS Blowdown Control Valve BCV 915 remains closed.
Please refer to "BCV 900 Installation and Operation Manual for Automatic TDS Blowdown Control Valve" and
"CP 920 Installation and Operation Manual for Conductivity Probe" for detailed information before assembly.
