The WebMaster has proven to be the most revolutionary product the Water Treatment market has ever seen. Walchem's Patent-Pending ShoulderTap Server-On-Demand technology provides instant real-time access to the WebMaster controller when you need it without the need to be permanently connected to the Internet. It offers the ability to control and monitor cooling tower and boiler systems using a standard web browser from any computer - anywhere in the world.
Unlike traditional modem-to-modem communications, ShoulderTap eliminates long distance phone calls, proprietary software and allows simultaneous multi-user access. In addition, the WebMaster delivers a range of new technology capabilities including user-friendly programming, multi-user access and e-mail notifications for datalogs, alarms and system summaries.
Now the WebMaster-GI brings the same capability to any pH, ORP or Conductivity application. WebMaster-GI offers the flexibility of SCR Mapping (Sensor-Control-Relay), which allows you to select the Sensor (pH, ORP, conductivity or any analytical analog input), the Control method (ON/OFF, Time Proportional, Flow Based or Timer) and assign them to any Relay. With up to 21 user-defined inputs, the WebMaster-GI can be programmed to control and monitor an array of different input combinations. Each sensor input (either direct sensor or 4-20mA input) can be assigned to a powered relay for control. WebMaster-GI has the ability to bring in 8 analog inputs, 9 digital inputs and is equipped with 8 powered relay outputs. Sensor inputs can also be assigned to any one of the four 4-20mA outputs.
WebMaster-GI is ideal in the following applications –
