EZ Series® In-Site® CL with Bluetooth® Duplex Demand/TD

Get In-Site to Your On-Site™

Data Logging Panel with Wireless Bluetooth®

The EZ Series® In-Site® CL Duplex control panel is designed to control two (alternating) 120/208/240V single phase pumps in water and sewage installations. The alternating action equalizes pump wear. In addition to the alternating pump control, this system provides override control should either pump fail.

The EZ Series® In-Site® CL data logging control panel is now available with wireless Bluetooth® connection for your smartphone or tablet. Now there is no need to open the panel for configuration, viewing status or downloading data using the new EZ Connect™ Mobile App.

The panel configuration can be easily converted in the field to either a timed dose or demand dose using a tablet or smartphone. All system data including pump run times, pump cycles, alarm conditions, power outages, and more can be downloaded to the same mobile device using the exclusive EZ Connect Mobile App. 

The optional post models include an access door. The post can be mounted in the ground directly, over a 4x4, or conduit.

The C-Level™ sensor, is a pressure transducer that senses the liquid level in the tank and sends a signal to the EZ Series® In-Site® panel. C-Level™ CL40 sensor operating range is 3-39.9 inches (7.6-101.3 cm). C-Level™ CL100 operating range is 3-99.5 inches (7.6-252.7 cm).
