Overview
The DLT 2.0 is a simple solution for barscreen level control at wastewater treatment plants, pump stations and combined sewer systems. It includes two non-contacting ultrasonic sensors to measure level. With sensors positioned above a channel, up and downstream from the barscreen, the DLT 2.0 can display and transmit differential level. The downstream sensor can also be installed above a flume or weir to measure and totalise open channel flow.
Other applications include two-tank inventory where level in two tanks can be monitored with one instrument. The display will alternate between the level in both tanks plus transmit 4-20mA outputs. Built-in relays can be used to activate alarms or level controls. This versatile dual-sensor instrument can also be configured as a submergence alarm for Parshall flumes.
