Differential level and control plus open channel flow monitoring with two noncontacting, ultrasonic sensors. Differential Level Transmitter with Non-Contacting Sensors One Instrument Does the Work of Three The DLT 2.0 is a simple solution for bar screen level control at wastewater treatment plant headworks, pump stations, and combined sewer systems. It includes two noncontacting ultrasonic sensors to measure level. Sensors are positioned above a channel, up and downstream from the bar screen, 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 totalize open channel flow. Three 4-20mA outputs are configured to transmit upstream level, downstream level (or flow), and differential level. Built-in relays can be calibrated for level control, differential level control, or open channel flow. THE RIGHT METER FOR • Bar screen Level • Pump Stations • Combined Sewer Systems • Level Control • Differential Level Control • Open Channel Flow One sensor can be installed on each side of a bar screen to continuously monitor, transmit, and control level. The built-in control relays or 4-20mA outputs can be used to automatically activate the bar screen rake at preset levels.

Multi-function Level Transmitter Bar Screen Differential Plus Open Channel Flow Reduce costs and simplify instrumentation at treatment plant headworks. With a bar screen upstream from a flume, the Greyline DLT 2.0 can measure both differential level and flow through the flume with just two ultrasonic sensors and one electronics enclosure. 4-20mA Open Channel Flow The Greyline DLT 2.0 includes three 4-20mA outputs and displays flow rate and total flow through the flume, plus upstream level and differential level. Monitor, transmit, and control bar screen level with one instrument. Mount the ultrasonic...
