The new Greyline DLT 2.0 can measure both differential level at a bar screen, plus open-channel flow through a flume. It works with two noncontacting ultrasonic sensors. It includes relays for bar screen rake and level control as well as three 4-20mA outputs (upstream level, differential level, downstream level or flow). The large backlit LCD display shows level, differential level, flow and total flow. Intrinsically safe sensors and data logger are optional.
