Greyline - Model DLT 2.0 -Differential Level Transmitter
The Greyline DLT 2.0 Differential Level Transmitter is a simple solution for differential level measurement including applications found in wastewater treatment plants, pump stations, and combined sewer systems. The Differential Level Transmitter includes two differential level sensors. Position each sensor at your desired location, above a channel, up and downstream from a bar screen for example, and the DLT 2.0 can display and transmit differential level measurement. The downstream sensor could even be positioned above a flume or weir to measure and totalize open channel flow.
Other applications for the DLT 2.0 include two-tank inventory, where you can monitor levels within two tanks with just one instrument, aiding stock control and process efficiency. The Differential Level Transmitter will alternate a display of level in both tanks, plus it will transmit 4-20mA outputs.
