Greyline Instruments DLT 2.0 Differential Level Transmitter

Differential level and control plus open channel flow monitoring with two non-contacting ultrasonic sensors.
The Greyline Instruments DLT 2.0 differential level transmitter uses two non-contacting ultrasonic sensors to provide differential level and control as well as open channel flow monitoring. This versatility reduces costs and simplifies instrumentation and makes the DLT 2.0 a great solution for barscreen level control at wastewater treatment plants, pump stations and combined sewer systems.

The DLT 2.0 can measure both differential level plus flow through a flume. 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 totalize open channel flow.

The DLT 2.0 is easy to set up and operate. Simply use the built-in 5-button keypad/menu system to input the calibration parameters. 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.

Other DLT 2.0 applications include two-tank inventory where you can monitor level in two tanks with one instrument. The DLT 2.0 will alternate display of level in both tanks plus transmit 4-20mA outputs. Use the built-in relays to activate alarms or level controls. This versatile dual-sensor instrument can also be configured as a submergence alarm for Parshall flumes.
