Datasheet
Technical features
| Two sensors above the channel, up- and downstream of the barscreen, give differential level for screen-cleaning control | |
| Downstream sensor can sit over a flume or weir to measure and totalize open channel flow | |
| Temperature probe inside each sensor compensates for changing air temperature | |
| Backlit matrix display of both levels, differential, flow, totalizer and relay states | |
| 5-key calibrator with English, French or Spanish menus | |
| Relays programmable for level control, differential control or flow-proportional pulse |
Applications
| Barscreen control at wastewater treatment plants and pump stations | |
| Combined sewer systems; differential level across filters and screens | |
| Open channel flow over flumes and weirs |

Description
The Greyline DLT 2.0 is a differential level transmitter that uses two non-contacting ultrasonic sensors to measure level upstream and downstream of a barscreen and transmit the difference, typically to start screen cleaning. The downstream sensor can also be mounted over a flume or weir to measure and totalize open channel flow.
It reads to ±0.25% of range or 2 mm over a 4.6 m range (9.7 m optional), has three isolated 4–20 mA outputs and two programmable 5 A relays, and is housed in a NEMA 4X polycarbonate enclosure powered from 100–240 V AC or 9–32 V DC.
Argonmark Ltd supplies Greyline instruments across Bangladesh — Dhaka, Chattogram, Gazipur, Narayanganj and the gas fields, refineries, terminals and power plants beyond. Send us the model, range, process connection, output and any hazardous-area requirement, and we will confirm the right configuration, lead time and price.
