Greyline SLT-5.0 | Ultrasonic Level & Open Channel Flow Monitor | 2 Relays, 4–20 mA
The Greyline SLT-5.0, sold by Micronics, is a non-contacting ultrasonic monitor that works either as a level controller for tanks, sumps and pump stations or as an open channel flow meter on flumes and weirs. In level mode it displays level or volume and drives pumps and alarms; in flow mode it displays, totalises and transmits flow, with common flumes and weirs selectable from the menu. The sensor mounts above the liquid, so there is no contact and no sensor maintenance.
Key features
- Level, range or open channel flow modes with built-in 5-key calibration menu
- Two programmable control relays for pump control, alternation and alarms
- Isolated 4–20 mA output (1000 ohm) with programmable offset
- False echo suppression and automatic temperature compensation
- Plug-in options: 4 extra relays and 2 million point data logger with Windows software
- Electrical surge protection; intrinsically safe sensor option
