２-wire Ultrasonic Water level gauge – IMP Lite
IMP Lite can be used wherever you need reliable non-contacting ultrasonic level measurement and digital echo processing means IMP Lite is perfect for slurries or liquids and anywhere you need a display telling you the level, or an analogue output to interface with your site control system or drive a display.
The full IMP range is available with the wetted parts in PVDF build alternative for corrosive or aggressive applications.
Description
- Lower-cost alternative to IMP+ for level measurement
- Compact and low-profile
- 4 digit LCD display
