IMP+

The IMP+ non-contacting ultrasonic sensor is designed to be used wherever you need an accurate and reliable level measurement. Its digital echo processing means the IMP+ is perfect for slurries, liquids, or anywhere you need a display telling you the level or analog output to interface with your site control system or drive a display.
There are several measurement ranges available from 200 mm to 10 m (7.9 in to 32.8 ft) and each can be wired for 2 or 3-wire operation. All options feature an LCD display and digital temperature measurement and compensation. When combined with Pulsar’s PC Suite, users are able to download, analyze and store echo profiles, set up the IMP’s parameters, install the new firmware to your IMP, and add a flow curve to be able to configure level to flow linearization.
