IMP+ Self-contained, ultrasonic level measurement without compromise. The IMP series is a range of compact, low-profile, self-contained units with the benefit of digital echo processing. There is an IMP unit to suit your application. 3 m (9.8 ft), 6 m (19.7 ft), and 10 m (32.8 ft) range versions are available and each can be wired for 2 wire or 3 wire operation. The IMP+ features an LCD display and digital temperature measurement and compensation with 2 relay outputs as standard. The IMP+ can be used wherever you need a reliable, non-contacting level measurement, and digital echo processing means IMP+ is perfect for solids or liquidsit can be installed in sumps, tanks, silos, or anywhere you need a display telling you the level, or analog output to interface with your site control system or drive a display. Battery Power When used on battery power for intermittent (wake-up) applications, the IMP+ features a high-speed boot up of around circa 3 seconds which maximizes battery life. For example, if an IMP were switched on every 15 minutes for a 3-second reading, the average current is a mere 40μA. System Integration Active and passive (sourcing and sinking) analog outputs assist with system integration, especially when retrofitting into older installations. THE RIGHT METER FOR • Tank Level Applications • Chemical Dosing • Simple Level Indication • Open & Closed Vessel Level Requirements • Solids Level Indication Simple to Install The compact IMP+ is only 175 mm (6 in) high with a 130 mm (5.1 in) diameter. Cable glands are provided and IMP+ can be simply screwed into a 1.5” or 2” universal fitting (a 1.5” or 2” adapter is available). High transducer power and tight beam angles, together with Pulsar Measurement’s digital echo processing, makes IMP+ ideal for many “difficult” applications such as dusty or foamy environments, or where a tank has unavoidable intrusions.

The integral display makes programming IMP+ extremely straightforward. IMP+ can be completely set up, without compromising the IP rating, using the integral keypad alone with no need for a PC. Optional IMP PC software makes it easy to fine-tune IMP’s performance and “clone” any number of IMP units to the same settings if, for example, they are being used on a tank farm. IMP PC is optional software that extends the capabilities of the IMP+ and allows a user to: • Download, analyze, and store echo profiles. A great way to see exactly what is happening in the application. Fine-tuning for...
