The Microflex LR MI transmitter with display and Microflex LR MS smart instrument are available with four acoustic frequencies to reliably track levels under extreme conditions. They have ATEX certification for hazardous areas and can operate from 9-24VDC with optional relays and low power modes. The Ranger 1000 and 3000 ultrasonic level transmitters have integral displays, IP67 ratings, and simple programming for measuring liquids and solids within specified ranges and resolutions.

9. The high quality and compact construction of
the ranger 1000 and 3000 ultrasonic level
transmitter makes it an excellent choice for
industrial application. The transmitter come
complete with an integral display featuring
three push buttons for programming and
diagnostics. The display is situated under the
lid for security and features just eight
parameters to set making is a very simple
devices to set up and use
