THEORY OF OPERATION The Mobrey MSP422 ultrasonic level transmitter is designed to be mounted above a liquid and uses ultrasonic pulses to continuously measure the distance to the liquid surface. The microprocessor-controlled electronics measures the time delay between the transmitting and the receiving of the reflected signals to calculate the distance (Figure 2-1).

When programmed with the bottom reference of the application – usually the bottom of a tank – the MSP422 computes the liquid depth (level) and outputs a 4–20 mA signal proportional to that level.

An LCD screen inside the enclosure displays the selected measurement. Programming of the MSP422 is achieved using the integral push-buttons inside the enclosure and the menu system shown on the LCD screen.

The MSP422 may be mounted in a non-hazardous areas only.
