Metex 3200U Ultrasonic Flow & Level Monitor - Manual (Page 32)

POWER INPUT OPTION
12VDC OR 24VDC
Ultrason Level & Flow Monitors may be ordered factory-configured for 12VDC, or 24VDC power
input.
QUICK BENCH TEST:
Connect Sensor as shown below, then Power. When properly connected a soft clicking can be heard
from the sensor and figures will show on the large LCD display. Test operation of the Ultrason by
holding the sensor steadily and aiming at a flat, stable target 12 to 28" (305 to 711 mm) away from the
end of the sensor. Allow a few seconds for the Ultrason to lock onto the target before displaying its
distance. The Ultrason will now display Range in ft or cm (factory calibration).
