AK2000E Ultrasonic Liquid Level Sensor
The Apure AK2000E measures liquid level without contacting the liquid. Mount the ultrasonic sensor above the surface with a clear path for the echo.
- Non-contact liquid level
- Ultrasonic echo measurement
- Level or distance display
Measuring level with ultrasound
The sensor emits a sound pulse through the air space and measures the time it takes for the echo to return from the liquid surface. The instrument converts that time to distance. Set the empty reference so that the indicated level is based on the required tank datum.
Mounting and first reading
Keep the maximum liquid level outside the specified dead zone and check that the lowest liquid level is within the usable distance range. Aim the sensor at the liquid surface and keep pipes, ladders and inlet streams out of its beam. Heavy foam, condensation or a disturbed surface can weaken the echo. Compare the displayed distance with a known distance after installation.
Confirm which listed distance range is supplied. Check the dead zone, pressure reference, temperature and output configuration against the tank and its highest and lowest expected levels. The earlier overview listed a 4–20 mA analog output and 2 relays. Verify these against the ordered wiring diagram.
