3-1 Monitoring the Liquid Level (K3MA-J)
Application
• K3MA-J monitors the liquid level.
• Using an ultrasonic displacement sensor, E4PA-LS600-M1, the distance to the
liquid level is detected.
(When the distance is 800-6000 mm, the output of the E4PA-LS600-M1 is 4-20
mA.)
• The unit of indicated values by the K3MA-J is "m", and the values are indicated
to three decimal places.
• Four measurements are averaged for stable indication.
• Since the liquid can not be completely discharged, the liquid level less than 0.05
m is always indicated as 0 m.
• When the liquid level reaches 4.5 m, the comparative output 1 is turned ON.
• When the liquid level decreases to 0.5 m, the comparative output 2 is turned ON.
