2、After power-on display of the meter, long press the set button (SET) for 2s to enter in the main menu.

3、Input #1 probe height value to “reference zero point 1” which is arranged in the structural chart of the menu as shown in attached table (probe height is the distance from probe emitting surface to tank bottom or pool bottom).

4、Input #2 probe height value to “reference zero point 2” which is arranged in the structural chart of the menu as shown in attached table 1.

5、Set “4mA corresponding difference value” and “20mA corresponding difference value”

4mA corresponding difference value: output 4mA when the difference value is equal to the set value.

20mA corresponding difference value: output 20mA when the difference value is equal to the set value.

The “4mA corresponding difference value” and “20mA corresponding difference value” are situated in the structural chart of the menu as shown in attached table.

I. Purpose

Ultrasonic level difference meter (material level, liquid level) is used to measure the liquid level or material level difference between two containers.

         It is most commonly used to measure the water level difference in front and rear of coarse and fine racks at the water inlet of sewage treatment plant, calculate the water level difference and start up the back dragging cleaner to take out rubbish.

Minimum of measuring range: it is the value of distance between the reference plane to the position, which is positive when the minimum of measuring range is above the reference plane and negative when the minimum of measuring range is below the reference plane. The output current is 4mA when the liquid level is at such position.

Maximum of measuring range: it is the value of distance between the reference plane to the position, which is positive when the maximum of measuring range is above the reference plane and negative when the maximum of measuring range is below the reference plane. The output current is 20mA when the liquid level is at such position.

(6)The installed equipment must be grounded truthfully and independently and shall not share the public grounding with electrical cabinet or meter box.

(7)The signal line shall not be wired in the same trunking with the power line and it shall be installed independently through metal tube or far away from the power line. If the signal line is not installed through tube independently, it shall be kept at least 1m away from the power line.
