High range point: The distance from the reference plane to the position. The value is positive when the
high point of the range is higher than the reference plane, and negative when it is lower than the
reference plane. When the liquid level is in this position, 20mA current is output.
① Alarm mode: select high alarm, low alarm or off.
Low range: The distance from the reference plane to the position. The value is positive when the low
point of the range is higher than the reference plane and negative when it is lower than the reference
plane. When the liquid level is in this position, 4mA current is output.
(4) With relay: Enter the alarm setting option and set three parameters:
② Alarm value: high alarm: alarm when the liquid level is higher than the alarm value
Low alarm: alarm when the liquid level is lower than the alarm value
③ Hysteresis value: Hysteresis value is to prevent measurement error from causing the alarm
switch to jump repeatedly near the alarm point.
High alarm state: the alarm will be canceled when the liquid level is lower than (alarm value-return
difference value)
Low alarm state: the alarm will be canceled when the liquid level is higher than (alarm value + return
difference)
(5) Please set the probe selection, parameter calibration and algorithm selection under the guidance of
professional technicians.
(6) After the equipment is installed, it must be truly grounded separately, and not with the common
ground of the electrical box or meter box.
(7) Suggestion: When the ultrasonic level meter is connected with interference equipment such as
inverters and PLCs, an isolation transformer should be added to the power part, and a signal isolator
should be added to the signal part, and reliable grounding should be done.
·The signal line should not be in the same trough with the power line and power line. It should be
installed separately through metal pipes, or installed away from the power line and power lines. At
least 1 meter.
·This is an important reminder, please read it carefully and do it strictly according to the
requirements.
·This is a general tip, please read it carefully to avoid causing trouble during use.

Others: Please do not modify the three items of probe selection, parameter calibration and algorithm
selection.
Due to the different on-site installation environment of the instrument. Therefore, the ultrasonic level
meter must know the basic conditions of the measurement before the work, such as: measurement
range, zero point, full range and field conditions, etc. Therefore, the instrument must be set before
measurement. For details, please refer to the “Easy Setting Operation Instructions of the Ultrasonic
Level Gauge Menu” on the first page.
Ultrasonic level meter (measure material level, liquid level) is a non-contact, high reliability, high cost
performance, easy to install and maintain level measurement instrument. It can meet most of the level
measurement requirements without touching the medium. It is a new generation ultrasonic level meter
with completely independent property rights developed by our company after many years of hard
work.
