1. Product Brief Introduction:
The integrated ultrasonic level gauge is widely used for liquid
level and volume measurement in tanks, water tanks, reservoirs, and
also for flow measurement in open channels. In practical
applications, many interfaces cannot be touched, such as situations
where the measurement equipment is corroded (by acids or alkalis),
contaminated by the measurement equipment (in sewers), or where
substances that cause adhesion (adhesives) are present on the
measurement device. Since the measurement technology of the
integrated ultrasonic level meter is based on the non-contact
ultrasonic principle, the integrated ultrasonic level meter is
suitable for liquid and material level positions that cannot be
accessed by physical means.

4. Measuring Principle:
The ultrasonic level gauge is vertically installed on the surface
of the liquid, emitting an ultrasonic pulse to the liquid surface.
After a period of time, the sensor of the ultrasonic level gauge
receives the signal reflected back from the liquid surface. The
signal is selected and processed by the transmitter circuit, and
the distance from the liquid surface to the sensor is calculated
based on the time difference between the ultrasonic level gauge
emitting and receiving ultrasonic waves. Due to the use of advanced
microprocessors and unique EchoDiscovery echo processing
technology, ultrasonic level gauges can be applied to various
complex working conditions. Integrated ultrasonic level gauge
refers to an ultrasonic level gauge with a probe and a housing
combined together.

6. Installation:
1) The distance from the sensor emission surface to the lowest
liquid level should be less than the range of the selected
instrument.
2) The distance from the sensor emission surface to the highest
liquid level should be greater than the blind spot of the selected
instrument.
3) The emission surface of the sensor should be parallel to the
liquid surface.
4) The installation position of the sensor should try to avoid
positions where the liquid level fluctuates violently, such as the
inlet and outlet directly below.
5) If the pool wall or tank wall is not smooth, the instrument
needs to be at least 0.3m away from the pool wall or tank wall.
6) If the distance from the sensor emission surface to the maximum
liquid level is less than the blind spot of the selected
instrument, an extension tube should be installed with a diameter
greater than 120mm and a length of 0.35m to 0.50m. The extension
tube should be installed vertically with a smooth inner wall, and
the opening on the tank should be larger than the inner diameter of
the extension tube. Alternatively, the pipe can be directly
connected to the bottom of the tank, with a diameter greater than
80mm, and a hole can be left at the bottom of the pipe to
facilitate the flow of liquid.
