1. Product Brief Introduction:
The split type ultrasonic liquid level gauge disc mounted and wall
mounted split type machines have the advantages of a clean and
clear appearance, omitting the matching problem of standard
secondary meters, and providing great convenience for installation
and commissioning. They are especially suitable for new
construction projects and facilitate unified planning and design.
If equipped with a near type anti-corrosion transducer, they can
measure the liquid level of highly corrosive liquids.

5. 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.
