Split-type Ultrasonic Liquid Level Gauge

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.

4. Selection:

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.
