Page 2: Panel Description
PANEL DESCRIPTION There are three buttons on the panel, via which the meter can be adjusted. The measured values are displayed on the LCD screen after the adjustment. Button Buttons • Enter menu item • Move cursor Confirm menu item Choose menu item •... - Page 3 ② Under material level measuring mode, the positions of reference zero-point, maximum of measuring range and minimum of measuring range are as shown in Fig. 1.2. Fig. 1.1 Diagram of Distance Measurement Fig. 1.2 Diagram of Material Measurement Level 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.

- Page 5 Selecting measuring range Measuring range is decided by the range of ultrasonic probe which is subject to the site working environment, object to be measured and temperature, etc. Decide the measuring range needed based on the table below: Attenuation Attenuation Liquid Surface Magnification of Measuring Range Multiple...
- Page 6 The calculation method of signal attenuation is to add all signal attenuation amounts if there are several conditions on site. With little feedstock 5...10dB With little steam 5...20dB Temperature difference between probe and medium surface ≤40ºC 5...10dB Total minimum: 15dB, maximum: 40dB Under such circumstances, if the actual maximum measuring range is 5m, ultrasonic level meter with measuring range of 50m should be selected for the measurement.
- Page 7 LIQUID MEASUREMENT Flat-Top Tank Normally, the flat-top tank comes with a short connecting pipe with a datum plane that forms the undersurface of the flange. If the connecting pipe length is ≤60mm, inner diameter is ≥100mm and inner wall is smooth and free of burr and bulges, the measurement can be carried out if the emitting surface of installed probe is 3cm below the flange undersurface.
- Page 8 Probe installation on nipple joint Similarly, the other type of sensor can be installed via top hoisting thread and the dimensions of hoisting thread include M30×1.5, M32×1.5 and M38 ×1.5. Hoisting thread connection at the separate type probe top Arch Tank Top For arch tank, it’s better not to install the meter in the middle of the tank top.
- Page 9 Installation on flange – arch tank top For most arch tanks, the length of connecting pipe plus flange on the top is 150-180mm. But the part below the probe thread of ultrasonic level meter is not long enough (elongated probe is available for customization to make sure the probe emitting surface is below the connecting pipe bottom).

Page 10: Flange Installation
As the open container has no focusing effect, the sensor can be installed in the middle of the container. Installation on open container – with support at the top middle part Draining Well and Common Well Normally, the wellhole and wellhead of drainage well are narrow, and the well wall is uneven, which makes it difficult to conduct ultrasonic measurement. - Page 11 Integrated-type sensor installed on container flange Separate-type sensor installed on container flange Installation via Nipple Joint During installation via nipple joint, the probe must be exposed for at least 2cm above the connecting pipe bottom. Integrated-type sensor – installation via nipple joint...

Page 12: Doorframe Installation
Doorframe Installation Doorframe installation is ideal for the open container and the axis of connecting pipe must be aligned to the container opening or perpendicular to the medium surface. Integrated-type sensor – doorframe installation During installation for material piles in open air, several meters are required for measurement. The meters can be fixed on the hoist frame and sensor probe should be aligned to a medium surface. - Page 13 Connecting pipe cannot be soaked in the viscous medium If the medium is non-adhesive, the extended connecting pipe can be soaked in it for a long time (as long as the pipe is not corroded by the liquid and no impurities come in contact with its inner wall). In this way, measurement can be more accurate. The inner diameter of connecting pipe should be as great as possible and the inclined cut must be smooth.
- Page 14 Extending the connecting pipe for solid measurement Measurement of solid medium is different from that of liquid. The conical extended connecting pipe with an angle of 25°~30° should be used. Extended connecting pipe for solid medium measurement Devices and installation in the container ★...
- Page 15 The devices in the container such as pipe and support will affect the measurement. For accuracy of measuring points, it must be ensured that no other devices are within the diffusion range of ultrasonic wave signal. Barrier in the container - pipe The sensor should not be installed in or above the charging feedstock flow and it should be kept at a distance from the feed inlet.

Page 16: Common Installation Errors
Barriers at the pool bottom – reflect with a deflector If there is strong eddy or vortex in the container, such as eddy caused by the stirrer or strong chemical reactions, the measurement can be difficult. The ideal method is to install the sensor probe in the waveguide or by-pass pipe for measurement. Great fluctuation at medium surface –... - Page 17 ② Incorrect installation direction of the sensor If the sensor is not aligned to the medium surface, the measuring signal will be weakened. To ensure the best measurement effect, the axis of sensor should be aligned to the surface, i.e., perpendicular to the surface of measured interface. Sensor probe should be perpendicular to medium surface ③...
