Description

 

 

1. Principle of Trumsense Ultrasonic Sludge Level Meter

The Ultrasonic Sludge Blanket is instrument of measured sludge, which is contact, high reliability, cost-effective, easy to install and maintain. It achieves the detection of underwater sludge level by spreading of the liquid and owns the independent property rights with development for many years by Trumsense.

 

 

 

 

2. Basic technical parameter:

As different installation environment, please learn the basic situation before the Ultrasonic sludge blanket works, such as   measure range, zero point, full range and field conditions and so on.

Note: The probe and algorithm selection, parameter Correction, please don’t modify them on yourself.

About temperature compensation

Temperature has an impact on the propagation speed of ultrasonic waves, resulting in errors in ultrasonic measurement. Meikong MP ultrasonic level gauge is equipped with a temperature sensor for temperature compensation to ensure measurement accuracy.

4. Installation of Trumsense Mud Level Meter:

Please follow them as bellow when you choose the installation location:

1) Keep the sensor perpendicular to the dirt surface and the bottom surface.

2The probe should be completely submerged in water and away from the wall at least 50 cm, if the wall is vertical up and down and the surface flat. If the wall is not flat, the distance is 100cm. If the wall is not up and down vertically, then you need to adjust according to the actual situation.

If the wall is rugged, or with some objects (brackets, pipes ), in order to avoid interference of measurement caused by the above objects, please increase the distance from it.

3There isn’t any obstacle in the emitting surface under of the probe, so the ultrasonic signal can’t block and reflect by obstacles

4The installation of probe should be away from the gas bubbles and floating solids which cased by Velocity mutation, so as to ensure precise and stable of measurement.

6. Trouble Shooting and Solutions  of Trumsense Mud Level Meter:

Symptom

Reason

Solutions

Failure work

Not connect power supply

Check the power line

 

 

The sludge blanket is running, this mark “▲” which showed on the screen isn’t change, it means the system is in the state of lost wave.

1. Measured distance beyond the range of product

1.consider the longer range

2. Measured medium have strong interference, vibration or more foam.

2. waiting for calm of the material, the device will return to normal measurement.

3.There are interference sources such as frequency converter, motor and so on in the environment.

 

3.Check the surrounding environment and shield the electromagnetic. Do not use the same power with frequency converter, motor and reliable grounding.

The input and output line can’t share one channel with inverter, motor, or galvanized pipe wear protection separately.

4. The probe doesn’t aimed at the measured surface .

4. Restall the probe, make sure to perpendicular to the surface mud.

5. Measured space has unnecessary object, such as  trash and so on.

5.Choose new installation position to  avoid to appear interferent.

6. The sludge blanket enter blind area.

6. Raise the probe installation position or make mud position lower

7. Measured liquid contains a lot of foam, turbulence or sediment.

7. Eliminate foam can consult manufacturer.

 

8.No echo

8.the probe is sloping, not aimed at the target

9.Measured distance within the range of product, but don’t receive the echo signal.

9. Select low frequency probe.
