SKE portable level transmitter is designed to offer a simple, accurate, rapid, and reliable method of Liquid level measurement.
It features a truly non-invasive sensing technique.
When the magnetic probe is bonded to the bottom shell of the tank, an ultrasonic sound wave travels through the tank and reflects back from the media surface. The system calculates the height of the liquid, from the time taken for the signal to be received.
Signals from the transducers are fed into the processor, then indicate the level on the LCD.
Portable for walk-around check
No coupling agent required
No moving parts
External Measurement, 100% Safe
The sonar wave signal is emitted from the probe sensor, and the echo signal is detected after being reflected form the liquid surface. The echo signal is processed by the SKE algorithm then calculate the time “t”, and the system calculates the liquid level according to the formula below:
H: The height of the liquid level
t: The time taken by the sonar wave from launch to return
tg: The transmission time of the sonar wave in the tank wall
v: The speed of sonar wave propagating in liquid
α: Correction factor
Two Wire Non-Intrusive Ultrasonic Level Gauge
The Non-Intrusive Ultrasonic Level Gauge is in use everywhere where the level of liquids in tanks has to be measured continuously and contactlessly. Application possibilities for radar gauges can be found in almost all areas of industry. Sewage treatment plants and water purification plants in particular, but also other environmental engineering facilities as well as power generating stations now rely on cost-effective radar sensors for continuous level measurement.
In general, the dynamic viscosity of the measured medium is required to be less than 10 MPa. S. When 10 MPa. S < dynamic viscosity < 30 MPa. S, the measure range may be reduced and the blind area may be increased. It cannot be measured when the dynamic viscosity is > 30 MPa. S. (1 MPa. S = 1 CP). There should be no dense bubbles in the liquid; there should not be a large number of suspended substances in the liquid, such as crystals; there should not be a large number of sedimentary substances in the liquid, such as mud and sand. The temperature of the measured medium shall be within – 50 ℃ ~ 100 ℃.

The probe sensor must be clamped directly under the container.
This ultrasound liquid level meter can be used on the storage tanks, cylinders, and any Single Layer holding vessel made of Hard Materials.
– For magnetic container, it is bonded by magnet, hand-free use.
– For non-magnetic vessel, use hands to clamp it tightly on the wall.
